DESCRIPTION

 The SPDU is an equipment that distributes the 28 Vdc power to the aircraft loads and provides protection for their wiring. The SPDU can receive its input power from multiple sources and controls the loads based on the commands received through the data bus. The SSPCs can be commanded ON, OFF or reset through the data bus. The status of each load and the switch can be interrogated through the data bus. The SSPCs provide combined switching for the load and protection for the wiring.Lightweight, approximately 6.75 lbs.
NOTE: Assemblies can be configured and qualified to customer-specific requirements. Contact your Leach International sales representative for further information.
