Altronix AL125ULB Access Control Power Supply Charger, 2 PTC Class 2 Outputs, 12/24VDC @ 1A, 24VAC, Board

The Altronix AL125ULB is a dual-output switching power supply and battery charger designed to convert a low-voltage AC input into two independently controlled outputs. Each output can be configured to deliver either 12VDC or 24VDC, providing flexibility for different system requirements.

Both outputs are equipped with PTC (resettable fuse) protection to help safeguard connected devices from overcurrent conditions, improving system reliability and safety. The unit is commonly used in security and access control applications such as powering cameras, electric locks, and other low-voltage devices.

In addition to power distribution, the AL125ULB includes battery charging capability, ensuring backup batteries remain charged for uninterrupted operation during AC power loss. Its compact and efficient design makes it suitable for a wide range of commercial and residential security installations.
