Why Does the Air Purifier Not Working?

Do you need clarification on what makes a good air purifier? Do you need help picking the best air cleaner? Perhaps your air purifier is malfunctioning, and you don’t know how to fix it. 

This guide will give you a detailed overview of what you need to do to fix your air purifier so it can start cleaning the air again! 

An air purifier’s job is to purify and clean the air. But if it is not working, the air you breathe becomes dirty. Before you rush out to purchase a new one, troubleshooting tips can save you some money. 

Remember that there are a few reasons an air purifier might stop working. Those are electrical or mechanical faults. The filter needs changing, runs at a too-low setting, is too close to a wall, or needs to be bigger for the room. 

How Do Air Purifiers Work?

To better understand what’s wrong with your air purifier, it will help if you learn how most air purifier work. When we talk about filter-based models, they feature a set of internal fans that draw air in. It runs through the filtering mechanism and spits it into your living space.

On the other hand, ionic purifiers release negatively charged ions into the atmosphere, which bond and weigh down airborne pollutants. Another thing you must keep in mind is the benefits of using an air purifier. 

What are the Common Problems of Air Purifiers 

An air purifier won’t work if it has a loose or damaged fan, an improperly installed filter, a clogged filter, or a frozen motor. Poor maintenance, an old filter, power cord failure, or unresponsive controls can also stop it from running.

You need to reset the device after repairs to guarantee it works properly. 

Problem #1 – Old filter 

Your air purifier might stop working because the old filter needs replacing. 

When we talk about filter replacement, every manufacturer has its guidelines. For instance, GermGuardian and Levoit air purifiers suggest changing the filter after six months.

Other air purifiers have a combination of filters. You should clean it regularly to optimize the home’s air quality. Specific manufacturers insist on utilizing a genuine or specific filter for filtering replacement.

Always read the manual if you’re uncertain when to change the filter. Fortunately, many air purifiers have a filter change indicator light and sound alert to remind you to change them. 

So, how can you determine if the air purifier needs filter replacement? 

  1. Pay attention to the filter change indicator reminder.
  2. You can consult your user manual to know when to change the filters.
  3. Test the air purifier’s airflow by checking if it’s blowing out any air and listening to determine if the fan is noisy. That can mean that the filter requires replacing.
  4. When changing the filter, mark it in your calendar and track the time to understand when you should do it again.

How can you change the filter of your air purifier? Follow the steps below.

  1. Turn off and unplug the air purifier.
  2. Based on your model, remove the cover of the device.
  3. Eliminate the old air filter by pulling off the air purifier. 
  4. Install the new filter by sticking it into the air purifier.
  5. Look at the arrow on the filter to guarantee proper installation. Most filters have arrows or something similar. The arrows must point toward the air purifier.
  6. Replace the cover and tighten it. 
  7. Rest your filter change indicator.

Problem #2 – You installed a generic filter

A generic or non-filter can easily become the cause of the malfunction of your air purifier. Most manufacturers state that you must only use their brand filter.

Make sure you use the proper filter brand. Utilize the proper type of filter. Installing a carbon filter with a combination filter isn’t a brilliant idea. Make sure you use the proper filter size. It won’t fit into the slot properly if you purchase a too-big filter. But if it’s too small, it won’t cover the entire space, and dirt and dust will pass through. 

To fix this, make sure you:

  1. Consult your user manual to ensure the proper filter type is compatible with the air purifier.
  2. Check to determine the type of filter you need. Does it need a carbon filter, HEPA, or a combination?
  3. Learn the filter’s size to get before purchasing one.
  4. Purchase an added filter for future replacement during your purchase. 

Problem #3 – Irregular maintenance

Without proper maintenance, your air purifier won’t function properly for a long time. Regular use of an air purifier without correct care may cause the motor or fan to malfunction.

Also, the air purifier will perform properly and last a long time if you maintain it. If the air purifier is malfunctioning, and you haven’t done your maintenance, it’s time for you to consider one. 

Here’s how you can maintain your air purifier:

  1. Check the air filter regularly and replace it when needed. But it will depend on your home’s overall air quality.
  2. Listen to the flashes, beeps, and tones of the air purifier. They all mean something.
  3. You should reset your air purifier regularly. Reset it after opening it, changing it, or cleaning the filter.
  4. When replacing the air filters, ensure you only utilize the suggested tips by the manufacturer.
  5. Remove dirt and dust from the carbon filter using a vacuum cleaner.
  6. For air purifiers with UV light, check that the UV light on the air purifier is on. That kills disease-causing bacteria, making the air you and your family inhale healthier.
  7. Avoid washing and reusing combination filters. Instead, replace them regularly. 

