Airfield rectifier AR-800A-400Hz

AR-400hzAirfield rectifier AR-800A with 400Hz input is designed for use on AC ground power units to supply 28V DC to aircrafts and helicopters. It is also can be used as a power unit of test benches, hangars and aircraft manufacturing plants.

The rectifier can be power supplied by any type of 400Hz 200V converter (50/60Hz based units also available):

– Diesel generators
– Static frequency converters

The rectifier is designed to supply 800 A continuous output and 2500 A soft engine start. The rectifier is available in mobile and stationary version.
