Ground Power Unit (GPU) is the term given to equipment that powers, or starts, aircraft, whilst on the ground. A GPU can refer to a dedicated electric power supply, battery power supply or a combination of both. There's also a kind known as an aircraft ground power unit.  Ground power units usually provide either 28V DC or 115V 400Hz AC, although certain aircraft will require a more specialised power derivative. Powervamp is the only UK designer and manufacturer of ground power units ranging from the smallest 12V DC general aviation start unit to the hugely powerful PV90-4 400Hz frequency converter – already installed at a number of major international airports.
