Optimum electrical power distribution management

At the heart of the aircraft's electrical system, the PEPDS (Primary Electrical Power Distribution System) enables you to concentrate the energy produced by all the power sources available on the aircraft. It thus guarantees the availability of the electricity supply for the entire network, the operation and protection of all the aircraft's systems. Safran Electronics & Defense also provides you with an SPDS (Secondary Power Distribution System) supplying power to equipment that can be switched on or off depending on the stage of the flight, such as interior and exterior lighting or the cabin air management system.

Presentation

To manage the electrical power distribution, Safran Electronics & Defense collects the various sources of power available on aircraft:

  • main generators
  • auxiliary generator
  • back-up generation system
  • main battery
  • ground-based generators
