Altronix T3MB55PK1D 16-Door Pre-Wired Access Control Power Distribution Kit
Overview
The Altronix T3MB55PK1D is a factory pre-wired access control power distribution kit built around the T3MB55F16PD enclosure — designed for integrators who need to commission a 16-door system without hand-wiring every power and reader interface connection on site. The assembly combines a 120VAC/60Hz input power supply delivering 12VDC at 10A with 11 reader interface modules and a single controller slot, all pre-terminated inside a steel enclosure measuring 36.12" x 30.125" x 7.06". If your crew spends billable hours in the mechanical room punching down terminals, this kit is built to recover that time.
Key Features
- 12VDC / 10A Output: A full 10 amps at 12 volts feeds up to 16 doors of readers, locks, and control hardware — enough headroom for magnetic locks and electric strikes without a supplemental supply on most mid-size deployments.
- 40AH / 65AH Battery Charging: Onboard charging supports batteries up to 65AH, giving you extended standby capacity — critical for facilities where code requires 4+ hours of backup power for access control during a power outage.
- 16-Door Capacity with 11 Reader Interface Modules: The T3MB55PK1D ships with 11 reader interface modules pre-installed, supporting Wiegand or Clock-and-Data readers across a full 16-door system with a single controller — less field assembly, fewer wiring errors.
- Factory Pre-Wired Assembly: Internal wiring is completed at the factory, not the job site. This eliminates a common source of commissioning callbacks and reduces the installation window for large door counts.
- Large Steel Enclosure (36" x 30" x 7"): The cabinet provides enough interior depth and width to house the controller, battery, and distribution hardware together — a single lockable location for the entire access power infrastructure.
- CE Listed: European Conformity listing supports deployments in CE-compliant environments and signals baseline electrical safety standards.
- Operating Range 0°C to 49°C: Rated for mechanical rooms, IDF closets, and indoor utility spaces where temperatures can climb — but not for unheated outdoor enclosures or below-freezing environments.
Integration & Compatibility
The T3MB55PK1D is designed to pair with Altronix's access control ecosystem, including compatible controllers from major access platforms. The 16-door, single-controller architecture fits mid-size commercial buildings, campus buildings, or floor-by-floor deployments where one controller governs an entire zone. Verify controller compatibility with your access platform before specifying — the reader interface module count (11) determines how many reader positions are pre-wired without field additions. For access control systems requiring higher door counts, evaluate multi-controller Altronix configurations. Pair with appropriately rated 12V sealed lead-acid batteries (up to 65AH) for code-compliant standby capacity. See the Altronix product line for compatible power supplies and expansion modules. Integrators specifying access control power supplies at scale should also review Altronix's single-door and multi-door power distribution options for right-sizing. If you're evaluating total system architecture, a centralized recording and management approach may inform how door counts map to controller zones.
Frequently Asked Questions
Q: What is the output voltage and current of the T3MB55PK1D?
A: The T3MB55PK1D delivers 12VDC at 10A output, powered from a 120VAC/60Hz input.
Q: How many doors does this kit support?
A: It supports up to 16 doors using a single controller and 11 pre-installed reader interface modules.
Q: What size batteries can the T3MB55PK1D charge?
A: The onboard charger supports sealed lead-acid batteries up to 40AH or 65AH depending on configuration — useful for meeting backup power requirements.
Q: Is the T3MB55PK1D pre-wired from the factory?
A: Yes. The T3MB55F16PD enclosure assembly ships with internal wiring completed at the factory, reducing field labor and wiring errors during installation.
Q: What are the enclosure dimensions?
A: The enclosure measures 36.12" x 30.125" x 7.06" and ships in a box measuring 40.75" x 35.25" x 12". Product weight is 85.6 lb.
Q: What agency listings does the T3MB55PK1D carry?
A: It carries CE European Conformity listing. Verify additional regional certifications with Altronix if your project requires UL or other local listings.
The T3MB55PK1D is one of the more practical specifications I see on mid-size commercial access jobs — 16 doors, one controller slot, and 11 reader interface modules pre-terminated before it ever leaves the factory. On a typical 8-hour install window, that pre-wired assembly recovers two to three hours that would otherwise go to point-to-point terminations inside the cabinet.
Technical Highlights:
- 10A at 12VDC: Sufficient headroom for 16 doors running electric strikes or mag-locks without a supplemental power supply on standard commercial hardware — keeps your panel count down.
- 65AH Battery Support: The charger's 65AH ceiling lets you spec a full-size standby battery for 4-hour backup compliance without adding an external charger or a second enclosure.
- 36" x 30" x 7" Cabinet: Enough interior volume to house the controller, battery, and all distribution hardware in one lockable location — one cabinet to inspect, one cabinet to service.
Deployment Considerations:
- The operating temperature ceiling is 49°C — adequate for most mechanical rooms, but confirm ambient temps in tight IDF closets with high-density switching gear before mounting.
- Eleven reader interface modules are pre-installed; if your door count pushes the full 16 with dual readers per door, verify your controller's reader port capacity independently before finalizing the spec.
This kit is best suited for a single-floor or single-zone 16-door buildout in a commercial office, healthcare corridor, or education building where the goal is a clean, auditable power infrastructure that a technician can service without tracing field-run wiring.
