Lifesafety Power FPO75-C4E1 4-Door Access Control Power Supply
Overview
The FPO75-C4E1 is a 75W power supply purpose-built to drive four independent access control lock outputs from a single enclosure. Each of its four outputs is individually fused at 3A and rated for 6A@12V or 3A@24V — meaning you can run four electromagnetic locks, solenoids, or relay-driven devices independently without a single overloaded output shutting down the rest of the system. Mounted in a compact E1 enclosure, it integrates directly into door access control cabinets, card reader wiring closets, and multi-door credential systems where you need distributed power without sprawling individual supplies.
Compatibility
The FPO75-C4E1 outputs standard 12V or 24V DC on screw terminals, making it compatible with any access control system that uses discrete lock outputs — card readers with relay cards, networked access control panels, and legacy hardwired door controllers. Verify your panel's output voltage requirement (12V or 24V) and total amperage draw before selection; the per-output 3A fuse limit is hard, so a single door's solenoid or mag lock draw cannot exceed 3A without nuisance trips.
Installation Notes
The E1 enclosure is DIN-rail mountable or surface-mount capable. Input power is 120VAC or 240VAC (confirm your building supply); output is screw-terminal 12V or 24V DC. Four separate fused outputs allow you to wire each door independently without shared ground loops — critical in noisy electrical environments. Ensure the access control panel's relay outputs are rated for the FPO75-C4E1's input voltage, and verify that total lock amperage across all four outputs does not exceed 75W (approximately 6.25A@12V combined or 3.1A@24V combined).
