Aircraft ground power supply

net powersafe covers the entire range of reliable aircraft ground power supply, thereby contributing towards smooth operations for aircraft handling. 

For power supply to aircraft on the ground, we provide 115 V/200 V 400 Hz units for the cockpit and aircraft infrastructure. The frequency of 400 Hz for the on-board networks of commercial aircraft is selected because, at this level, the weight of electric generators, motors and devices is up to ten times lower than at the typical network frequencies of 50 Hz or 60 Hz. In ground-power operation and during maintenance work, the 400 Hz cable with a plug connector represents the umbilical cord that helps with implementing the operation and testing of all electric and electronic on-board functions. 

The technology range includes static and rotary 400 Hz converters that permit either stationary or mobile use. The ground power unit (GPU, a generating set with a combustion motor and a special 400 Hz generator) placed next to the aircraft is part of the traditional aircraft handling carried out by ground handling companies. 

For smaller aircraft, we recommend static and rotary 28 VDC converters for stationary or mobile use.
