Lifesafety Power FPO250/250-3D8P3M8NLCE12M 250W Managed Power Supply

Overview

The FPO250/250-3D8P3M8NLCE12M is a 250W power supply with selectable dual output (20A @ 12VDC or 10A @ 24VDC) designed for distributed security installations requiring individual output protection and bus selection. Eight class 2 power-limited DC auxiliary outputs, each fused at 3A and capable of 2.5A continuous per channel, enable modular expansion across dual supervision buses — critical for multi-zone deployments where output isolation and failover logic matter.

Compatibility

This supply integrates with Lifesafety Power managed distribution architectures and third-party security systems requiring independent output supervision and bus redundancy. The 8 outputs support simultaneous switching between Bus1 and Bus2 configurations, allowing deployment across physically separated access control, video, or alarm subsystems without a single point of failure. Each fused channel isolates downstream device failures and prevents cascade shutdown — essential when protecting IP cameras, door controllers, or sensor networks where one failed endpoint must not starve others.

Installation Notes

The FPO250/250-3D8P3M8NLCE12M includes an 8-port managed distribution module rated 3A per fused output. Select input voltage (12V or 24V) at provisioning; output voltage is fixed to that selection and cannot be field-switched. Dual bus headers accept independent supervision lines, permitting PoE switch-style monitoring and intelligent load shedding during brownout conditions. Mount the distribution module in a DIN-rail or wall-mounted enclosure with adequate airflow; thermal dissipation increases with output load and ambient temperature.
