Power Supplies

What are Power Supplies?

A power supply is a device that supplies electrical energy to an electrical load. It converts one form of electrical energy to another, such as converting AC (alternating current) to DC (direct current). Power supplies are used in a variety of electronic devices, from computers and cell phones to TVs and gaming consoles.

What Do We Supply?

We supply an extensive range of power supplies, including:
External Power Supplies
Battery Chargers
DC/DC Converters
LED Drivers
Internal Power Supplies (DIN rail, Enclosed, PCB Mount, Open Frame, U Frame)

Why Choose E. Preston?

In over forty years of being in business, we have built a reputation as a company that does business in a more traditional, perhaps old-fashioned way. In our customer service we pay attention to what some may see as small things, like ringing back when we say we are going to do so, and following through on promises.

We have staff who have expert knowledge and are happy to provide technical assistance to you on the products we sell, whenever you need it.

Where we can, we will ensure you get next day delivery on your product order, and we are also happy to discuss flexible payment terms if that will help.

One or great strengths at E Preston is our access to thousands of products, including power supply products, which will be suitable for a variety of uses and applications.

We have in stock, or can make available power supplies from well-known brand names such as Meanwell and Ideal Power.
If it is choice you need, then look no further than us
to discuss your power supply product requirements, or to ask a technical question.
