Power rating

Defined as the maximum output power the GPU can produce continuously under normal conditions.


Civil 400Hz: Once power is connected and activated to the aircraft, if the aircraft accepts the power it links a 28VDC signal to the F pin in the plug, the aircraft needs to receive the same 28VDC signal back on the E pin in the plug, this allows the aircraft to continue drawing power. The signal on E and F pins is also feed back to the GPU, this is used as confirmation that the GPU is supplying an aircraft.


For all engine related spare parts, maintenance and overhaul. We refer to the specific engine manufacturer’s local service representative, links can be found on the engine manufacturers official web site.
