In the second half of the last Century, the combination of huge global technological advances and the Cold War contributed to a very different style of military contracting from that which we see today.

Celab was asked to design and manufacture a power supply for use in a Jet Fighter, which supplies a total of 140W to avionics equipment from a nominal 28VDC supply. Discover the challenge faced and how Celab designed a fit for purpose power supply in this case study.

A custom power supply is the answer to many manufacturers’ power problems. If your design imposes a set of non-standard power requirements, then a custom power supply is what you’re looking for.

We live in a world where almost everything we use is powered by electricity. Raw electrical power sources can be mains alternating voltage, batteries, wind mill turbine output, solar panel output, batteries etc. In almost all cases a product designer will need a converter to transform the raw electrical power into an output compatible with the intended use. Power Supply manufacturers offer a wide variety of off-the-shelf converters for this purpose. However, there are many cases where this broad market offering will not suit the designer’s need.

An Uninterruptible Power Supply (UPS) is a device that provides emergency power when the main power supply fails. It kicks in instantly to avoid any blip in power and is often used with a backup generator. We look into both the advantages and disadvantages of having an uninterruptible power supply.
