Altronix T2M7LCK3D 12/24VDC Access Control Power Supply with Battery Backup
Overview
The Altronix T2M7LCK3D is a hardened, UL294-listed access control power supply designed for commercial and institutional deployments where uninterrupted door control is non-negotiable. Drawing 4.2A max from a standard 115VAC/60Hz circuit, it converts to 12VDC and/or 24VDC at 6A continuous — enough sustained output to drive multi-reader configurations or a mix of electromagnetic locks and electrified strikes without tripping a branch circuit breaker. The enclosure accommodates four 7AH/12VDC batteries, giving you 28AH total standby capacity in a single chassis for extended power holdover during a grid outage. If your project spec requires UL294, CAN/ULC S319-05, or CE European Conformity, this unit ships with all three listings in evidence.
This unit targets mid-to-large access control installs: multi-door commercial buildings, institutional facilities, or warehouse perimeters where a mix of 12VDC and 24VDC field devices share a single power zone. The T2M7LCK3D handles that dual-voltage requirement directly — no secondary power supply, no splitter panels required.

Key Features
- 6A Continuous Output at 12VDC and/or 24VDC: Sustained 6A means you're not stealing headroom from other loads as devices cycle on. Multi-voltage output lets a single power zone serve both 12VDC magnetic locks and 24VDC electrified hardware without a separate converter in the field.
- 28AH Total Battery Capacity (4 × 7AH): Four 7AH batteries housed within the enclosure deliver substantial holdover time during power loss — critical on UL294-listed systems where doors must fail-secure or fail-safe per spec for a defined duration. More AH means more time before a building access event becomes a security event.
- 115VAC/60Hz Input, 4.2A Max Draw: Pulls under 4.2A from a standard 15A circuit, so it fits cleanly into a typical panel knockout without a dedicated 20A home-run. Multiple units can share a circuit in smaller facilities where panel space is tight.
- UL294, CAN/ULC S319-05, CE Listings: UL294 is the access control power supply standard in the US — required on most commercial projects and specified by most AHJs. CAN/ULC S319-05 covers Canadian installations. CE covers European deployments. One SKU clears three jurisdictions.
- 0°C to 49°C Operating Range: Covers standard conditioned interior environments from cold utility rooms to warm equipment closets. The -20°C to 70°C storage range means it survives warehouse staging and transport without damage to internal components.
