Point Of Use Ground Power – Lean, Mean & Green

The SD40 M series mobile frequency converters from Power Systems International Ltd are designed to replace the traditional, noisy, air polluting diesel engine driven 400Hz GPUs with the latest design in solid state frequency converters.

The SD Series produces a high stability 400Hz output and can simply be plugged into the normal 50Hz or 60Hz mains power source. The product will accept a wide variation in input voltage and frequency and utilise the latest in IGBT power conversion PWM inverter switching technology to provide 400Hz power for all types of passenger aircraft, helicopters and military aircraft with an extremely flexible, cost effective, energy efficient “point of use” aircraft ground power system for indoor and outdoor applications.

The users of the familiar, traditional diesel engine driven GPU’s will recognise the obvious benefits of using an all electrical SD 40M GPU: no combustion smells, smoke, fumes, toxic emissions, air pollution, fuel storage / spillage / bills and no engine start battery or engine maintenance costs.
