FAQ

Power rating

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

Interlock

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.
