Lifesafety Power FPO75-B100E4M1 Dual Voltage DC Power Supply
Overview
The FPO75-B100E4M1 is a 75-watt, dual-voltage economical power supply engineered for distributed surveillance and access control infrastructure. Primary outputs deliver 6 amperes at 12VDC or 3 amperes at 24VDC, with a secondary 5–18VDC adjustable output rated at 4 amperes. This configuration supports mixed-voltage deployments — where IP cameras, door locks, and sensors operate at different nominal levels — without requiring separate power rails. The compact 20″ × 4.5″ × 24″ footprint fits standard 19-inch rack cabinets or wall-mount installations typical in warehouse automation and mid-scale security operations.
Compatibility
This supply integrates with any 12VDC or 24VDC endpoint ecosystem: analog and IP-based camera heads, solenoid locks, illuminators, and auxiliary sensors. The secondary 4-ampere output accommodates auxiliary control modules, relay cards, or low-power signaling circuits. In hybrid deployments combining PoE switch infrastructure (which handles powered network endpoints) with legacy 24VDC surveillance zones, the FPO75-B100E4M1 bridges both by consolidating non-PoE power distribution into a single enclosure.
Installation Notes
Verify load calculations before deployment: primary output is current-limited (6A @ 12V = 72 watts; 3A @ 24V = 72 watts combined). Secondary output shares total power budget. Confirm thermal environment — economical models prioritize cost over active cooling, so installer must ensure adequate cabinet ventilation or external airflow, particularly in warm climates or high-density rack deployments. Wiring termination is industrial-grade (input and output screw terminals); no field-replaceable fuses are mentioned in the specification.
