Lifesafety Power FPO250/250-3C85D8PE12M-WP-MAY01 Redundant Power Supply
Overview
The FPO250/250-3C85D8PE12M-WP-MAY01 is a dual-output, 2 × 250W redundant power supply designed for mission-critical surveillance and access control installations where uptime is non-negotiable. This unit delivers both 12VDC and 24VDC simultaneously from separate regulated outputs, eliminating single-point-of-failure risk in large camera arrays, door controllers, and distributed network equipment. The redundant architecture means one supply can fail while the second maintains full system power—critical in facilities where downtime translates directly to security gaps or operational losses.
Compatibility
This redundant power supply integrates with any 12VDC or 24VDC surveillance and access control system. Common deployments include multi-camera head-end installations, distributed PoE injector farms, commercial door strike and magnetic lock arrays, and modular network video recorder environments. Verify your system's total current draw across both rails before deployment—the dual 250W outputs support up to approximately 20A at 12VDC or 10A at 24VDC (combined load limits apply; check installation guide for dual-rail behavior under mixed loads).
Installation Notes
Install in a climate-controlled equipment cabinet or wall-mounted enclosure rated for industrial use. Ensure adequate airflow around the unit to prevent thermal stress during sustained full-load operation. Confirm input AC supply voltage matches the unit's rated input (typically 100–240VAC). Wire both positive and negative rails to their respective loads; do not mix 12VDC and 24VDC circuits on shared ground unless system design explicitly permits it. Test redundancy by disconnecting one input supply under controlled conditions to verify the second supply assumes full load without sag or alarm.
