Product Description
900-8P Von Duprin Power Supply Board — 8 PTC Auto-Resetting Outputs
Eliminate Service Calls: The 900-8P uses auto-resetting PTC outputs instead of glass fuses. When an output draws too much current — a shorted wire, a failing device — the PTC element heats up and cuts power to that output. Once the fault clears, it resets automatically. No driving back to a job site to replace a blown fuse after a power surge. On large installations with 8 devices, this board pays for itself the first time it saves you a service trip.
Same 8 output flexibility as the 900-8F, but with the convenience of self-resetting overcurrent protection. Plugs into any Von Duprin PS900 series supply. For fire alarm integration, get the 900-8P-FA.
