Altronix T2M7CK3D Dual-Voltage Access Control Power Center with Battery Backup

Overview

The Altronix T2M7CK3D is a dual-voltage, battery-backed power distribution center engineered for mid-to-large access control and surveillance installations where both 12VDC and 24VDC loads need to run from a single managed enclosure. It accepts 120VAC/60Hz mains and delivers 12VDC at 6A continuous on one rail and 24VDC at 10A on a second rail — enough headroom to run a full door controller array alongside a mix of locks, readers, and camera heads without juggling separate power supplies per zone. The T2M7CK3D ships with CE European Conformity listing, making it a viable option for installations that cross North American and European compliance requirements.

For integrators tired of tracking down which field power supply is causing a nuisance alarm at 2 a.m., the T2M7CK3D's dual Form C relay outputs for both AC fail and battery fail conditions give your monitoring system something actionable to work with — discrete contacts you can wire directly into an alarm panel or building management system.

Key Features

• 12VDC @ 6A Continuous Output: Delivers a steady 6 amps on the 12V rail — enough for a typical 4–6 door access control panel with electric strikes or mag-locks without hitting thermal rollback. Protected by a 6.3A/250V input fuse upstream, so a catastrophic short won't propagate back to your mains circuit.
• 24VDC @ 10A Second Rail: The 24V rail at 10A handles heavier loads like motorized locks, gate controllers, or 24V camera clusters. Input PTCs rated at 9A protect the source side, while the rail itself can sustain continuous 10A draw — useful on loading dock or parking gate installs where solenoid inrush is a real factor.
• PTC-Protected Outputs at 2.5A Each: Polymeric positive temperature coefficient (PTC) devices on each output reset automatically after a fault clears, eliminating the field call to replace a blown fuse at 3 a.m. The 2.5A per-channel ceiling also limits the blast radius of a single shorted device to that channel alone.
• 1A Unswitched Auxiliary Output: An always-on 1A auxiliary tap supports panel logic boards, request-to-exit sensors, or other low-current loads that must stay live even when main outputs are in a managed-off state — a detail that matters when your controller needs continuous power for memory retention during a lockdown event.
• Quad 12VDC/7AH Battery Backup (4 Batteries Onboard): Four sealed lead-acid or gel-type batteries mount inside the enclosure itself, providing 28AH total capacity at 12VDC — meaningful runtime on a lightly loaded system. The integrated low DC power shutdown circuit prevents deep discharge, which is the primary killer of SLA batteries in standby applications. Budget for battery replacement cycles accordingly; deep-cycle protection extends service life significantly.
• AC Fail and Battery Fail Form C Contacts: Both supervisory outputs present Form C (normally open / normally closed / common) contacts rated at 2.5A. Wire them to your panel's zone inputs for real-time mains and battery health visibility — not just a blinking LED on a wall box nobody checks.
• Operating Range 0°C to 49°C: Rated for ambient conditions found in IT closets, mechanical rooms, and secured utility spaces. Storage tolerance extends to –20°C to 70°C, so units can be staged in an unheated warehouse through winter without degrading the batteries before commissioning.
• Steel Enclosure — 27.25
