AC Secondary Power Distribution



Distribute, control and protect using our 3-phase 115 VAC Secondary Power Distribution Unit (SPDU). This new aerospace and mil-spec 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.
