The ALTRONIX-AL176ULB is a switching power supply board that converts a 115VAC input into a single, PTC protected 12- or 24VDC output.
The power supply is equipped with short circuit and thermal overload protection for optimal performance. The built-in battery charger works with sealed lead acid and gel type batteries. Following an AC power failure, the power supply automatically switches to backup battery power.
The unit has onboard LEDs that indicate AC input and DC output power status.
