Altronix T3CVK7720D 20-Door Access Control Power Integration Kit
Overview
The Altronix T3CVK7720D is a fully integrated access control power distribution solution combining a TROVE3 enclosure, CDVI controller interface, power supply, and UL-listed power distribution into a single field-ready assembly. Designed for commercial and enterprise deployments requiring centralized power and control for up to 20 doors, the T3CVK7720D eliminates the coordination overhead of sourcing and mounting separate components — everything ships pre-assembled in a 36.12" x 30.125" x 7.06" enclosure ready for wall installation.
UL294 and CAN/ULC-S319-05 listings make this kit compliant for life-safety access control applications in the US and Canada, and CE marking covers European installations. If your project specs require listed equipment from panel to reader, this assembly covers it without requiring individual component certification cross-checks.
Key Features
- 24VDC / 10A Regulated Output: Delivers stable 24VDC at up to 10A — enough headroom to power CDVI controllers, locks, readers, and auxiliary devices simultaneously without voltage sag under load. Sized for multi-door enterprise panels, not single-entry retrofits.
- 20-Door Control Capacity: Pre-integrated CDVI interface supports up to 20 controlled doors from a single enclosure. For mid-size commercial buildings or campuses consolidating access onto fewer panels, this reduces the number of enclosures to manage and audit.
- 8-Output PTC Power Distribution: Eight individually PTC-protected outputs replace fuse blocks with self-resetting thermal protection — a blown output resets automatically after the fault clears, cutting truck rolls for nuisance trips and simplifying troubleshooting on distributed lock and reader circuits.
- 12AH / 12VDC Battery Backup: Onboard 12AH battery sustains the system through mains outages. Sized for code-compliant access control standby requirements in most jurisdictions — verify your AHJ's specific hold-time spec before finalizing the design.
- 115VAC / 60Hz Input, 4.2A Max: Standard North American single-phase input with a modest 4.2A draw. A single 15A circuit supports multiple units, simplifying electrical rough-in on new builds.
- UL294 / CAN/ULC-S319-05 / CE Listed: Carries all three agency marks from a single integrated assembly. Specifying listed components simplifies the inspector sign-off process and satisfies most enterprise procurement compliance requirements.
- 0°C to 49°C Operating Range: Rated for standard indoor mechanical room and IDF closet environments. Not rated for outdoor or unheated space — plan accordingly for northern climate installations where closet temps may drop below freezing.
- 263 BTU/Hr. Dissipation: At full load the enclosure dissipates 263 BTU/Hr. In tight IDF closets or shared telecom rooms, factor this into your HVAC load calculations — especially if stacking multiple units.
Integration & Compatibility
The T3CVK7720D is built around the CDVI controller platform and TROVE3 enclosure architecture. The pre-integrated assembly assumes a CDVI-based access system — verify controller firmware and reader compatibility with your CDVI deployment before ordering. The PTC-protected outputs accommodate electric strikes, magnetic locks, and card readers within the 28VAC/VDC at 2.5A relay rating per output. For access control systems requiring higher per-door current draw (electrified panic hardware, heavy-duty mag-locks above 2.5A), plan supplemental power at the door level. Review the full Altronix catalog for compatible expansion modules and ancillary power supplies that pair with TROVE enclosure systems.
Frequently Asked Questions
Q: What agency listings does the T3CVK7720D carry?
A: The T3CVK7720D is listed under UL294, CAN/ULC-S319-05, and CE — covering US, Canadian, and European access control installation requirements.
Q: How many doors can the T3CVK7720D support?
A: The integrated CDVI controller interface supports up to 20 doors from a single enclosure assembly.
Q: What is the battery backup capacity?
A: The unit includes a 12AH / 12VDC battery. Actual standby duration depends on total connected load — verify against your AHJ's required hold time.
Q: Can the T3CVK7720D be used in an unheated outdoor enclosure?
A: No. The operating temperature range is 0°C to 49°C, which is suitable for conditioned indoor spaces. Unheated outdoor or northern-climate installations may fall outside this range.
Q: What is the relay rating for the power distribution outputs?
A: Each of the 8 PTC-protected outputs is rated at 28VAC or VDC at 2.5A. Loads exceeding 2.5A per circuit require supplemental power at the door.
Q: What are the enclosure dimensions?
A: The enclosure measures 36.12" x 30.125" x 7.06". Shipping dimensions are 40.75" x 35.25" x 12" at 92 lb. — plan for a two-person lift and verify wall stud spacing before installation.
The T3CVK7720D is one of those assemblies that saves a real amount of labor on mid-size commercial projects — pre-integrated CDVI controller interface, UL294-listed power supply, and 8-output PTC distribution in a single 36-inch enclosure means less field wiring, fewer certification headaches, and a cleaner inspector walkthrough. The 20-door capacity in particular hits the sweet spot for multi-tenant office builds and mid-campus deployments where a single panel covers a full floor or building wing.
Technical Highlights:
- 24VDC / 10A Supply: The 10A output gives you real headroom on a 20-door system — average door with reader and mag-lock draws 500–800mA, so even a fully loaded panel still has margin for auxiliary devices without triggering voltage droop.
- 8-Output PTC Protection: Self-resetting thermal cutoffs on each output mean a shorted lock circuit doesn't take down adjacent doors or require a fuse replacement. On a 20-door panel, that's a meaningful reduction in maintenance call-outs.
- 263 BTU/Hr. Heat Load: At full draw this unit puts out 263 BTU/Hr. — roughly equivalent to a small space heater. In a shared IDF closet with other active equipment, that load adds up fast. Factor it into the room's cooling budget before signing off on the panel location.
Deployment Considerations:
- At 85 lb. installed (92 lb. shipping), this is a two-person wall mount minimum. Verify that the wall structure can handle the load — concrete block or steel stud with backing is the right call, not standard drywall.
- The 0°C lower operating limit is a real constraint in northern climates. Mechanical rooms near exterior walls or loading docks can drop below freezing in winter — if there's any doubt about the closet temperature, add a thermostatically controlled heater or relocate the panel.
The T3CVK7720D is the right specification for a new-construction commercial office or campus building where the electrical engineer has already designed a CDVI-based access system and the GC needs a single listed assembly to mount, wire, and hand off to the AHJ inspector — not a piecemeal integration project.