Also, on no account should you use your air purifier outdoors.

Problem #4 – Power cord failure 

One of the common reasons your air purifier may not be running is a power cord failure. No household appliance or device will work if there’s a problem with the power cord. The same applies to air purifiers.

If the power line breaks or there are burnt components, expect it to not work.

If the air purifier suddenly stops running and you clean and replace the filters, reset it after every filter change. Create a regular maintenance plan and check the power cables, as they can be the culprit.

To fix this, do the following:

  1. Check your power supply.
  2. Plug another appliance into the outlet to determine if it works.
  3. Try another outlet.
  4. Replace your power cord. 

If you need an efficient and practical power supply for your air purifier, Prowin Power got you covered. 

Problem #5 – Unresponsive controls 

Every air purifier has controls for adjusting the device models. Depending on your model, air purifiers have push buttons or touch controls. Over time, it’s possible that the controls will not respond or that the filter cover isn’t attached properly and stops the controls from running.

That can happen because of a stuck button or the user hits it too hard, causing it to be damaged or jammed. Also, the power supply or filter cover may malfunction if the controls aren’t working, leading the air purifier to stop working. 

Here are some solutions for you:

  1. Verify that you turn on the air purifier.
  2. Check if the power button is damaged or stuck. 
  3. Change the filter cover of your air purifier based on the instruction from your manufacturer.
  4. Contact customer service or consult your user manual if you’re having problems finishing the task. 

Problem #6 – Damaged or loose fan 

A damaged or loose fan can be another cause of an air purifier’s malfunction. Have you bumped or dropped your air purifier? Perhaps you used the fan for an extended time. Remember that a fan can become loose, causing the fan’s position to change.

Also, a damaged fan is a typical cause of an air purifier not working, as it won’t function even if it’s only slightly damaged. 

Some of the fixes you can do for your damaged fan:

  1. Turn off and unplug the air purifier.
  2. Remove the cover and remove the intake grilles with foam pre-filters and the filters.
  3. Remove any screws securing the filter housing.
  4. Remove the long screws that keep the main housing together and detach the pieces to access the fan.
  5. Assess the fan to determine if it’s broken or damaged.
  6. If yes, contact your device’s customer care team for a fan replacement. 

For your loose fan, consider doing the following fixes:

  1. Turn off and unplug the devices.
  2. Dissemble the air purifier by removing its cover.
  3. Check the fan for loose screws.
  4. Tighten the screws with a screwdriver.
  5. Reassemble and change the cover and tighten it.
  6. Reset the air purifier when done. 

Problem #7 – Reset needed 

A malfunctioning air purifier may also need some resetting. You should reset your device after a filter change or just after opening the unit. It won’t function until you reset it.

Here’s how to do it:

  1. Turn off your device by pressing the power button to reset it.
  2. Other air purifiers may have a blinking red light. Once the reset light blinks, your air purifier will begin making noise.
  3. If your unit has a HEPA filter, it will display HEPA reset.
  4. Press and hold the air purifier’s power button until you see the light stops blinking.
  5. It may have a tiny button that you can use as a paper clip to press and hold for three to five seconds.
  6. Your filters are not reset. Turn it off and back on. 

Problem #8 – Incorrectly installed filter 

Did you know that an air purifier may produce noises or not work if you do not install the filter correctly? If you hear sudden noises coming from the device, it’s a sign that something is wrong.

Other air purifiers have a red light feature, informing you if the filter is malfunctioning. For instance, if you install the filter backward, the air will have difficulty passing the material. Your air purifier will work overtime to compensate for the lack of airflow, leading to it not working.

Here are some quick fixes for you:

  1. Turn off and unplug the device from the power source.
  2. Disassemble it by removing the cover and the air filter by drawing it off the air purifier.
  3. If the filter has an arrow, you can confirm if it’s not installed correctly by checking the arrow on the filter. Reinstall it properly. The arrows must point toward the air purifier.
  4. If it doesn’t have an arrow, consult your manual to determine how to install the filter properly.
  5. Change the cover and tighten it up. 
  6. Reset it as usual.

Problem #9 – Clogged filter 

A clogged filter is the most typical reason for your air purifier not working. Dust, pet dander, dirt, and other contaminants could clog filters, limiting the device’s efficiency.

