Lifesafety Power FPO150/250-2C83D8E8M2 Dual-Output Power Supply with Relay Control

Overview

The FPO150/250-2C83D8E8M2 is a configurable power supply designed for access control systems requiring independent 12VDC and 24VDC distribution with integrated lock relay switching. It addresses the common integration challenge where a single power supply must feed multiple voltage domains — door strikes operating at 24V, magnetic locks at 12V, and auxiliary loads on separate buses — without additional external relay modules.

Specifications & Deployment

Output Capacity: Choose 150W (12A at 12V or 6A at 24V) or 250W (20A at 12V or 10A at 24V) depending on your lock and reader load. This eliminates undersizing errors in mixed-voltage installations.

Control Outputs: 8 relay lock control outputs, each fused at 3A and individually selectable for Fail-to-Lock (FAI), failsafe, or failsecure operation. This per-output configurability means you can deploy different logic to different doors on a single supply — critical when aesthetic and mechanical constraints demand varied locking profiles across the same entrance.

Auxiliary Outputs: 8 additional 3A-fused DC auxiliary outputs, each assignable to Bus 1 or Bus 2. These support powered readers, LED indicators, or magnetic sensors without consuming lock-control budget.

Form Factor: E8 metal enclosure (36H × 30W × 6.5D inches) suitable for equipment rack or wall mounting in secured electrical rooms.

Integration Context

This supply works within access control panel ecosystems where distributed switching and voltage isolation are non-negotiable. Verify compatibility with your controller's relay wiring protocol and current-draw scheduling before deployment. Confirm that your facility's backup power infrastructure (UPS or battery backup module, if required) is sized for aggregate lock and auxiliary load demands.
