Electric power supply with high-level security, e.g. for electronic modules in aircraft

摘要

There is a device to supply electric energy to be used in an aerodyne feeder with a dc to electric consumers (C1-Cp) from at least one electric network (Rx). The latter is selected by a circuit selector (32) from amongst several networks (R1-Rn). There are adapters (A1-An) to supply preset dc voltage (V1-Vn). The selector circuit and its adaptor, which supply electric consumers, do so to the required voltage level.
