Collins Aerospace's solid state distribution systems are the standard on numerous airplane platforms with over 2 million devices in service. Our systems are designed to provide power distribution functionality for the aircraft of today and tomorrow.

Our primary power distribution systems and secondary power distribution systems enable any electrically powered devices, such as window wipers, fans, pumps, galley and interior lights, to be controlled and protected. These remotely controlled solid state devices can be placed throughout the aircraft, eliminating components, reducing wiring, and lowering the weight and cost.

The reduction in weight contributes to aircraft fuel efficiency enhancement. In addition, aircraft manufacturers benefit from the significant reduction to the power distribution system's installation time. Fault detection within the system enhances the maintainability of the aircraft, making it easier for operators to identify and correct maintenance issues.

Solid state power module (SSPC)

Solid State Power Modules (SSPC) are programmable, maintenance-free and pluggable modules for electrical power distribution. SSPCs are used to save space in various areas of an aircraft and cover DC or AC applications along with digital and analog inputs for discrete data collection and processing. SSPCs combine different functions and offer a significantly increased reliability compared to electromechanical components. By their use, various aircraft functions may be executed automatically in the background, which significantly reduces the workload for the pilots and flight attendants. We currently supply our SSPCs to Airbus, Boeing, Bombardier, Embraer and Comac.

Remote power distribution unit (RPDU)

Remote Power Distribution Units (RPDUs) contain multiple SSPCs and can be deployed remotely at individual points on the aircraft. RPDUs are part of the secondary electrical power distribution system. Airbus, Boeing and Comac are currently supplied with our RPDUs.
