Altronix SMP3E 12/24 VDC Power Supply

The Altronix SMP3E is a proprietary power supply and charger designed for electromagnetic locking systems. It delivers selectable 12 VDC or 24 VDC output at 2.5 amps from a single unit. The enclosure measures 8.5 inches high, 7.5 inches wide and 3.5 inches deep for wall mounting. This accessory suits installers who need a dual-voltage source for access-control hardware.

Installation notes and common issues

The unit mounts inside its metal enclosure using the provided hardware and connects to mains power via terminal blocks. Wiring the lock output requires selecting the correct voltage tap before energising the circuit. A frequent mistake is leaving the voltage selector on the wrong setting, which can prevent the lock from operating. Ensure the enclosure is grounded and that cable entry uses the supplied knockouts to maintain the rated protection.

Questions about this item

How do I verify the unit is delivering 12 VDC or 24 VDC at 2.5 amp after installation?

Measure the output terminals with a multimeter set to DC volts; it should read the selected voltage, and under load the current draw must not exceed 2.5 amp.

What comes in the box and what must I supply separately?

The enclosure measuring 8.5 inH x 7.5 inW x 3.5 inD with the power supply inside is included; you must provide the AC mains lead, output wiring and any mounting hardware.
