Altronix T1VK34D Integrated Access Control Power and Distribution Kit
Overview
The Altronix T1VK34D is a pre-integrated access control power kit built around a UL294-listed enclosure that combines a 24VDC/6A power supply, voltage regulation down to 12VDC, multi-output PTC distribution, and an access power controller — all wired and ready to accept up to two HID Aero or Vertx controller modules without external panel fabrication. If you're deploying a four-door HID-based access system and want a single, code-ready enclosure rather than a wire-it-yourself assembly, the T1VK34D is the targeted answer.
The 18" × 14.5" × 4.62" steel enclosure holds two 7AH/12VDC sealed lead-acid batteries in a 24VDC standby configuration — enough onboard reserve to satisfy UL294 hold-up requirements without sourcing a separate battery cabinet. For access control deployments where the AHJ demands listed power, that matters on day one of inspection.
Key Features
- 24VDC @ 6A Continuous Output: The power supply delivers 6 amps of continuous DC current at 24 volts — enough to drive two HID Aero or Vertx modules, associated readers, and door hardware simultaneously without approaching thermal cutback. Running at continuous-rated load, not peak, keeps the supply running cool over long duty cycles.
- Integrated 12VDC Voltage Regulation at 6A: An onboard voltage regulator steps the 24VDC bus down to 12VDC at up to 6A continuous, so you can feed both 12V and 24V door devices — electric strikes, mag-locks, readers — from the same enclosure without a separate brick or additional panel space.
- PTC-Protected Distribution Outputs at 2.5A: Both the power distribution module and the access power controller use 2.5A PTC (Polymeric Positive Temperature Coefficient) overcurrent protection per output. PTC devices reset automatically after a fault clears — no fuse replacement on a service call at 2 a.m. when a door strike shorts out.
- Four-Door Capacity in One Enclosure: The access power controller is rated for up to four doors, matching the HID Aero/Vertx module capacity of the enclosure. No split-panel provisioning, no secondary distribution box — all four doors draw from the same listed assembly.
- Dual 7AH Battery Standby in 24VDC Configuration: Two 7AH/12VDC batteries wire in series to produce 24VDC standby. Both batteries fit inside the enclosure, keeping the footprint tight and the installation self-contained. This eliminates the compliance risk of external battery cabinets that don't share the panel's UL listing.
- Relay-Rated Outputs at 28VAC/VDC @ 2.5A: The access power controller relays are rated at 28VAC or 28VDC at 2.5A — adequate for standard electric strike and mag-lock control. Verify your door hardware's inrush and hold current against this rating before specifying high-current mag-locks above 1.5A steady-state.
- UL294, cUL s319-05, and CE Listings: UL294 is the standard for access control units; cUL s319-05 covers Canadian installations. Having all three listings on a single enclosure simplifies AHJ approval in both US and Canadian jurisdictions and reduces the paperwork burden when submitting permit drawings.
- HID Aero/Vertx Module-Ready Mounting: The enclosure is pre-configured to accept up to two HID Aero or Vertx intelligent controller modules. If your site is already standardized on HID's IP-based access platform, the T1VK34D eliminates the custom backplane fabrication that otherwise consumes field labor hours.
- 0°C to 49°C Operating Range: The 49°C upper limit covers typical mechanical room and IT closet ambient temperatures in most commercial buildings. If your enclosure location sees sustained temperatures above that — think non-air-conditioned utility rooms in hot climates — confirm ambient before installing.
Integration and Compatibility
The T1VK34D is purpose-built around HID Global's Aero and Vertx intelligent controller family. The enclosure accepts up to two modules, which in HID's architecture translates directly to up to four doors using standard two-reader-per-module wiring. The power distribution module outputs 12VDC and/or 24VDC, allowing mixed-voltage door hardware on the same panel — a common scenario in retrofit projects where legacy 12V strikes coexist with newer 24V mag-locks.