You will find different air purifiers, each with its model and set of filters. Nonetheless, some of the commonly used filters are media filters, washable filters, electrostatic filters, UV light filters, carbon filters, and HEPA filters.

Other air purifiers only use one type of filter, while some use a combination. Your air purifier can stop working if those filters are not correctly replaced or cleaned. 

Here’s how to deal with it.

  1. Turn off the unit and release it from the power source.
  2. Remove the cover and unlock it to access the filter.
  3. Detach the pre-filter and check if you need to clean or replace it.
  4. Find black spots or any discoloration on the pre-filter and clean it.
  5. Change the HEPA filter with a new one if it’s black or grey.
  6. Reinstall the pre-filter and tighten the cover.
  7. Reset it as usual when done.

Choose the Right Power Supply for Your Air Purifier

Keeping the air fresh and pure is a necessity nowadays. An efficient air purifier may help keep your home’s environment clean and fresh by removing toxic viruses.

Fortunately, different air purifiers are accessible in the market, but many brands provide vague explanations about their product’s efficiency or make freakish health claims. 

Air purifiers are not a magic bullet to improve your home’s quality, but the perfect air purifier may help you breathe better. Nowadays, it becomes more challenging for us to pick the ideal air purifier power supply.

But there’s no need to worry. Here we have provided a guide to help you choose the ideal air purifier power supply based on your budget and needs. 

What is an Air Purifier, and Why Do We Need It?

An air purifier sanitizes the air containing allergens, toxins, and contaminants. Essential oil diffusers and humidifiers that add particles to indoor air are the polar opposite of such devices. Air purifiers and filters work differently. Air purifiers can also sterilize particles, while the filters only eliminate them. 

Remember that an air purifier is a machine that removes pollutants from the indoor air and improves the air quality in your home, leaving the indoor space clean and contaminant-free. 

An air purifier eliminates contaminants from a room’s air to improve air quality. Dust mites, pet dander, ragweed, dust, pesticides, pollen, second-hand smoke, paint fumes, and mildew are only a few of the toxins that the air purifier filters.

Asthmatics, allergy patients, and anyone with an impaired respiratory system may encounter minor to major health concerns due to these particles. 

An air purifier can purify the air from a broad spectrum of allergens and pollutants, which can be difficult on a person’s health in the long term. The benefits of these devices extend beyond purifying the air from standard pollutants.

It removes smoke

Are you a smoker? Living in a wildfire-prone area? Perhaps you don’t have a well-ventilated kitchen in your home. An air purifier can help eradicate the smoke produced by cooking, forest fires, and tobacco.

Also, air purifiers with a dense activated carbon filter can eliminate the odor caused by any smoke, while a True HEPA filter will filter out any visible smoke particles. 

It captures mold spores.

Mold is a typical issue in most homes, and an air purifier can capture any airborne mold spores before they can reproduce. 

Air purifiers with an activated carbon filter, a True HEPA filter, and ultraviolet light are ideal for mold spore removal. That combination will lower the odor, capture mold spores, and destroy them at their core. 

It traps viruses and bacteria. 

Millions of small virus particles and bacteria can float around your home. Those pathogens and microbes can result in all types of illnesses.

An air purifier can help trap the bacteria as it flows through the system. Nonetheless, that’s not efficient for viruses. To get rid of those, you will like an air purifier with ultraviolet light, which ruins the DNA structure of such viruses, rendering them harmless to your health. 

How Does an Air Purifier Work with Power? 

Electricity runs an air purifier. As with any electric appliance, you must consider the power consumption of air purifiers.

You can run an air purifier 24 hours a day. That sounds quite a lot, especially if you look at it from your electric bill’s point of view.

Fortunately, air purifiers consume a manageable amount of energy. They have a maximum wattage of at least 40W and 200W (even the largest ones max out at 100W). That is for the highest speed settings. Also, you can run an air purifier on a lower 10-to-30-watt stage. 

Many air purifiers consume at least 8 watts to 56 watts. A fridge uses at least three to five times more energy. They ran air purifier magnets with about as much energy as an iPhone charger. 

The voltage is the first thing you must consider when picking or creating a power supply for your air purifier. What voltage does your air purifier needs? That one is quite simple.

