Lifesafety Power FPO75-B100C4E1-2SL1 75W Dual-Voltage Access Control Power Supply
Overview
The FPO75-B100C4E1-2SL1 is a 75W access control power supply designed for door lock and reader integration in commercial security installations. It provides simultaneous dual-voltage output (2A at 12VDC and 2A at 24VDC) from a single enclosure, eliminating the need for separate 12V and 24V supplies in multi-voltage access control systems. The four dedicated lock outputs allow direct connection of electric strikes, magnetic locks, or solenoid devices without intermediate relay modules, reducing panel clutter and wiring complexity. Compact form factor (14 × 12 × 4.5 inches) fits standard electrical cabinets and control rooms.
Compatibility
This unit integrates with access control systems requiring mixed-voltage door hardware — typical in enterprise deployments where different entry points use 12V readers paired with 24V locks, or vice versa. The two Salto Plates included facilitate mounting of Salto electronic lock cylinders and reader hardware. Verify your specific access control panel and lock specifications against the 2A per-rail current limits; higher-current locks (solenoids drawing >2A continuous) require external power distribution or additional supplies.
Installation Notes
Install in a DIN-rail or panel-mount enclosure with adequate ventilation; the supply dissipates heat proportional to lock duty cycle. Separate the 12V and 24V output rails to prevent ground loops in installations with multiple access panels. When wiring electric locks, confirm strike voltage specification before connection — reversing polarity on solenoid devices may cause coil damage. The four lock outputs should be load-tested during commissioning to verify adequate current margin under peak simultaneous activation (e.g., emergency egress scenarios).
