Altronix T1AA3CK1 12VDC Power Supply with Battery Backup Enclosure
Overview
The Altronix T1AA3CK1 is a UL294-listed, 12VDC power supply and battery backup system pre-wired for IC4 integration — purpose-built for commercial access control and surveillance installations that cannot tolerate a power interruption. Housed in a steel enclosure sized at 18" x 14.5" x 4.62", this unit accepts 120VAC/60Hz input and delivers a continuous 6A at 12VDC, with two internal 7AH/12VDC batteries providing standby runtime when AC fails. If your jurisdiction requires UL294 or CAN/ULC-S319-05 compliance for access control power, the T1AA3CK1 meets that bar out of the box.
Key Features
- 6A Continuous Output at 12VDC: Sustained 6A means you can power multiple card readers, door controllers, and associated peripherals from a single supply without derating concerns — no need to split loads across two separate supplies in most mid-size door deployments.
- Dual 7AH Internal Batteries: Two 7AH/12VDC batteries fit inside the enclosure, giving you meaningful standby runtime without an external battery cabinet. For a 2A load, expect roughly 6–7 hours of backup — enough to cover extended power outages in most commercial buildings.
- UL294 and CAN/ULC-S319-05 Listed: Both US and Canadian access control power listings are covered. Specifying authorities and AHJs in either country can accept this unit without additional agency review. CE marking also supports international projects.
- 5A/250V Input Fuse: The fused input protects the unit from upstream fault currents. A field-replaceable fuse means a blown fuse during commissioning or a surge event doesn't take the power supply out of service permanently.
- Pre-Wired for IC4: The IC4 pre-wire eliminates field wiring time on compatible Altronix access control platforms — connectors are terminated at the factory, reducing installation errors and commissioning time on multi-door projects.
- 0°C to 49°C Operating Range: Covers standard conditioned mechanical and IDF closets. Note this is not rated for unheated outdoor enclosures in cold climates — plan accordingly if the installation space drops below freezing.
- 90 BTU/Hr Heat Dissipation: At full load the unit dissipates 90 BTU/Hr. In a tight telecom closet or wall-mount enclosure, confirm adequate airflow — stacking multiple supplies in a sealed space without ventilation will exceed thermal limits.
Integration and Compatibility
The T1AA3CK1 is designed for deployment within Altronix access control and surveillance power ecosystems, specifically pre-wired for IC4-based configurations. It suits integration alongside commercial access control systems requiring a UL-listed 12VDC source. Pair it with compatible door controllers and consider your total door count and per-reader current draw when sizing — 6A continuous leaves reasonable headroom for a 4–8 door deployment depending on reader and lock selection. For larger installations, Altronix offers higher-current variants in the same family. Consult the access control power planning guide to calculate standby runtime against your battery and load budget. For panel-level integration, confirm IC4 compatibility with your chosen access control panel before ordering.
Frequently Asked Questions
Q: What agency listings does the T1AA3CK1 carry?
A: The T1AA3CK1 is listed to UL294, CAN/ULC-S319-05, and carries CE marking — covering US, Canadian, and select international access control power requirements.
Q: How many batteries does the T1AA3CK1 hold, and what capacity?
A: Two 7AH/12VDC batteries fit inside the enclosure, providing standby backup without requiring an external battery cabinet.
Q: What is the continuous output current of the T1AA3CK1?
A: The unit delivers 6A continuously at 12VDC from a 120VAC/60Hz input.
Q: Is the T1AA3CK1 suitable for outdoor or unheated enclosure installation?
A: No. The rated operating range is 0°C to 49°C, which covers conditioned indoor spaces. Unheated outdoor or cold-climate installs that fall below 0°C are outside the specified operating range.
Q: What does the IC4 pre-wire mean for installation?
A: The IC4 pre-wire means the unit ships with factory-terminated connectors for compatible Altronix IC4-based access control configurations, reducing field wiring time and the risk of wiring errors on multi-door projects.
Q: What is the enclosure size of the T1AA3CK1?
A: The enclosure measures 18" x 14.5" x 4.62". Shipping dimensions are 21.75" x 18.25" x 5.75", and the product weighs 18.0 lb.
The T1AA3CK1 is one of those units I recommend specifically when a project needs both UL294 compliance and dual battery capacity inside a single enclosure — the fact that it ships with two 7AH batteries already seated, and the IC4 pre-wire already done, is real time savings on a multi-door rollout where you're terminating a dozen of these in sequence.
Technical Highlights:
- 6A Continuous at 12VDC: Most 4–8 door access control deployments with standard readers and mag locks land well under 6A aggregate draw, so you get genuine headroom rather than running the supply at its ceiling all day.
- Dual 7AH Battery Capacity: Two batteries at 7AH each inside the same box means no auxiliary battery cabinet — useful when wall space in a telecom room is already spoken for. At a 2A sustained load, expect 6–7 hours of backup runtime.
- UL294 + CAN/ULC-S319-05: Dual-listed for US and Canadian jurisdictions — one SKU covers both sides of the border on multi-site enterprise projects without swapping supply models.
Deployment Considerations:
- Verify total connected load (readers + locks + ancillary devices) stays under 6A before commissioning — leaving at least 15–20% headroom is good practice for inrush on door unlock cycles.
- The 0°C lower operating limit is a real constraint: do not install in unheated mechanical rooms in northern climates where ambient drops below freezing, or battery performance and unit ratings are both compromised.
The T1AA3CK1 is the right fit for commercial office, healthcare, and education access control projects where a UL294-listed, battery-backed 12VDC source needs to live in a single wall-mount enclosure without consuming additional rack or cabinet space for battery expansion.
