Altronix Maximal75D Access Power Controller w/ Power Supply Chargers, 16 PTC Class Relay Outputs, P/S 24VDC at 9.7A and P/S 12VDC at 9.5A, 115VAC, BC800 Enclosure

Ensure uninterrupted operation of multi-door access systems with the Altronix Maximal75D Access Power Controller. Built for professional access control and security integrators, this unit delivers centralized power distribution and intelligent monitoring for up to 16 doors. With 16 PTC-class relay outputs and dual DC supplies (24VDC at 9.7A and 12VDC at 9.5A) fed from a 115VAC input, the Maximal75D supports mixed device environments—mag locks, electric strikes and magnetic door holders—while offering Fail-Safe and Fail-Secure operation options.

Designed to reduce service calls and simplify system management, the controller includes AC supervision, battery monitoring and thermal/short-circuit auto-reset protection. The FACP interface provides emergency egress and alarm monitoring for integrated security and life-safety workflows. Housed in a secure BC800 enclosure and NDAA-compliant, the Maximal75D is ideal for commercial, institutional and multi-tenant installations where reliability and code compliance matter.

Upgrade your security power distribution to a purpose-built solution that streamlines installation and enhances monitoring for surveillance and access control systems. Contact sales or order the Altronix Maximal75D for your next project.
