FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering. Proposed device comprises first electric generator driven by aircraft engine, aircraft onboard circuit fed from first generator, second generator driven by aircraft engine and engine electric circuit different from that of aircraft onboard circuit to supply engine equipment and its fittings. Engine circuit comprises constant current voltage distributing bus to supply electrical equipment, and power supply with its first input connected with aircraft onboard circuit and its second input connected with second generator to receive voltage therefrom, voltage converter connected with power supply second input, and communication circuit to feed voltage to voltage distribution bus from first input or from converter depending upon second generator voltage amplitude.
EFFECT: power supply for greater amount of electric equipment.
