COMING SOON!
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 your application without software modifications. Our exclusive Logic Designer System enables users to create customized, event driven behaviors to control SSPC and discrete outputs. Users can add timing and control logic, support a wide-range of loads or quickly adapt to specific missions or optional detail packages.
Reduce Aircraft Wiring
Using a distributed power control system greatly reduces the amount of wiring needed since each wire is not required to route to a centralized location. Reducing the wire runs simplifies installation, saves weight, and increases power system reliability.
Arc Fault Detection
Our technology solutions sensing capability can also be used to trip on intermittent arc faults produced by wire insulation failure. The arc fault sensing is designed to recognize the unique signature of an arc without tripping on turn-on transients from motors, lamps, etc. The ability to detect arc faults is an added feature that increases safety in aircraft power distribution and complies with new certification requirements.
Unique Failsafe Design
Unlike other solid-state products, the SPDU contains patented circuitry that prevents a failure in a short-circuited condition. This means that a failure will not cause a critical load to remain powered in an unprotected and uncontrolled manner.
