What is a GPU?
To put it simply, Ground Power Units allow aircraft to function whilst they’re on the ground. For context, when they’re parked on the ground aircraft cannot use the mains power supply of 50Hz (or 60Hz in the USA). Instead, they require a supply of 400Hz power – a clever decision made by the Aviation industry to help them reduce the weight of each aircraft by significantly reducing the size of electrical components and motors.
Our Ground Power Units connect to the regular 3-phase mains power source of 50/60Hz and converts this into an incredibly stable output of 400Hz power that is usable for all types of aircraft, including passenger aircraft, helicopters, and military aircraft.
An essential part of Ground Support Equipment (GSE), our compact GPUs can be fixed to the gantry of a passenger loading bridge, hung underneath the walkway or even fixed to a convenient place nearby for easy access at all times.
Types of Ground Power Units We Supply
Discover our most popular GPU types below.
28vDC GPU
Mobile power supply systems designed for aircraft engine starting applications and the charging of onboard batteries. Split into three main categories, including the DD range designed for offshore installations, the PS range suitable for hangars and outdoor uses, and the SP range which is integrated into the 400Hz GPU.
400Hz GPU
Our most popular range of GPUs, these 400Hz frequency converters come in a range of formats. Including all-weather units designed for use outdoors in military airfields and airport applications, as well as fixed or mobile units to suit your logistical needs whatever the environment.
400Hz/28vDC GPU
Part of our SP Series, this Combi Unit is an extremely flexible Ground Power source designed for use in avionic workshops, aircraft maintenance hangars and test laboratories where compact dimensions are required.
