Lifesafety Power FPO150-B100C8D8E4S 150W Power Supply with Relay Control Outputs
Overview
The FPO150-B100C8D8E4S is a 150W supervised power supply designed for access control and life safety installations requiring multiple relay-switched load control. It delivers 12A at 12VDC or 6A at 24VDC from the primary input, with an adjustable 5–18V secondary output rated for 4A maximum. The unit supplies eight relay control outputs for magnetic locks, door strikes, or alarm signaling devices—each fused independently at 3A and user-selectable for fail-safe or fail-secure operation. Eight additional DC auxiliary outputs (also fused at 3A per channel) support dual-bus configuration (Bus1 or Bus2), enabling distributed power switching across access points without cascading single-point failures.
Compatibility
This supply integrates with security control systems and power infrastructure requiring Software House back-plate mounting and relay supervision. The eight-output control architecture supports multi-door access systems where individual lock circuits must isolate from one another for operational or safety reasons. Verify your control panel firmware and relay-assignment software support the B100C8D8E4S configuration code before ordering.
Installation Notes
The FPO150-B100C8D8E4S mounts in an E4 enclosure (24H × 20W × 4.5D inches). All relay and DC auxiliary outputs are fused at 3A per channel; validate that each load (lock solenoid, alarm relay, notification device) does not exceed 3A at rated voltage to prevent nuisance fuse operation. The adjustable secondary output permits field tuning to support legacy or non-standard auxiliary loads without separate power conditioning. Confirm enclosure thermal ventilation and ambient temperature (product operating range not specified in available documentation); consult the manufacturer if deployment environment approaches upper thermal limits.
