Installation Instructions Manual

Altronix LPS3AC is a linear power supply/charger designed for demanding security and access control applications. It converts low voltage AC input to a 12VDC/24VDC output with 2.5 amp continuous supply current and built-in supervision for AC fail. It features a selectable output voltage, filtered and electronically regulated output, thermal overload, and short circuit protection. Additionally, it has a built-in charger for sealed lead acid or gel type batteries, automatic switch over to stand-by battery, and fused battery protection.
