Power converters

The SD40 M Series mobile frequency converters from Power Systems International Ltd are designed to replace the traditional, noisy, air polluting diesel engine-driven 400 Hz GPUs with the latest design in solid state frequency converters. The SD Series produces a high stability 400 Hz output and can simply be plugged into the normal 50 Hz or 60 Hz main 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 400 Hz 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.
