120kVA Trailer Ground Power Unit
When parked on the ground an aircraft cannot use the normal 50Hz mains power as it needs 400Hz power. As a result airports need specialized ground support equipment , also known as ground power units (GPUs), to allow the aircraft to function while on the ground. ACSOON compact dimensioned frequency converters can be fixed to the passenger loading bridge or can be hung underneath the walkway or simply fixed to a convenient place close to the aircraft.
The advantage of the Ground Power Unit is that it prevents the on board generator APU being run which produces a lot of noise and air pollution. The ACSOON ground power unit is connected to the normal 3 phase power source and delivers an output of 200V three phase 400 Hz power to the aircraft through cables. The GPU is only switched on when the aircraft needs the power, it also has a built in feature that allows the GPU to synchronize with the on board aircraft power system so the lights, air conditioning system and the avionics continue running and operating during the change over from aircraft power to the external GPU.
GPU is very efficient, the converter is only switched on when needed and is more flexible than the earlier generation 400Hz systems on older airports that operate large converters in parallel drawing continuous power from the mains.
ACSOON can also provide a combination system in a single enclosure with a 3 phase 200V 400Hz output and with a secondary output of 28V DC 600Amps with peak of 2000A for helicopter engine starting and battery charging that can be installed in a maintenance hangar or on the apron of an airport, the combination unit can also be built in the horizontal format for mounting under the passenger loading bridge and operate in conjunction with an automatic cable reeling unit.
The 90kVA, 120kVA and 180kVA systems can be supplied in outdoor or indoor enclosures with all weather protection for fixed or mounted on a trailer for mobile applications.
