Altronix T2AXK55F12PD 12VDC Access Control Power Supply with Battery Backup

Overview

The Altronix T2AXK55F12PD is a UL294-listed, 12VDC access control power supply and battery backup system designed for commercial security installations where code compliance and reliable continuous power are non-negotiable. Drawing 3.5A max from a standard 120VAC/60Hz circuit, it delivers 10A continuous at 12VDC to field devices — enough headroom to drive multiple door controllers, mag locks, or electric strikes from a single enclosure. The integrated 12AH/12VDC battery keeps connected devices live through a power outage without requiring a separate UPS unit.

If you're specifying power for a multi-door access control deployment, the T2AXK55F12PD positions as a self-contained power center: regulated DC output, PTC-protected distribution, and standby battery in one wall-mount enclosure. It's a practical fit for enterprise corridors, commercial office suites, or light industrial entry points governed by UL294 project requirements.

Key Features

10A Continuous Output at 12VDC: Provides sustained current to run multiple access control field devices simultaneously — mag locks, door position switches, request-to-exit sensors — without voltage sag that causes erratic locking behavior. Continuous rating (not peak) means this is the number you can plan around when sizing your load budget.

2.5A PTC-Protected Outputs: Positive temperature coefficient protection limits current on individual outputs if a device fault or wiring short occurs, resetting automatically without the technician needing to swap a fuse. Reduces field service calls caused by nuisance opens on overcurrent events.

12AH Onboard Battery Backup: The integrated 12AH/12VDC battery sustains connected loads through mains outages. At a modest 2–3A load (typical for two to four doors), you can calculate several hours of runtime — critical in facilities where access continuity during power events is a building code or insurance requirement.

120VAC/60Hz, 3.5A Input: Runs on a standard North American branch circuit with no special wiring. At 3.5A max draw, it occupies minimal amperage on a shared electrical panel — one dedicated 15A circuit comfortably handles multiple units if needed.

122 BTU/Hr Heat Dissipation: Factor this into equipment room thermal planning. At 122 BTU/Hr, a single unit is low-impact in a ventilated IDF closet or wall-mounted power room, but if you're stacking several in a confined enclosure, cumulative heat load requires attention during design.

Operating Range 0°C to 49°C: Covers unheated utility rooms and mild-climate equipment closets without thermal derating. Storage down to –20°C means the unit survives cold-chain warehouse conditions during shipping and commissioning.

UL294 / cUL (CAN/ULC-S319-05) / CE Listed: UL294 is the governing standard for access control equipment power supplies in the US — required by many AHJs for permit approval. The cUL listing extends code coverage to Canadian projects. CE marking satisfies European conformity for international installations. Bringing an unlisted power supply to a UL294-required project creates inspection risk; this unit eliminates that conversation.
