Schneider Electric Power Supplies
Schneider Electric makes power supplies and emphasizes their versatility. They offer a wide variety of power supplies to suit different needs. They range from simple units for basic applications to more complicated ones with advanced features and many outputs. Schneider Electric power supplies are built with sturdy components, designed to withstand the test of time and the rigors of life in an industrial setting, including the extremes of temperature, vibration, and electrical noise that can be encountered there.
Efficiency in energy use is one of the most fundamental features shared by all Schneider Electric power supply products. Right from the start, every aspect of their power supplies is designed to minimize energy loss. All their products are quiet, reliable, and efficient. And they always lead the industry in "eco design" principles, which optimize a product's environmental aspects right from the design stage.

How to Select and Size a Power Supply
A power supply alters power from one type to another and ensures that the voltage being delivered is the proper level, with the right characteristics, to enable equipment to function properly.
Power rating
If a power supply is rated for 5 amps at 24 VDC, (where voltage times amperage equals total wattage) the power rating for that power supply is roughly 120 Watts. This rating is very important because if this number is exceeded, it can cause a failure of the power supply and potentially damage other hardware wired downstream or on the load side of the device. To avoid this failure is important that the power supply is sized correctly.
Sizing a power supply
To properly size a power supply, identify what devices will be reliant on the power supply and what their total power consumption will be. The sum of all power to be delivered needs to be less than the total power rating of the power supply. For example, if the devices combined for a total of 100 Watts, then a 5 AMP power supply, which is rated for up to 120 Watts, would be sufficient. However, if the sum of those devices’ total power requirement is greater than that of the power supply rating, then a different power supply should be selected. It is important to allow for a buffer or safety factor. When sizing a power supply, never select a power supply that is rated for the same amount of power as the total power requirement of all of the devices. Oversizing the power supply will allow for changes and additions that may occur in the future.
