| 摘要 |
The invention concerns an electrical power supply device, in particular designed to be installed on board an aerodyne, supplying direct current to electric consumers (C1, C2,...Cn) from at least one power system (Rx) selected by a selector circuit (32) of the device, among a plurality of power systems (R1, R2,...Rn). The power supply device comprises an adaptor (A1, A2,...An) per power system (R1, R2,...Rn), each of the adaptors supplying, from the respective power system whereto the adaptor is connected, a pre-adjusted direct current voltage (V1, V2,...Vn), powering the electric consumers. The selection by the selector circuit (32), of the power system (Rx) and its associated adaptor (Ax) powering the consumers, being based on the pre-adjusted direct current voltage level of said adaptors. The invention is useful for powering equipment onboard an aircraft. |
