Altronix T2M7XK2D Integrated Power Supply, Battery Backup, and Access Control Enclosure
Overview
The Altronix T2M7XK2D is a consolidated power and access control platform designed for mid-to-large commercial security deployments where running separate power supplies, battery backup units, and access control hardware would otherwise require multiple enclosures and significant wiring overhead. It accepts 120VAC/60Hz input, delivers regulated 12VDC at 6A continuous and 24VDC at 10A continuous, houses four 12VDC/7AH batteries for a total of 28AH of standby capacity, and incorporates an access controller with PTC-protected outputs — all within a single 27.25" x 21.5" x 6.5" steel enclosure. A 6.3A/250V input fuse protects upstream wiring. For integrators working with Altronix power and access solutions, this platform consolidates what would otherwise be a multi-box installation into a single, inspectable cabinet.
Key Features
- Dual regulated outputs (12VDC/6A + 24VDC/10A): Powers both 12V camera infrastructure and 24V access control readers or locks from one supply. The 10A continuous 24VDC rail handles multiple mag-locks without a dedicated booster — meaningful on a 4–8 door system.
- Four internal 12VDC/7AH batteries (28AH total): All four batteries sit inside the enclosure, eliminating the external battery cabinet that most comparable systems require. At typical access control loads, this provides several hours of standby — verify against your specific draw before commissioning.
- PTC-protected distribution on every output rail: Input power distribution runs 2.5A PTCs; the access controller output runs 2.5A PTCs with a 9A controller input. PTCs reset automatically after a fault clears — no blown fuses to swap during a 2AM service call.
- 1A unswitched auxiliary output: Available for auxiliary devices that need continuous power regardless of the main system state — door position sensors, REX devices, or panel tamper circuits.
- CE-listed enclosure: Meets European Conformity requirements, relevant for enterprise buyers with cross-jurisdiction compliance obligations on panel hardware.
- Sixteen conduit knockouts (1/2" and 3/4") + one 2" knockout: Enough knockout positions to run separate conduit for power, data, and reader wiring without sharing conduit — a real-world installation detail that simplifies AHJ inspections on access control panels.
- Operating range 0°C to 49°C: Suitable for conditioned mechanical rooms and IDF closets. Not rated for unconditioned outdoor enclosures — plan accordingly if your termination point is an exterior pedestal.
Integration & Compatibility
The T2M7XK2D is designed for integration within commercial access control systems where both power and controller functions are consolidated at the door controller level. The access controller accepts 24VDC input and provides selectable 12VDC or 24VDC output to downstream readers and locking hardware — check your specific reader and lock specifications against the 2.5A per-output PTC rating before finalizing your design. The 24VDC/10A voltage regulator rail can also serve as the distribution point for PoE mid-spans or auxiliary security power supplies in an expanded installation. Heat dissipation is rated at 145 BTU/Hr — factor this into cabinet thermal planning when installing in a sealed enclosure room. The shipping weight of 45.6 lb (product weight 41.6 lb) warrants a two-person installation; wall-mount anchor points should be rated for the combined weight including batteries.
Frequently Asked Questions
Q: What is the total battery backup capacity of the T2M7XK2D?
A: The T2M7XK2D houses four internal 12VDC/7AH batteries, providing 28AH total standby capacity within the enclosure itself — no external battery cabinet required.
Q: What output voltages does the T2M7XK2D provide?
A: It provides 12VDC at 6A continuous and 24VDC at 10A continuous. The access controller output is selectable at 12VDC or 24VDC, both PTC-protected at 2.5A per output.
Q: What input voltage does the T2M7XK2D require?
A: It requires 120VAC, 60Hz input. A 6.3A/250V fuse protects the input. It is not designed for 240VAC or international mains voltage.
Q: What is the enclosure size and weight?
A: The enclosure measures 27.25" x 21.5" x 6.5" and weighs 41.6 lb (product weight). Plan for two-person installation and verify wall-mount anchor ratings before installation.
Q: Is the T2M7XK2D suitable for outdoor installation?
A: The operating temperature range is 0°C to 49°C. It is designed for conditioned indoor environments such as IDF closets and mechanical rooms — not rated for unconditioned outdoor pedestal installations.
Q: What is the heat output of the T2M7XK2D?
A: Rated at 145 BTU/Hr. Factor this into thermal planning for any sealed or low-ventilation equipment room.
The T2M7XK2D is the kind of panel I recommend when an integrator is trying to eliminate the "enclosure sprawl" that plagues medium-density access control installations — you get your 12VDC/6A camera or peripheral supply, a 24VDC/10A regulated rail for readers and locks, four internal 7AH batteries, and the access controller itself, all pre-wired into one 27.25" x 21.5" cabinet. That 28AH internal battery stack is what separates this from a basic power supply combo.
Technical Highlights:
- 24VDC/10A Voltage Regulator: 10A continuous on the 24V rail supports multiple simultaneous mag-locks and card readers without a downstream booster — material savings on a 6–8 door deployment.
- PTC-Protected Outputs: 2.5A PTCs on both the input distribution (24VDC) and the access controller outputs (12 or 24VDC) reset automatically after fault clearance — no fuse replacement on callback visits.
- 145 BTU/Hr Heat Output: Not trivial in a sealed telecom closet. A room running multiple panels like this one needs active ventilation or a thermal load calculation before final placement.
Deployment Considerations:
- At 41.6 lb with four internal batteries, this is a two-person wall-mount — pre-install the backplate and confirm anchor pull ratings before the batteries are inserted.
- The 0°C to 49°C operating range means this panel cannot be installed in an unconditioned exterior pedestal or unheated utility space in cold climates — a common oversight on perimeter access control projects.
This platform is best suited for mid-size commercial buildings — corporate lobbies, healthcare facilities, or education campuses — where a facilities team wants a single, inspectable panel per floor or zone rather than distributed individual power supplies spread across multiple closets.
