Lifesafety Power FPO250-E4M 250W Regulated Power Supply
Overview
The FPO250-E4M is a 250-watt regulated power supply designed to distribute DC power across distributed security endpoints in medium-scale installations. Delivers either 20A at 12VDC or 10A at 24VDC—dual-voltage configuration eliminates the need to stock two SKUs when mixed-voltage deployments span IP cameras, access control readers, and auxiliary devices. The eight integrated relays enable remote supervision and status monitoring, critical when power infrastructure must remain transparent to the NVR or management platform.
Compatibility
The FPO250-E4M integrates into security systems requiring distributed 12V or 24V DC power. Typical deployment scenarios include wall-mount cabinet installations supporting multiple fixed-dome and turret camera feeds, access-control relay panels, and backup horn/strobe circuits. The Mercury backplate mounting hardware simplifies rack or enclosure integration in technical rooms where space efficiency matters. Verify your endpoint voltage (12V or 24V) before deployment—output is factory-configurable but not field-selectable.
Power and Relay Architecture
250W capacity translates to approximately 21 watts per IP camera in a 12-camera mixed infrastructure (assuming 12W baseline draw per endpoint plus headroom for peak inrush). Eight relay outputs provide switchable load control—useful for circuit isolation, UPS failover signaling, or relay-driven auxiliary loads. Confirmation feedback on each relay state supports supervisory integration with PoE switch management tools or access-control panels that monitor power bus health in real time.
Installation Notes
Verify AC input voltage availability (standard 110–240V universal input). Ensure adequate thermal clearance in the enclosure; the FPO250-E4M dissipates heat proportional to load draw. DC outputs are terminal-block wired; use 18–12 AWG conductors for runs under 50 feet to minimize voltage drop. Relay contact ratings support dry-contact signaling only—do not drive high-inrush loads directly without external contactors.