If your air purifier needs 9 volts, you need a 9V power supply. If it needs 5 volts, then you need a 5V power supply. On top of that, if your air purifier requires a DC voltage (the most typical), you require a DC output from your power supply. If your air purifier requires AC voltage, you need an AC output. 

In other words, small Purifiers may use the AC power from the wall socket. Meanwhile, large air purifiers need AC adapters or special wiring.

How to Pick the Suitable Power Supply for Your Air Purifier?

An old maxim says, “use the right tool for the job.” However, frequently, there are numerous tools for the job. Thus, how do you know which one to utilize? 

You must understand a few basics to pick the ideal power supply for your air purifier. 

Power Supply Terms

Clarify some confusing terms, but they are essential in choosing the right wall adapter power supply. Linear power supplies versus AC-to-DC switching power supplies are sometimes misleading terms to those people who are not familiar with them.

A switching power supply takes an AC input but filters and rectifies it into DC first. It’s converted back into AC at a high switching frequency and steps down the voltage with a transformer. It’s fixed and filtered into a DC output. 

On the other hand, linear power supplies take an AC input, step down the voltage with a transfer, then rectify and filter the input into a DC output.

The main modification between these two is that they enable various components you can use. On the other hand, the linear power supply is less efficient and utilizes a heavier and bigger transformer and bigger filter components.

The switching power supply indicates higher efficiency because of the high switching frequency, allowing it to utilize a smaller, less expensive high-frequency transformer and lighter, less expensive filter components. Switching power supplies have more overall components and thus usually are pretty costly. 

Power Supply Current

The air purifier you like to power will require a particular amount of current. If you purchase one, it must indicate how much current it requires somewhere in the technical documentation or by the power connector. 

For instance, your device requires 1 ampere. That indicates you should pick a power supply that can provide at least a minimum of 1 ampere. 

Watt 

Often, a power supply offers you several watts. Watt is only the voltage multiplied by the current. Therefore, if you have a 5-volt power supply that can provide a 1A of current, you will need a 5W power supply.

If the power supplies say 12V and 100W, you can figure out the maximum current by a basic calculation. 

Current equals the watt divided by the voltage. Thus, that’s 100/12 = 8.3A. 

Power Supply Voltage 

Another thing you need to keep in mind when buying a power supply is the voltage. That one is quite basic.

If your air purifier requires 9V, you need a 9V power supply. If it needs 5V, then you need a 5V power supply. 

On top of that, if your device requires a DC voltage, you need a DC output from another power supply. If your air purifier requires an AC voltage, you will need an AC output. 

Tips and Tricks for Choosing an Air Purifier Power Supply

You will find different uses of power in your daily life. Therefore, the demand for power product accessories like chargers, adapters, and LED drivers from Prowin Power is increasing.

Nonetheless, even though those products are accessible in the market at a high quality, people seldom talk about choosing the ideal power supply unit to power their air purifier. Those result in misuse, thus increasing the need for replacement.

Here are some tips and tricks for picking the best power supply unit for your air purifier. 

Ideal wattage for your system when selecting a power supply unit 

The initial step is to consider different ways to pick power supply wattage for your system. Each air purifier has particular power needs. When choosing, remember the minimum wattage rating for it.

You can utilize a decent power supply calculator to offer you an estimated figure when in doubt. The only drawback of picking too low wattage indicates your device will need more juice to power up, while extremely high watts might suggest you cannot use them. 

Consider wall outlets

You draw substantial power from the electrical grid when you plug an air purifier into the wall outlet. Remember that you can use a wall outlet to handle the big load of most appliances.

They also lessen tripping hazards, which are risky if something is wrong with either the plug or the outlet. Electrical appliances, generally, are better off plugged into a wall outlet. Furthermore, electrical appliances require a consistent flow of electricity that can warm cables as the day wears on. 

That is why it isn’t easy to plug in appliances in wet regions. That application could cause a power strip to overheat or trip the circuit breaker. Make sure you utilize a dedicated outlet when utilizing such machines. 

Verify the wattage.

Before connecting an extension cord to your air purifier, it’s wise to confirm its wattage to ensure you’re not straining the cable. You can do this by looking at the label of the extension cord.

Unless batteries power your air purifier, plug it into an electrical outlet. Plug-in air purifier versions have a fixed power connection attached to an electrical outlet while the devices operate. 

Choose the ideal extension cords.

When choosing an extension cord for your air purifier, there are some considerations you must pay attention to. 

