Lifesafety Power FPO250/250-E2 Expandable Dual Voltage Power Supply
Overview
The FPO250/250-E2 is a 250W expandable dual voltage power supply rated for 20A at 12V or 10A at 24V output. The E2 enclosure form factor fits standard 19-inch rack deployments and wall-mount installations common in access control, alarm, and IP camera infrastructure. Dual voltage capability means a single unit can power 12V solenoid locks, card readers, and access control panels alongside 24V camera networks or sensor arrays—eliminating the need for separate single-voltage supplies in mixed-technology installations.
Compatibility
The FPO250/250-E2 is suitable for powering distributed surveillance and access control equipment that operates across 12V or 24V DC circuits. Common applications include powering IP camera PoE injectors, alarm panel backup supplies, door strike electromagnets rated for 12V, and 24V pan-tilt-zoom camera controllers. Verify your end-device voltage rating and current draw against the 20A (12V) or 10A (24V) output limits before integration. The expandable design allows stacking or daisy-chaining in multi-unit deployments for higher total amperage across facilities with multiple zones or buildings.
Installation Notes
Mount the E2 enclosure in a secure, climate-controlled location—typical indoor electrical closets or equipment rooms. Ensure input AC power matches the unit's input voltage specification and that branch circuit protection (breaker or fused disconnect) is sized appropriately for 250W maximum draw. Wire output terminals to devices using correctly gauged conductor for the maximum current draw (12 AWG or larger for 20A at 12V runs over 50 feet; consult NEC or local code for final sizing). Do not exceed rated voltage or amperage on individual output circuits; load-sharing across multiple devices is recommended for thermal management on extended 24/7 operation.
