Lifesafety Power FPO250/250-2C8P4D8PE4M1 250W Power Supply Board
Overview
The Lifesafety Power FPO250/250-2C8P4D8PE4M1 is a 250W regulated power supply board engineered for distributed access control and security infrastructure. It delivers selectable 12VDC at 20A or 24VDC at 10A, making it suitable for powering multiple lock controllers, readers, and auxiliary devices in cabinet-based or distributed architectures. The board mounts inside 20W × 24H × 4.5D enclosures and accepts a Mercury or Lenel backplate, allowing direct integration into existing panel ecosystems without adapter hardware.
Output Architecture
The FPO250/250-2C8P4D8PE4M1 provides two independent output classes: 16 relay-switched lock control outputs rated at 2.5A per channel (class 2 power-limited), and 32 auxiliary DC outputs also class 2 power-limited at 2.5A each. This separation allows you to isolate high-inrush lock strikes from sensitive analog or digital auxiliary loads—reducing nuisance power resets and improving supervisory signal integrity across door and sensor circuits. Each output pair can be independently switched or latched, giving integrators granular control over strike sequencing and fail-safe behavior.
Compatibility
This board integrates directly with Mercury or Lenel control panels via its dedicated backplate adapter. It serves access control systems requiring distributed 12V or 24V power distribution, particularly configurations with multiple electric strikes, mag locks, IP cameras, and auxiliary sensors across a single building segment. Verify your existing panel supports this backplate form factor before ordering.
Form Factor and Installation
Compact footprint (20″W × 24″H × 4.5″D) fits standard electrical enclosures and wall-mounted panel applications. Door-mount option allows external positioning near load clusters, reducing voltage drop on long runs to remote strikes. Verify incoming AC supply capacity and ensure adequate clearance for terminal block access during commissioning.
