Optimum electrical power distribution management


The conditions under which military aircraft are used during operations are often extreme. The avionic equipment and sub-systems must have an optimum electrical supply, guaranteeing performance and safety.

With its Primary Electrical Power Distribution System (PEPDS), Safran Electronics & Defense concentrates the power produced by all the aircraft's available power sources and supplies the entire network. The Secondary Power Distribution System (SPDS) is used to supply electrical power to the equipment the crew wishes to be able to use on demand.
