Altronix AL300ULXB2 Power Supply Charger, Single Class 2 Output, 12/24VDC @ 2.5A, 115VAC, Board

The Altronix AL300ULXB2 is a UL recognized power supply and battery charging unit designed to convert a 115VAC, 60Hz input into a single Class 2 rated, power-limited output of either 12VDC or 24VDC. It is commonly used in security, access control, and fire protection systems where reliable and regulated DC power is required.

This unit includes built-in monitoring features such as AC failure supervision, battery presence detection, and low battery supervision. These functions help ensure system reliability by providing alerts for power issues and maintaining proper backup battery operation.

Designed for safety and dependability, the AL300ULXB2 is suitable for applications that require consistent DC power delivery along with advanced system supervision capabilities for critical security infrastructure.
