The Von Duprin PS902-2RS power supply provides clean, regulated 12/24VDC power for electric latch retraction (EL/QEL) devices, electric strikes, and magnetic locks. Field selectable voltage — flip the switch for 12V or 24V. Mounts in a standard electrical box or on a backboard.
Every access-controlled door needs a power supply. The Von Duprin PS series is purpose-built for exit device electronics — the output is clean enough to avoid solenoid chatter and false triggers that cheap power supplies cause.
Pro-Tip from Our Locksmiths: Size your power supply for the TOTAL load on the circuit, not just one device. A single QEL exit device draws about 2A at 24VDC during latch retraction. If you're powering two QEL devices off one supply, you need the PS914 (4A) minimum, not the PS902 (2A). Undersized power supplies cause slow latch retraction and premature solenoid failure.
