Lifesafety Power FPO75/150-E2 Expandable Power Supply
Overview
The FPO75/150-E2 is a dual-voltage access control and surveillance power supply designed to feed mid-scale security systems — door locks, readers, cameras, intercoms — from a single source. Base configuration delivers 75W (6A at 12V or 3A at 24V); expansion modules push output to 150W (12A at 12V or 6A at 24V). The E2 enclosure houses the supply and protects all internal components from physical damage and minor environmental exposure, a critical requirement in electrical closets and equipment rooms where vibration, dust, and incidental moisture are real.
Compatibility
The FPO75/150-E2 works with any 12VDC or 24VDC load: electromagnetic locks, card readers, buzzer/alarm circuits, IP cameras pulling under the rated amperage, and intercom systems. Verify your total connected load (sum all device current draws) against the 75W or 150W capacity before installation. If you're running a 4-door access control system plus a pair of 5MP cameras, you'll likely need the full 150W configuration. Check individual device specs for exact current requirements at your chosen voltage.
Installation Notes
Wire the FPO75/150-E2 to a dedicated 120VAC or 240VAC circuit (check the label for input voltage — do not assume). Use appropriate gauge wire (consult local electrical code and the supply's input wiring diagram). Mount the enclosure in a climate-controlled space if possible; outdoor or uninsulated areas expose the transformer and capacitors to temperature extremes and moisture, shortening service life. Ensure adequate ventilation around the enclosure — blocked vents force internal heat buildup and thermal shutdown. Label all 12V and 24V outputs clearly to prevent wiring errors in the field. If you're daisy-chaining cameras or locks, calculate voltage drop over cable runs longer than 100 feet; thin wire stretches across large buildings causes under-voltage at the load.
