Altronix MAXIMAL55DV 12VDC 20A, 16 PTC Output, 220V Power Supply for Heavy-Duty Security Systems

Built for high-density access control and surveillance environments, the Altronix MAXIMAL55DV power supply delivers dependable power and intelligent control for up to 16 doors. This access power controller from Altronix converts 220VAC input into multiple 12VDC PTC-protected outputs, providing individual fault isolation and uninterrupted operation for mag locks, electric strikes and other security devices. Dual internal 12VDC supplies (9.5A each) provide robust capacity—up to a 20A aggregate—to handle high inrush loads while maintaining system stability.

The MAXIMAL55DV simplifies emergency response and monitoring with a built-in FACP interface and selectable fire alarm disconnect (latching or non-latching) on each output, plus support for fail-safe and fail-secure configurations. Housed in a secure BC800 enclosure and NDAA-compliant, it’s engineered for commercial and institutional installations where uptime and compliance matter. Ideal for integrators and security managers, this unit reduces rack space, streamlines cabling and enhances overall system reliability for access control, surveillance and safety monitoring. Upgrade your security infrastructure with the Altronix MAXIMAL55DV—engineered to power and protect mission-critical systems.
