What Is ITE Power Supply and Its Function?
ITE stands for Information Technology Equipment. Such devices are basic cords and plugs, which you can buy for a wide array of computer or electrical equipment.
Information Technology Equipment is also a group or family, or product. It involves devices with the main function associated with data collection, storage, transfer, or processing. These devices predominantly produce an assortment of periodic pulse electrical waveforms.
Devices with only auxiliary data processing functions are under other product family groups. Usually, ITE equipment is low voltage in nature, under 600 volt-rated supply.
A good example of ITE might be like:
- network HUBs
- drives
- servers
- printers
- keyboards
- monitors
- telecommunications equipment
- computers
Learning that numerous plugging accessories are out on the market can put your mind at ease. Plugs don’t seem to have a longer life span. That’s especially true if somebody trips over and breaks it. A dog chews in half, or a shortage burns it out. A demand for a stable and robust power supply plug will always be around.
ITE power unit accessories range from various plugging extensions for various devices. Its excellent selection makes an ITE power unit stand above the rest. Every device’s cord or plug is available in their gallery.
Their strong plastic coating can have a longer lifespan if properly managed. ITE power supply is the benchmark for dependable plugs for any equipment. Without a proper power supply flowing through the veins of your computers, a single power surge could wipe out all your hard-earned work.
Types Of ITE Power Supply
In choosing an ITE power supply, you may choose between a wall mount and a desktop power supply. Each has pros and cons, and selecting the ideal ITE power supply will depend on your preferences and needs.
Wall Mount Power Supply
Wall mount power supplies include wall adapters, wall bumps, AC adapters, wall plug transformers, power cubs, and liner wall mounts, among other things. Regardless of the name, such power supplies are the most typical low-voltage power source.
They are composed of small plastic boxes, which plug straight into the wall. However, they come in a broad spectrum of quality and performance levels.
The wall-mount power supply is an excellent space-saving option. That’s because you only need to plug one end into the wall and the other into your electronic device. That also saves you energy and time.
These power supplies could be either:
– Regulated or unregulated
– Switching or linear power supplies
Desktop Power Supply
When you need a power supply that offers much more power than a wall adapter, your ideal option would be a desktop power supply.
Desktop power supplies are similar to wall adapters in that they plug directly into the wall outlet and the device. These power supplies can offer more power than wall adapters and usually have various features and more agency approvals.
Remember that desktop power supplies normally have two components: the AC power cord and the actual supply with an attached DC cord. A desktop power supply may or may not come with an AC power cord.
It’s available in three standard types: a 3 Prong Mickey Mouse style cord, a 3-prong standard cord, and a 2-prong standard cord.
As with a wall-mount power supply, an essential thing to check is the type of DC connector the device will require. DC output connectors include 2.5 millimeters or 2.1 millimeters x 5.5 millimeters outer diameter female, 3.5 millimeters, 5-pin, 4-pin, and 6-pin DIN male, and tinned and stripped wires.
How to Choose the Right Type of ITE Power Supply
ITE power supplies are a vital part of all electronic equipment. They offer regulated voltages and protection to your electronics, executing essential functions to accomplish a device’s intended use.
For instance, AC-to-DC power supplies serve as an interface and offer isolation between the hazardous alternating current of the power utility and the needed low-voltage direct current.
Choosing the perfect ITE power supply is essential for a successful product. The continuous goal of increased efficiencies, reliability, and density requires a thorough check of power specifications.
Temperature, load, input voltage, product life, and cooling are essential considerations. So are meeting standards for regulatory environmental impact compliance, Electromagnetic Compatibility, and standards for safety.
Safety requirements
Today’s ITE power supplies should meet rigorous safety requirements and performance testing, adhering to different EMI and EMC standards. For example, medical equipment should meet medical equipment safety regulations.
In most cases, power supplies for ITE or commercial equipment don’t deliver the performance medical devices require in terms of product life, reliability, and safety.
On top of safety regulatory requirements, EMC and EMI are defined for medical equipment as a collateral standard to the safety standard for most nations (Europe and North America) by IEC60601-1-2.
The standard determines EM emissions and immunity requirements. Consider different levels of interference immunity as their acceptance criteria for the immunity requirements.
For instance, it may be reasonable for a product to lose power momentarily during an electrostatic discharge or AC mains surge as long as it recovers. In other scenarios, it can continue operating without the event’s effect.
Consequently, stipulating an immunity standard without determining a level and acceptance criteria is insufficient and useless.
Application
Determining a power supply requirement requires detail, thoroughness, and knowledge of what kind of ITE power supply is ideal for the application. For instance, is an external versus an internal power supply required?
An external is a stand-alone product with its enclosure, AC input connector, and output connector. Internal power supplies, meanwhile, are embedded in their equipment.
