Lifesafety Power FPO250/250-4D8PE2 Dual Channel Power Supply with Auxiliary Distribution
Overview
The FPO250/250-4D8PE2 is a dual-channel power supply designed to deliver redundant DC power to networked security systems across distributed installations. This unit provides two independent 250W channels, each selectable for output at either 12VDC (20A) or 24VDC (10A), making it suitable for mixed-voltage camera deployments or facilities requiring failover-capable power infrastructure. The E2 enclosure footprint (20H × 16W × 4.5D inches) fits standard cabinet rails without sacrificing power density.
Key Specifications
Primary Output: Dual independent 250W channels—configure each for 12VDC at 20A or 24VDC at 10A depending on your powered endpoint requirements. This flexibility simplifies inventory when supporting both legacy 12V systems and modern 24V IP cameras in the same facility.
Auxiliary Distribution: Four 32A class 2 power-limited auxiliary outputs (2.5A per output, selectable per-output for Bus1 or Bus2 assignment). This segmented design isolates auxiliary loads (sensors, access control, supplemental lighting) from main camera power, improving fault tolerance and compliance with UL class 2 power-limited circuit requirements.
Dual-Bus Architecture: Each output can route to Bus1 or Bus2 independently, enabling you to partition loads across separate supervision circuits or distribute power to physically separated zones without requiring additional external relays.
Installation Context
Deploy this unit in central distribution hubs—server rooms, security control rooms, or rooftop utility cabinets—where you need to feed multiple remote power distribution nodes or directly terminate a mixed 12V/24V camera array. The compact enclosure height allows vertical stacking in space-constrained installations, and the class 2 auxiliary outputs support integration with third-party supervision systems without separate isolation transformers.
When to Choose a Different Model
If your installation requires integrated battery backup or single-channel output only, evaluate a smaller single-supply variant in the same Lifesafety Power family. If you need higher auxiliary current per output (beyond 2.5A) or more than four auxiliary ports, consider a larger industrial-rated supply with enhanced load distribution. Current availability is limited—backorder status applies; confirm lead time during procurement.
