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.

FPR – High-Performance 5x20 Fuse Holder for Vertical PCB Mounting

  • 3.2 Watt rated power acceptance
  • For vertical PCB mounting
  • Suitable for 5x20 fuses
  • IP40 Protection class

Modern electronic designs require ever higher power density with reduced space requirements – without compromising on safety and reliability. The FPR fuse holder was developed precisely to meet these requirements. It offers an impressive 30% higher power consumption with the same footprint as the well-established FPG4 series. This means more thermal load capacity without taking up additional space on the PCB.

With a power consumption of 3.2 watts at 10 amps at 23 °C ambient temperature, the FPR significantly outperforms the previous generation. The housing dimensions remain compact at 12.5 mm, which enables simple 1:1 integration into existing designs. At the same time, the component meets all relevant standards with regard to vibration resistance in accordance with IEC 60068-2-6 and operates reliably in a temperature range of -40 °C to +85 °C. The IP40 degree of protection rounds off the technical profile.

Compatible with FPG4 Series
The FPR provides developers with a powerful, space-saving and easy-to-install solution that impresses with its high thermal load capacity – all without changing the existing layout. The new fuse holder is 100% compatible with the existing FPG4.

Application Areas
The FPR is particularly suitable for applications with high current loads and limited space – for example in industrial automation, mechanical engineering or building automation.
