Altronix T2AXK3F8SD Integrated Power Supply and Access Control Unit

Overview

The Altronix T2AXK3F8SD is a multi-function power and access control platform designed for commercial security installations where a single enclosure needs to consolidate AC-to-DC conversion, voltage regulation, power distribution, and access controller functions. Drawing 120VAC/60Hz at 3.5A max, the T2AXK3F8SD delivers 24VDC at 6A continuous — enough headroom for multi-reader door control systems paired with electric locks, REX devices, and credential readers, all fed from a single panel. If you're building out a mid-size access control infrastructure and want to avoid separate power closets for each subsystem, this is the product category to evaluate.

Key Features

• 24VDC at 6A Continuous Output: The primary power supply converts 120VAC/60Hz (3.5A max draw) to a regulated 24VDC rail delivering 6A continuously — enough to drive multiple electric strikes or magnetic locks simultaneously without voltage sag. Continuous-rated current matters on access control panels where inrush from multiple locks activating simultaneously can trip undersized supplies.
• Integrated 12VDC Voltage Regulator (6A Continuous): An onboard regulator accepts the 24VDC bus and steps it down to 12VDC at 6A — eliminating a separate 12V power supply for credential readers, door controllers, or auxiliary devices that operate on 12V. Having both rails inside one enclosure simplifies wiring and reduces cabinet clutter.
• Power Distribution Module — Dual Voltage: The distribution module accepts both 24VDC and 12VDC inputs and delivers either 12VDC or 24VDC outputs at 2.5A per output. This means individual field devices can be fed at the correct voltage directly from the panel, reducing field wiring runs and allowing per-circuit PTC fusing to protect each output independently.
• Integrated Access Controller (2.5A Output): The access controller section accepts 24VDC or 12VDC input and outputs either 12VDC or 24VDC at 2.5A — matched for powering electric locks and strikes at the voltage the hardware requires. Combining the controller and power in one chassis is standard practice in commercial access installs to reduce conduit runs and simplify commissioning.
• PTC (Polymeric Positive Temperature Coefficient) Protection: PTC fusing on outputs self-resets after a fault clears, unlike traditional fuses that require manual replacement. On a multi-door installation, a shorted field device won't leave a door permanently unpowered — the circuit recovers automatically once the fault is removed.
• UL294, CAN/ULC S319-05, and CE Listed: UL294 is the North American listing specifically for access control equipment — required for most AHJ (Authority Having Jurisdiction) approvals in the US and Canada. The CAN/ULC S319-05 listing covers Canadian installations. CE marking covers European conformity. A single product covering all three reduces paperwork on multi-site deployments that span borders.
