Keep critical doors and security devices powered with the Altronix AL400ULACMCB. This wall-mount power supply converts 120 V AC input into 12 VDC at 4 A or 24 VDC at 3 A, with eight independently controlled, Class 2 rated, power-limited outputs. Each output is PTC protected to support reliable distribution across mag locks, electric strikes, and magnetic door holders. Designed for access control environments where uptime and controlled release matter, this unit supports fail-safe and fail-secure operation and includes an individually selectable fire alarm disconnect feature. That makes it a strong fit for installations that must support emergency egress without sacrificing day-to-day security. UL/CUL listing and CSFM approval add confidence for regulated projects, while the lifetime warranty reflects the durability expected in infrastructure-grade deployments. For teams comparing lower-cost supplies, the difference is in control and compliance. Eight protected outputs, selectable alarm disconnect, and dual-voltage operation reduce the need for extra hardware and simplify panel design. When the system has to perform under fault conditions, this model is built to do the job cleanly.
