AC Secondary Power Distribution

Secondary Power Distribution Unit


Distribute, control and protect using our 3-phase 115 VAC Secondary Power Distribution Unit (SPDU). This new electronic circuit breaker unit is capable of continuously delivering 180A across 24 independent SSPC outputs and replaces traditional circuit breakers and switching relays with industry leading solid-state performance, flexibility and safety.

Designed for all load types, the AC SPDU provides arc-fault protection and our patented fail-open protection while remaining compatible to MIL-STD-704 and DO-160 requirements for surge, in-rush currents and EMI / EMC. It also provides extensive redundancy, self-testing and maintenance logging to assure load and wire protection and provide troubleshooting tools. 

Customize for your application without software modifications. Using up-loadable data tables, remotely configure the SPDU to meet new performance requirements, add timing and control logic, support a wide-range of loads or quickly adapt to specific missions or optional detail packages.