Lower resistance and boost overall efficiency by using the shortest cord possible. The energy required to run the appliance increases when using an air purifier with an extension cord. That’s proportion to the extension cord’s length. Also, longer wires are more likely to become tangled, raising the risk of tripping over them. 

Choose an extension cable that is compatible with plugs having three prongs. Hence, the electricity is grounded, and no one will get an electrical shock. 

Avoid overloading the extension cables to lower the overheating and catching fire risk. 

Consider the length of the air purifier from the wall. 

For your air purifier to work properly, they need a massive space to draw in air and expel it into the room. When pressed against the wall, it can’t take in as much air as it would. It’s not simple to offer a conclusive solution to where you should place it. 

Place your air purifier in a good area for it to function properly. It will help if you consider other things, like positioning it near the source of pollution or ensuring it doesn’t cause problems with other equipment. 

If you have a portable air cleaner that you move from room to room, take it wherever you go. 

Final Thoughts on Air Purifier Power Adapter

To sum up, remember that you don’t need to put in a massive effort to create the power supply requirements you need for your air purifier if you use help from manufacturers and accessible resources.

Before any selection assessment, it is critical to determine your requirements. There’s a major difference between choosing what you need and what you’d want.

The power line of products from Prowin Power includes a broad spectrum of power supplies. We offer all your power source needs, from open/enclosed AC-to-DC power supplies, wall adapters, and table-top power supplies.

No matter which tool you pick as your power source, you can rest assured that you’ll receive top-notch products that are perfect for the job.

Power Adapters for Air Purifiers

12V0.5A 6W Power adapter or power board for Air Purifiers

36W Power adapter DC 12V/24V Output

LED Power Supply

Everything requires energy and power, whether in the form of magnetism, chemistry, or electricity. It’s not any different for LED setups. LEDs can’t be powered by the standard alternating current (AC) found in traditional wall outlets; instead, they require direct current (DC). Therefore, an LED power supply must convert the AC power to the DC power that the LED system needs.

Different kinds of LED power supplies

LEDs have two different power types: 1. A power source with a constant voltage, also called a lighting transformer. 2. A constant LED driver with constant current output.

1. Constant voltage power supply/LED lighting transformer

Constant voltage LED power supplies are sometimes known as lighting transformers. This implies that the output voltage is stable. It works great with the LED system, which has current-limiting resistors. Such as LED tapes, LED billboards, LED displays, and so on. DC 5V, DC 12V, and DC24V are three standard output voltages for LED power adapters.

2. LED driver with constant current

A constant current LED driver maintains a fixed output current regardless of changes in input voltage. That means the LED driver will supply a constant current to the LED lights, guaranteeing their consistent operation. It can power the LED systems without a current limiting device (like a resistor).

LED power supply vs. LED driver

The voltage or current regulation is the main difference between the LED power adapter and the constant current LED driver. The LED power adaptor regulates the voltage, while the LED driver regulates the current.

The type of LED makes a difference in terms of practicality. We need a constant current supply if we need to limit the current flowing through a LED. A constant voltage power supply is also workable if there’s a current limiting resistor.

Some LED lights and tapes have built-in current limiters, which can be powered by any constant power adapters with enough current.

How to choose the right LED power supply?

Now that we’ve covered the types of LED power supplies. Let’s talk about how to pick the best one. Below are some tips:

Wattage

Get the wattage of the led light first. If we want to power multiple LED lights with one power supply, we need to add up the wattage of all the LED lights.

Furthermore, remember the following: Use 80% of the power supply wattage. So, please apply the following formula: LED system wattage / 0.8 = LED power supply wattage. For example, the total LED system power is 100W, and the wattage of the LED power supply is 100W / 0.8= 125W. So we need a power supply with 125W or higher wattage.

Voltage/Current

Inspecting the LED system’s input voltage is critical since this will determine the power supply’s output voltage. Contact us if you need more information, or feel free to contact the company that made the LED system to find out more.

PFC(Power Factor Correction) or not

Utility power/mains supply benefits from power factor correction (PFC). As a result, the power supply costs will rise. A PFC is required in the LED business if the power supply exceeds 25W in wattage.

Certificates

Safety Certificate

Certificates of compliance with local safety regulations may also be necessary. Use a power supply that complies with local safety regulations. Not all LED power supplies are on the UL list for the US market. Prowin’s power adapters have passed the tests that UL requires for the LED industry.

