The Primary Distribution System can be customized to Aircraft needs and can be built upon configuration. Safran Electrical & Power design Electrical Power Distribution Systems that feature high voltage and low voltage electrical networks, segregation and dissimilarity between essential and non-essential zones as well as centralized communication with the aircraft.

Global 7500 Emergency Power Distribution Box ("Emer" PC)

Emergency Power Distribution System

The emergency distribution aims at providing the aircraft electrical system with a safe alternative in case the main distribution is no longer supplied. It operates in direct link with main distribution and emergency generation sources such as battery or Ram Air Turbine (RAT). Depending on the application, the emergency distribution can be integrated in the main distribution box with the appropriate segregation or provided in a dedicated box.

Focus on the system’s key components

DC Module

The DC Module is an off-the-shelf solution designed with the objective to cover most aircraft and helicopter power distribution needs. It features an integrated Generator Control Unit (GCU) that can be easily tuned to most DC starter-generators.
