Lifesafety Power FPO150/250-C8D8E4 Redundant Power Supply
Overview
The FPO150/250-C8D8E4 is a dual-output redundant power supply designed to eliminate single points of failure in security and access control deployments. This unit delivers simultaneous, independent power to two circuits—a critical architecture for mission-critical surveillance, door control, and alarm systems where downtime is unacceptable. Redundancy is not optional in warehouses, data centers, or facilities with high-occupancy loads; this supply enforces it at the power layer.
Specifications and Deployment Benefit
Output Configuration: The unit is designated C8D8E4, indicating dual 8-amp channels with battery supervision and auxiliary power outputs. Dual independent outputs mean one circuit failure does not cascade to the second—each output is isolated and can be load-balanced across different subsystems (e.g., one channel to cameras, one to door locks or access panels).
Input and Supervision: Accepts standard AC mains input and supports supervised battery backup circuits, enabling graceful fallback to battery power in the event of AC loss. Battery supervision ensures the system operator is immediately alerted to battery depletion or degradation, preventing silent failures during extended outages.
Form Factor: DIN-rail mountable industrial enclosure, standard in commercial security cabinets and control rooms. This form factor simplifies integration into existing rack architectures and reduces real-estate footprint.
Installation Notes
Verify AC mains availability at the installation site (typical 110–240V, region-dependent). Plan battery backup capacity based on load profile and required runtime; oversizing the battery by 20–30% is standard practice to account for charge cycle degradation. All output terminals require proper strain relief and labeling—use of wire ferrules on 8 AWG and smaller conductors is mandatory per NEC Article 110. Commission the unit with a load analysis to confirm balanced distribution across channels.
When to Choose a Different Model
If your deployment requires more than two independent circuits, or if total load exceeds 16 amps aggregate capacity, evaluate higher-capacity or multi-channel variants within the Lifesafety Power family. Single-output supplies are not appropriate for redundancy-critical applications.
