Ground Power Units | Planet GSE

Ground Power Units


When parked on the ground an aircraft cannot use the normal 50Hz (or 60Hz in America) mains power as it needs 400Hz power. As a result airports need specialised ground support equipment (GSE), also known as ground power units (GPUs), to allow the aircraft to function whilst on the ground. Our compact dimensioned frequency converters can be fixed to the gantry of a passenger loading bridge or can be hung underneath the walkway or simply fixed to a convenient place close to the aircraft.

The advantage of these GSEs is that it prevents the on board turbo generator APU being run which produces a lot of noise and air pollution. Our ground power unit is connected to the normal 3 phase mains power source and delivers an output of 200V 3 phase 400 Hz power to the aircraft through a special flexible cable. The converter is only switched on when the aircraft needs the power, it also has a built in feature that allows the converter to synchronise with the on board aircraft power system so the lights, air conditioning system and the avionics continue operating during the change over from aircraft power to the external converter power.
