The Altronix AL300ULXPD16 is a multi‑output power supply and battery charger that converts a 115VAC input into sixteen Class 2 power‑limited outputs selectable for 12VDC or 24VDC operation at up to 2.5A total current. Each output is fuse‑protected, electronically regulated, and protected against short circuit and thermal overload, making the unit suitable for access control, burglary, fire, and signaling applications. The unit features an integrated charger for sealed lead‑acid or gel batteries with automatic switchover to standby battery power during AC failure, zero voltage drop operation, and comprehensive supervision including AC failure, low battery, and battery presence monitoring via form “C” contacts. Visual LED indicators provide the status of AC, DC output, and battery conditions, and all components are housed in a BC400 steel enclosure designed for wall‑mount installation.
