Power Distribution And Management Systems

Primary power distribution systems (PPDS) and secondary power distribution systems (SPDS) enable seamless control and protection of all electrically powered devices, such as window wipers, fans, pumps, heaters and lights. Power distribution systems incorporate the use of solid state power controllers (SSPCs), which increase the reliability of the aircraft by eliminating lower reliability components. Unlike a centralized electric power distribution systems, distribution units that contain SSPCs can be distributed throughout the aircraft and remotely controlled, allowing them to be strategically located to minimize total aircraft wiring.
