Altronix MAXIMAL3RHD Access Power Controller with Power Supply Charger, PTC Relay Outputs, 12/24VDC at 6A, 115VAC, 2U

Ensure uninterrupted, centrally managed power for access control and security installations with the Altronix MAXIMAL3RHD Access Power Controller. Designed for professional security, the MAXIMAL3RHD combines a high-reliability power supply/charger and eight independently controlled PTC outputs that can be configured for 12V or 24V at up to 6A per output—ideal for mag locks, strikes and other door hardware. Each output supports selectable Fail‑Safe or Fail‑Secure operation and individual fire alarm disconnect (latching or non‑latching), giving integrators the flexibility to meet site-specific safety and code requirements.

With a built-in charger for sealed lead‑acid/gel batteries, instantaneous transfer to standby power, and comprehensive AC and battery supervision, this 2U rack-mount unit keeps surveillance, monitoring and access control systems online during outages. The MAXIMAL3RHD’s PTC protection provides thermal and short-circuit auto-reset protection to reduce service calls and protect sensitive equipment. NDAA compliant and designed for rack installations, it’s an efficient choice for enterprise security, parking control, and multi-door access systems. Contact your distributor or systems integrator to specify the MAXIMAL3RHD for your next project.