Each has pros and cons: performance, convenience, size, and cost are all important things to consider.
AC input
The type of AC input is something you must consider. A Class I AC input features three conductors (earth ground, neutral, and line). A Class II input features two conductors (line two or neutral and line) and doesn’t have an earth ground.
Remember that Class II products are more universally acceptable, as some end users might not have an AC source with an earth ground. Nonetheless, Class II products need extra levels of EMI filtering and insulation.
They may cost more due to the challenge of achieving the needed performance output without an earth-ground reference.
Reliability and product life
These two are related but different. Reliability is measured when it comes to operation, failure, and probability. MTBF (Mean Time Between Failures) is a reasonable figure of merit when comparing products.
On the other hand, product life refers to component wear-out mechanisms and isn’t affected by the MTBF estimation. Thus, go for product-life data and reliability data.
A computer ITE power supply can be reliable but lasts more than a few years of constant operation. At the same time, medical ITE power supplies last about 5-10 years or more.
Installation Tips for ITE Power Supply
So, you have picked out your power supply and are ready to install it. You will need a standard head screwdriver and a well-lit place to work. If your office or home is prone to static electricity, you might also like to use an anti-static bracelet.
Before you go any further, ensure you don’t open the power supply’s metal casing. There are high-power capacitors inside, which can kill or injure you if they discharge. For the same reason, do not stick wires or tools inside the exhaust or cooling fan holes.
Remove the old power supply.
Power down the PC and remove all the data and power cables. You’ll like to eliminate any access panels from the case. On a standard ATX case, those are on the left and right sides, held in place with screws on the computer’s back.
Remove the screws, pull back the access panels, and set them aside.
A form factor or other non-standard case will help if you consult the manual. Remove the exterior panels as you can to offer yourself maximum access to the interior. You will also need to unplug the power cables from different components.
Determine all the components plugged into the power supply. That will be the motherboard, case fans and radiators, graphics cards, drivers, storage drives, and CPU.
Check from both sides of the PC and multiple angles. Excess lengths of data cables and power cables are stored behind the metal motherboard mounting try.
If the power supply is modular, remove the power rails from the power supply housing’s back. If it is not, pull all the power rails to the most accessible space and ensure they are free of entanglements.
Installing the new power supply
Put the new power supply in position in the PC. Do not plug anything into it if it’s modular. If it’s not, trail the power cables outside of the PC for simple access.
Position the exhaust fan on the bottom or top of the ITE power supply away from the motherboard and internal components. Point the exhaust fan at the top of the case. If it’s bottom-mounted, point it down.
Secure the power supply to the PC’s rear case with the retention screws. Use the screws from the recent power supply if you are replacing it, or else the screws must have come with either the ITE power supply itself or the PC case.
After fixing the power supply, plug in all the cables. As you plug them in, know where you run the power cables. The PC inside does not have to look like a showroom, but ensure the data and power cables do not trail near the cooling fans.
Once you’re confident everything is good, move your PC back to its position with your monitor, keyboard, and mouse before closing up. Please don’t touch any of the interior components while it is running. Then, plug all and power it up.
If everything looks great, unplug the external cables, close up its access panels and screw them into place to get the PC ready for operation.
Tricks For the ITE Power Supply
Always consider the safety class
When mounting the power supply, it’s essential to observe the needed clearance and creepage distances to the equipment enclosure to all supply faces. The Class I system will guarantee 3-4mm between the earthed metal part and any part of the ITE power supply.
But that will depend on whether the end application is medical or industrial power supplies, necessitating the use of insulators around the power supply assembly.
Where you use a Class I power supply to the ground connection is a vital part of its safety system. Ensure it’s properly connected to the system safety ground.
If you use a Class II power supply, the clearance and creepage distances may be needed to be bigger in metal enclosures. Even though often, the equipment enclosure is non-conductive where they use such units.
Thermal management
Open-frame ITE power supplies may have a higher power rating when the connection is cooled, force air-cooled, or even both. With any air cooling, the mounting position surrounding the space and surrounding parts is unique to every application. Hence, it’s essential to check the operating temperature of your components after installation.
That guarantees that the safety components don’t exceed the maximum ratings and that the service and reliability aren’t impaired.
Electromagnetic compatibility
Open-frame AC-DC power supplies often need two or three mounting positions so you can connect them to the ground. You need one of these connections for safety grounds in a Class I system. You can find it on the input side of the assembly.
The output common-code capacitors are vital to the EMC performance of the power supply. Ensure you connect it for optimum EMC performance, where the equipment utilizes a metal enclosure that is rarely a problem.
In plastic enclosures, either Class II or Class I configurations, it’s important to make other provisions for connecting such points to guarantee EMC compliance.
