Altronix AL400ACMCB220 Access Power Controller with Power Supply Charger, PTC Class Relay Outputs, 12/24VDC at 4A, FAI, 220VAC, BC400 Enclosure

Designed for mission-critical access control installations, the Altronix AL400ACMCB220 Access Power Controller delivers secure, reliable power and centralized management for up to eight doors. This Altronix power supply/charger converts 220VAC input to filtered, regulated 12/24VDC outputs (up to 4A aggregate), with eight independently controlled PTC-protected outputs to support both Fail-Safe and Fail-Secure locks. The built-in charger and instantaneous transfer to standby batteries ensure uninterrupted operation during power loss, improving system uptime for security, surveillance and monitoring applications.

Installation and system integration are simplified with a selectable Fire Alarm Interface (FAI) per output and an alarm relay that reports FACP status to central monitoring. Housed in a BC400 enclosure, the unit meets enterprise deployment needs while remaining NDAA-compliant and indoor-rated. By combining power, battery charging, and door control in a single package, the AL400ACMCB220 reduces rack space and wiring complexity, lowering total cost of ownership. Ideal for commercial buildings, campuses and critical infrastructure—specify the AL400ACMCB220 to streamline your next access control project.