Dimmable or not

Determine if the LED system needs dimming capabilities or to be adjusted for brightness. If that’s the case, double-check that your LED’s power source supports dimming. Specify whether a power source is dimmable and what kind of dimming control it uses. There are typically 5 different types of dimming controls: TRIAC dimming, 0-10 volt dimming, resistive dimming, 1-10 volt dimming, and pulse-width modulation dimming.

Application environment

Confirm the optimal location for the LED lighting system’s installation. It will be safe to install the power supply with the proper casing. The IP level indicates whether the power supply unit is dust-proof and waterproof. The power supply rated IP20 is often for indoor use, while those rated IP65 or IP67 are typically for outdoor LED systems.

Conclusion

The power supply for an LED system is a vital part of the whole. It verifies the proper operation of the LED lighting system. It’s not always clear if we require a constant voltage power adaptor or a constant current LED driver. Differences between the two will aid in our search for a solution. We need the correct power supply for our LED systems, and the above-mentioned six elements are crucial. When working with electronics, they must be risk-free and reliable.

3D Printer Power Supply

3D printers are all the rage nowadays, providing various avenues to bring their dream creations into real life. However, there is more to using a printer than the average person might expect. One common factor to consider is the 3D printer power supply options that will be usable. Fortunately, this guide offers helpful information we have compiled to get started.

What are 3D Printer Power Supply Units?

The two most common types of power supply units(PSUs) are linear power supply and switch mode power supply. The 3D printer power supply is the switch mode one, which is also called LED PSU. It works by delivering a fixed DC(Direct Current) voltage(like DC 5V, DC 12V, DC 24V). DC 12V and DC 24V are common types used in 3D printers.

How to choose the right power supply?

Now we get to know what is the 3D printer power supply. Let us move on to the factors to consider when buying the ideal power supply.

1. Budget. First on our list of options is to consider the specific amount of money we want to spend on a 3D power supply unit.

Many people prefer the ATX PSUs because they work well with P.C.s with higher quality than the LED power supply units. They’re costly but provide a wealth of safety benefits. And we need to modify them to work with 3D printers correctly.

Most metal case power supplies are also with safety guides. They’re more competitive and easy to wire, we can wire them with screws. It’s also a good option for 3D printers.

2. Voltage. 3D printers work through two main voltage outputs: the 12V and 24V types. The type of voltage that applies to any 3D printer device relates to the hot end on the unit, which exists on the labeling. Let’s discuss the variations between these two power supply units below.

Specifically, the 12v system features simple parts to acquire. A good example is the pumps, the pumps for the 24v pumps aren’t easy to find. Plus, the wires tend to be larger, and the cost of the 24v units is higher than those of the 12v types.

For the 24v system, the wire is smaller, its average cost is significantly less than the 12v system. When developing a 3D printer, various connections and cables must be present to ensure the best results. We’d better match our 3D printer with the correct voltage unit.

3. Wattage. It’s also crucial for us to evaluate each printer’s wattage and the heating bed’s power rating. Usually, this unit features a control board, a single hot end, five motors, and other components. On average, all of these units expect about 100 watts of power. When we combine this amount with the average rating of the heat bed, we will know the total amount of power wattage required.

One more tip is that the power we have calculated is only 80% of the power supply wattage. We should calculate correctly to get the right power supply wattage. For example: After calculation, the total wattage that the 3D printer needs is 200W, then we need the power supply wattage is: 200W/0.8=250W. So what we need to search for is a 250W power supply.

4. Input Voltage. It refers to what voltage the PSUs(power supply units) could accept from the wall socket. It usually exists on the label of the PSUs. Some power supply’s input voltage is from AC 100 to AC 240V, others can be adjusted from 110V to 220V(reversible) with a switch on the side of the power supply.

110V-220V-switch

What Are Some Reasons for Testing the Power Supply Unit?

Before we connect the plug-in adapter to the 3D printer system, performing a test is crucial first. Some reasons for such caution include:

  1. The consumer market features countless brands and models of PSUs. Each function is different, we must pick and confirm if it is the right power supply for our 3D printer.
  2. Since there are several connections when using the printer, we should confirm the connectivity before using each unit. It is a process that helps avoid instances of short-circuiting or possible fires.
  3. Confirm the power supply is workable and guaranteed safe, and avoid spending more money on a new 3D printer.

How to test the power supply?

We know how important it is to test the power supply now. Following is the steps to test the power supply.

