Altronix AL400ULX Single-Output 12/24VDC Power Supply/Charger, 4A/3A, BC300 Enclosure
The Altronix AL400ULX is a single-output power supply and battery charger that converts a 115VAC, 60Hz input into a selectable 12VDC or 24VDC Class 2 power-limited output. It provides up to 4A at 12VDC or 3A at 24VDC, supporting fire alarm, access control, intrusion alarm and other low-voltage security systems.
The filtered and electronically regulated DC output includes short-circuit and thermal-overload protection. A built-in charger supports sealed lead-acid or gel-type standby batteries and automatically transfers connected equipment to battery power during an AC failure.
AC-failure, low-battery and battery-presence supervision contacts support system monitoring. LED indicators provide visual status for AC input, DC output and battery conditions. The power supply is housed in an Altronix BC300 indoor wall-mount enclosure with combination conduit knockouts.
