Ground Power Unit, or GPU for short, is the name given to power supply equipment that provides clean power for both maintenance and engine starting aircraft that are on the ground.
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 protected during powered maintenance and engine starting operations.
The term “Ground Power Unit” can refer to a hybrid GPU power supply (typically diesel electric), battery powered GPU (such as lead-acid or lithium batteries) or a direct grid dependant dedicated power supply, generally found in large commercial airports.
Typically, Aircraft Ground Power Units provide 28V DC or 115V 400Hz AC, however START PAC manufacture GPUs for a wide range of applications, starting from super light 12V DC Lithium based right through to high output 400A Hybrid units. Our Lead acid, hybrid and lithium based starting units are trusted globally to provide reliable, clean power to private, military, mining and commercial application.