1. Get a millimeter and check the power from the power supply unit. Once we know the wattage and voltage from the power supply, make sure they match the amount what the 3D printer needs. We recommend using the following video(from 10″ to 40″) as a point of reference.

2. Proceed to check if the DC port(DC Power Adapters) is compatible with the port on the printer. If not, we may have to invest in another cable for this process.

3. Evaluate the input voltage of the power supply. We may need to switch the right input voltage to ensure no burning issues can occur. Different regions have different ratings, such as AC110-120 volts in the USA, while the AC 220-240volts in European countries.

4. Double-check the above information, then connect the printer to the power supply unit.

5. If we plan on using an ATX power supply, we could find detailed modification suggestions in this tutorial on the RepRap wiki.

Conclusion

Choosing the right power supply unit is a crucial factor to consider when using a 3D printer. However, these units are sometimes costly, with the guide above, we will find it easy to test and pick the right power supply to get started. Test before using the power supply is super important. It will help us to save more costs and ensure our 3D printers operate well.

Power Supply Application

A power supply for electronic devices, converts one type of power(AC/DC) to the other type of power(AC/DC). It is also called “ac/dc adapter”, “charger”, “power adapter”, “converter”, “transformer” and “inverter”.

1. Types of power supply

Today we are going to discuss the application of the power supply. There’re 3 types of power supply:

1. AC DC adapter,  convert the AC input voltage to a DC output voltage.

2. DC to DC converter, convert the DC input power to a DC output power.

3. DC to AC inverter, convert the DC input power to an AC output power.

2. Application of Power Supply

Power supplies are used widely in many industries, like IT, home appliances, industrial, lighting, solar products, energy, etc. I’d like to categorize them by the above types.

2.1 AC DC adapter Application

The function of the AC DC adapters is to convert the AC input power to the DC output power, as many electronic devices need the DC power input.

Types of AC DC adapters

There’re several types of AC DC adapters, such as wall-mounted power adapters, desktop power adapters, switch-mode power supply, PD charger, etc.

Application

Applied for IT industry like signal boosters, routers, optical network terminals, etc.

Working with digital products like PC, printers or 3D printers, POS machines, cameras, cell phones, etc.

Applied for home appliances like purifiers, TV, smart speaker, telephones, etc.

Working in the LED industry like LED lamps, LED lights, LED screens, LED posts, advertisement boards, LED scoreboards, etc.

Applied in outdoor electronic devices, Medical Equipments, Instruments, etc.

Working with incubators, CCTV alarms, CCTV cameras, etc.

2.2 DC to DC Converter Application

A DC to DC converter is to convert the DC current from one voltage level to another(Discover), which is usually connected with smart lighting, cellular phones, laptop computers and vehicles.

Types of DC to DC converter

There’re many types DC to DC converters:

1. Magnetic Converters

2. Non-Isolated Converters

3. Step-down/Buck Converters

4. Step-up/Boost Converters

5. Buck-Boost Converters

6. Isolated Converters

They’re also applied in the Industrial control system, Semi-conductor fabrication equipment, Telecom or datacom system,  Medical devices and equipments, etc.

2.3 DC to AC Inverter Application

A DC to AC Inverter is a power electronic device that converts the input DC power to the output AC power. It’s one of the most important elements in power electronics. That’s because these inverters are necessary for many real-life applications.

Types of DC-AC Inverter

There’re 3 major types of inverters:

1. Sine Wave(“Tru Sine Wave” or “Pure Sine Wave”)

A sine wave(“Tru Sine Wave” or “Pure Sine Wave”) inverter gives waveform that you get from Hydroelectric power or from a generator.

2. Modified Sine Wave

A modified sine wave inverter actually has a waveform more like a square wave, but with an extra step or so.

3. Square Wave

A square wave is very simple, it switched the DC supply between positive and negative(Discover).

Application

The inverters could work with many devices.

1. DC power source usage. The inverter converts the DC electricity from batteries or fuel cells to AC electricity, which could be at any required voltage.

2. Uninterruptible power supplies. The inverter supplies the AC power (inverted from the battery) when the main power is off. To guarantee the devices work well all the way.

3. Electric motor speed control. Inverter circuits designed to produce a variable output voltage range, are usually used for motor speed controllers.

4. Solar system. The solar inverters are very important for the whole solar system.

5. DC transmission lines. The DC to AC inverters could also be used to transmit power to load.

Above all, different devices need different power supplies. Before choosing the right power supply, we should know more about the electronic devices and project details.
