Altronix AL176UL Power Supply

The Altronix AL176UL is a proprietary power supply and charger delivering 12 VDC or 24 VDC at 1.75 A. It is designed for security and access-control installations that require a Class 2 power-limited output. The unit operates from a 115 VAC input and carries cULus listing to UL294 for regulated applications.

Enclosed Chassis and Wiring Access

The supply ships inside a metal enclosure measuring 8.5 in high, 7.5 in wide and 3.5 in deep. This form factor simplifies wall mounting and protects internal terminals, but installers must verify conduit entries align with the fixed knockouts. Battery monitoring leads are pre-wired, yet the AC input terminals accept only solid or stranded conductors sized for the 115 VAC feed.

Continuous Dual-Voltage Operation

Under sustained load the unit maintains either 12 VDC or 24 VDC output without switching between rails, and the Class 2 limit prevents the output from exceeding safe energy levels during fault conditions. Continuous AC and battery monitoring circuits draw minimal quiescent current, so the charger maintains standby batteries indefinitely. The cULus listing confirms compliance for continuous duty in access-control systems.

Questions about this item

How do I confirm the ALTRONIX AL176UL is operating correctly after installation?

Verify the green AC LED is lit, the battery LED shows a healthy charge, and measure 12 or 24 VDC at the output terminals with a multimeter under load.

What comes in the box and what must I purchase separately for the AL176UL?

The unit ships in its 8.5inH x 7.5inW x 3.5inD enclosure; you must supply a 115VAC feed, a 12V or 24V backup battery, and all field wiring.

Should I configure the AL176UL for 12VDC or 24VDC output for my access-control system?

Match the supply to your panel's voltage requirement — 12VDC for most standard readers and locks, 24VDC for longer wire runs or devices rated for 24V.
