Altronix T1AA3CK1D 12/24VDC 6A Power Supply with Battery Backup

Overview

The Altronix T1AA3CK1D is a UL294-listed, dual-voltage power supply and battery charger housed in a 16-gauge galvanized steel enclosure — the kind of unit integrators reach for when a surveillance or access control installation demands reliable, code-compliant power with built-in battery backup. It accepts 120VAC/60Hz mains, delivers selectable 12VDC or 24VDC at up to 6A continuous across four output circuits, and holds two 7AH/12VDC batteries internally. For commercial power supply applications where uptime during a mains outage isn't optional, that onboard battery capacity is the critical differentiator.

The T1AA3CK1D is pre-wired for the IC4 enclosure configuration, which simplifies installation when you're dropping this into a structured panel assembly. If you're speccing power for a multi-device security installation and need a single enclosure that handles both regulated DC output and battery standby, this unit is sized appropriately for mid-density deployments.

Key Features

• 6A Continuous Output at 12VDC or 24VDC: Six amps continuous across the full output rail gives you enough headroom to power multiple cameras, locks, or readers simultaneously without tripping the supply into thermal limiting. Selectable voltage means one SKU covers both 12V and 24V device mixes — fewer part numbers to stock.
• Four Independent Output Circuits: Each output is rated at 28VAC or VDC @ 2.5A, letting you segment devices by zone or priority. Fault isolation on a single circuit doesn't take down the entire installation — a meaningful advantage in larger panel layouts where one shorted device would otherwise kill everything.
• Dual 7AH Battery Backup (14AH total): Two 7AH/12VDC batteries fit inside the enclosure, providing standby capacity without external battery boxes. At a typical 2–3A load, that's several hours of runtime during a mains outage — enough to cover most commercial contingency windows without an external UPS.
• UL294, cUL s319-05, and CE Listed: UL294 is the access control power supply standard; cUL s319-05 covers Canadian compliance. These listings are load-bearing for AHJ approval on commercial access control and intrusion installations — speccing an unlisted supply can hold up an inspection.
• 16-Gauge Galvanized Steel Enclosure: The enclosure isn't decorative — 16-gauge steel provides genuine physical resistance to tampering and meets the structural requirements expected in UL-listed panel assemblies. Galvanized finish resists corrosion in mechanical rooms and utility spaces where moisture is a factor.
• 5A/250V Input Fuse Protection: The 5A/250V input fuse protects upstream wiring from a catastrophic fault inside the supply. At 3.5A draw under full load, there's meaningful headroom before nuisance tripping — the fuse is sized to catch a real failure, not normal operating surges.
• Operating Range 0°C to 49°C: Covers the thermal envelope of conditioned mechanical rooms and IDF closets without derating. Storage down to -20°C means units can be staged in unheated warehouses without concern.

Integration & Compatibility

The T1AA3CK1D fits within the broader Altronix power and integration ecosystem and is pre-wired for the IC4 enclosure configuration. The four-output architecture pairs naturally with access control panels, door controllers, and IP cameras that require regulated DC power separate from their PoE infrastructure — particularly in installations where network closets are remote from door hardware locations. For multi-door deployments, pair this supply with a downstream fuse distribution module to further subdivide circuits. Consult your access control panel's power budget documentation to confirm load compatibility before speccing output circuit assignments. The dual-voltage output (12VDC or 24VDC selectable) makes this unit compatible with a wide range of reader hardware, electric strikes, and magnetic locks without requiring a separate step-down converter. For larger installations requiring more outputs or higher aggregate current, review the full access control power supply category for higher-capacity variants.

Frequently Asked Questions

Q: What is the total battery backup capacity of the T1AA3CK1D?

A: The T1AA3CK1D holds two 7AH/12VDC batteries internally, for a total of 14AH of onboard battery capacity. Actual standby runtime depends on connected load.

Q: Can the T1AA3CK1D output both 12VDC and 24VDC simultaneously?

A: The unit is selectable between 12VDC and 24VDC — it is not a split-rail supply outputting both voltages at the same time. Select the output voltage that matches your connected device requirements before installation.

Q: What agency listings does the T1AA3CK1D carry?

A: The T1AA3CK1D is listed to UL294 (access control power supplies), cUL s319-05 (Canadian equivalent), and CE. These listings are typically required for AHJ approval on commercial access control installations in the US and Canada.

Q: How many output circuits does the T1AA3CK1D provide?

A: It provides four output circuits, each rated at 28VAC or VDC @ 2.5A, for a total continuous output of 6A across all circuits.

Q: What input power does the T1AA3CK1D require?

A: The unit requires 120VAC at 60Hz, drawing up to 3.5A under full load. It is protected by a 5A/250V input fuse.

Q: What are the physical dimensions and weight of the T1AA3CK1D?

A: The enclosure measures 18 inches wide × 14.5 inches tall × 4.62 inches deep and weighs 16.23 lb., including the steel enclosure and internal components.
