DC Power Supplies | 28 VDC thru 600 FLA

FCX solid-state power supplies provide regulated 28.5VDC power with minimal noise. The power supplies are equipped with an adjustable current limiting feature for engine starting. Each model is designed with high power SCR modules to allow for precise control of the output voltage. The units also have soft start to allow the power supply to ramp to nominal output voltage. Power supplies are built in a mobile NEMA 3R equivalent enclosure for easy installation for interior and exterior environments.

Replacing Diesel Generators for the Patriot Missile System. Patriot Missiles, the defensive anti-missile system designed by Raytheon, are installed around the world to protect cities subject to missile attack. While utility power around the word is either 50 Hz or 60 Hz, the Patriot system incorporates several elements that require reliable 400 Hz power. Therefore, […]


Engineering Complex Power Supply for F-22 Test Program In the early 2000s, the engineering staff from Edwards Air Force Base (AFB) distributed an inquiry regarding a power supply for a 270 VDC military aircraft. FCX did not initially respond to the inquiry, however no viable solutions were presented by the 11 companies that did respond. […]


Powering F-35s Aboard Aircraft Carriers Anticipating the deployment of F-35 airplanes aboard aircraft carriers, the U.S. Navy issued a requisition for development of a system to feed power to 400 Hz AC and 270 VCD aircraft with a minimum impact on the existing equipment and space. FCX used its experience with the 400 Hz AC […]


Solid-State Frequency Converter for a Floating Dry Dock. In 2008, a large floating dry dock – containing motor loads for cranes, capstans, ballast pumps and fire pumps – was transported to the Grand Bahama Shipyard. The dry dock required 50 Hz power, while the Bahamas utilizes 60 Hz power. To supply the 50 Hz power […]
