Aero specialties manufactures jetgo 28 5v dc diesel electric hybrid aircraft ground power units gpus in the united states.

Ground power unit aircraft function.

Ground power units usually consist of a generator powered by a diesel engine but may found in other configurations. A ground power unit gpu can be either a fixed or mobile unit which can be connected to the electrical system of an aircraft while on the ground to provide either 120v ac or 28v dc power. They do this by supplying either 28 5v dc or 400hz power to aircraft parked at a gate or at a hanger. A gpu can refer to a dedicated electric power supply battery power supply or a combination of both.

Aircraft ground power units gpus are used to supply power to aircraft when they are on the ground and to aid in starting aircraft engines. Auxiliary power unit apu. Ground power units usually provide either. Aircraft apus generally produce 115 v alternating current ac at 400 hz rather than 50 60 hz in mains supply to run the electrical systems of the aircraft.

When gpus are not properly maintained the results can be both dangerous and extremely expensive. A ground power unit is a vehicle capable of supplying power to aircraft parked on the ground. Ground power unit gpu are a central part of an airport s ground handling operation and aircraft function. Gpus are a vital part of ground support equipment and proper maintenance and inspection is key.

There s also a kind known as an aircraft ground power unit. Ground power units are available in a variety of configurations and power capacities. A gpu much unlike your average household power supply is unique in that it provides a very specific ripple free or clean voltage this ensures sensitive avionics and control systems within the aircraft are. Others can produce 28 v.
