Altronix AL300ULPD4

The Altronix AL300ULPD4 is a multi-output power supply and charger that converts 115VAC/60Hz input into four independent 12VDC or 24VDC Class 2 rated outputs, each delivering 3.5A continuous current. Each output is filtered and electronically regulated with individual short-circuit and thermal overload protection, while the built-in charger accommodates sealed lead-acid or gel-type backup batteries with automatic switchover and zero voltage drop when AC power fails. AC fail, low battery, and battery presence supervision provide monitoring via Form C contacts for integration with security panels.