The 28VAC/VDC relay rating on the access power controller outputs aligns with most standard commercial door controllers and electric locking hardware. Integration with HID's software platforms (SAFE, Symmetry, or third-party systems that support HID Aero/Vertx via SDK) is a function of the HID modules themselves — the T1VK34D provides the listed, protected power infrastructure those modules require.
For integrators sourcing the full Altronix access power line, the T1VK34D sits in the TROVE series, which is Altronix's pre-integrated kit product family designed to reduce field assembly time on HID-based systems. Pairing this unit with a listed access control power supply from the same series for larger deployments maintains listing continuity across the installation.
Frequently Asked Questions
Q: How many doors can the T1VK34D support?
A: The T1VK34D supports up to four (4) doors via its integrated access power controller, which aligns with the two HID Aero or Vertx modules the enclosure is designed to house.
Q: What batteries are included or required, and do they fit inside the enclosure?
A: The T1VK34D is designed for two 7AH/12VDC sealed lead-acid batteries wired in series for 24VDC standby. Both batteries fit within the 18" × 14.5" × 4.62" enclosure — no external battery cabinet required.
Q: What are the agency listings for the T1VK34D?
A: The T1VK34D carries UL294 (access control units), cUL s319-05 (Canadian equivalent), and CE listings, supporting installations in US and Canadian jurisdictions.
Q: Can the T1VK34D power both 12VDC and 24VDC door hardware simultaneously?
A: Yes. The integrated voltage regulator outputs 12VDC at up to 6A, while the power supply and distribution module also provide 24VDC. Mixed-voltage door hardware can be powered from the same enclosure.
Q: What is the PTC output current rating on the distribution outputs?
A: Both the power distribution module and the access power controller use 2.5A PTC-protected outputs. PTCs reset automatically after a fault clears — no fuse replacement required on a service call.
Q: Is the T1VK34D compatible with HID controllers other than Aero and Vertx?
A: Based on available specifications, the T1VK34D enclosure is specifically designed and sized for HID Aero and Vertx intelligent controller modules — up to two modules per enclosure. Compatibility with other HID controller families is not confirmed in the product documentation.
The T1VK34D is a pre-wired access power assembly I recommend specifically when a project calls for HID Aero or Vertx controllers and the AHJ will be inspecting for a UL294-listed power source. The all-in-one 24VDC/6A supply with onboard 12VDC regulation and dual 7AH battery standby in a single listed enclosure removes the most common cause of failed inspections on HID-based installs — mismatched or unlisted battery cabinets wired externally.
Technical Highlights:
- 6A Continuous at 24VDC: This is a continuous rating, not a surge rating — two HID Aero modules plus door hardware rarely exceeds 4A total draw, so there is meaningful headroom before any thermal limiting occurs under normal operating conditions.
- Dual-Voltage Distribution (12VDC and/or 24VDC): The onboard regulator delivers up to 6A at 12VDC simultaneously with 24VDC distribution outputs, each PTC-protected at 2.5A — this is the spec that makes mixed-voltage retrofits practical without adding a second enclosure.
- UL294 and cUL s319-05 Dual Listing: Both US and Canadian listings on the same assembly; for projects spanning the border or for Canadian provincial inspections requiring s319-05, this eliminates the need to source a separate listed enclosure for each jurisdiction.
Deployment Considerations:
- Verify the 28VAC/VDC @ 2.5A relay rating against your specific door hardware — high-current mag-locks drawing above 1.5A steady-state approach the relay's thermal limits and may require a dedicated relay module rather than the integrated controller outputs.
- The 49°C upper operating limit is the spec most commonly missed in non-air-conditioned mechanical rooms in southern US climates during summer — measure ambient before commissioning, particularly if the enclosure is mounted near heat-generating equipment.
The T1VK34D fits best in mid-size commercial deployments — office buildings, schools, or healthcare facilities running a four-door HID Aero or Vertx footprint where a single listed, self-contained enclosure simplifies both the installation and the AHJ approval process.
