Altronix T2M5PCK1 Pre-Wired 12VDC Surveillance Power Supply Kit
Overview
The Altronix T2M5PCK1 is a factory pre-wired power supply and battery standby kit built around the T2MK5FPS8 platform — a UL294- and cUL-listed solution designed for integrators who need a proven, code-compliant power source for access control panels, door hardware, and surveillance devices without spending hours on field wiring. Pre-wired from the factory means the internal harness is already assembled and tested before it ships, reducing commissioning time on tight installation schedules.
The kit delivers 12VDC at 10A continuous from a 120VAC/60Hz input, with a 3.5A input draw and a 5A/250V input fuse protecting the primary side. A separate 1A unswitched auxiliary output handles low-draw peripherals — status indicators, relays, or auxiliary sensors — without pulling from the main 10A rail. Output-side 3A/32V fuses protect downstream devices and wiring from overcurrent events. For access control deployments where a panel or lock array needs both conditioned power and local battery standby, this is a practical, pre-tested assembly rather than a parts-bin build.
Key Features
- 12VDC @ 10A Main Output: Enough headroom to simultaneously power multiple electric locks, a small access control panel, and ancillary readers — without margining a smaller 4A or 6A supply and risking brownout on lock release events.
- 12AH Sealed Battery Backup: At typical access control loads, a 12VDC/12AH battery provides several hours of standby — meeting the backup requirements many insurance carriers and facility managers specify for door security systems.
- 1A Unswitched Auxiliary Output: Keeps low-draw peripherals energized regardless of main output state — useful for supervisory circuits, status LEDs, or auxiliary relay coils that need to stay live during panel resets.
- 3A/32V Output Fusing: Per-output fuse protection limits fault propagation — a shorted lock or cable fault blows its own fuse rather than taking down the entire power bus, which matters when multiple doors share a single enclosure.
- UL294, cUL s319-05, CE Listed: Agency listings satisfy AHJ requirements on commercial projects where the power supply must be listed to UL294 (access control) or Canadian equivalent — no workarounds or variance requests needed.
- Factory Pre-Wired (T2MK5FPS8 Platform): Internal harness assembled and tested at the factory. Field installation is mount, connect input, connect outputs — no internal wiring labor, which reduces risk of wiring errors on multi-technician crews.
- 0°C to 49°C Operating Range: Covers typical indoor mechanical room and IDF closet environments. If your installation is in an unconditioned space that exceeds 49°C (120°F) in summer, plan for ventilation or a different enclosure.
- Large Enclosure (27.25" x 21.5" x 6.5"): The enclosure dimensions accommodate the battery and board with room for field wiring management — integrators running conduit and landing multiple circuits appreciate the physical space.
Integration and Compatibility
The T2M5PCK1 operates on standard North American 120VAC/60Hz — no step-down transformer needed in US installations. The 12VDC output is compatible with the majority of electric strikes, magnetic locks, and access control panels operating on 12V. Verify your panel's current draw against the 10A main rail before adding locks; a four-door panel with four mag-locks can approach 8–9A under simultaneous release load. The power supply integrates into any installation where access control hardware or perimeter surveillance devices require a UL294-listed local power source with battery backup. Review the Altronix product line for companion distribution modules if you need to expand output circuits beyond the on-board configuration. Consult the security power supply buying guide for load calculation methodology before finalizing your design.
Frequently Asked Questions
Q: What is the battery backup capacity of the T2M5PCK1?
A: The T2M5PCK1 includes a 12VDC/12AH sealed battery, providing several hours of standby at typical access control loads depending on the connected device draw.
Q: Is the T2M5PCK1 UL listed?
A: Yes. The T2M5PCK1 carries UL294, cUL s319-05, and CE agency listings, satisfying AHJ requirements on commercial access control installations in the US and Canada.
Q: What is the main output voltage and current of the T2M5PCK1?
A: The main output is 12VDC at 10A continuous. There is also a separate 1A unswitched auxiliary output for low-draw peripherals.
Q: What input power does the T2M5PCK1 require?
A: It requires 120VAC at 60Hz with a maximum input current draw of 3.5A. A 5A/250V fuse protects the primary input side.
Q: What are the enclosure dimensions of the T2M5PCK1?
A: The enclosure measures 27.25 inches wide by 21.5 inches tall by 6.5 inches deep, providing ample room for the battery, board, and field wiring.
Q: What is the operating temperature range of the T2M5PCK1?
A: The rated operating range is 0°C to 49°C (32°F to 120°F), suitable for conditioned indoor mechanical rooms and IDF closets.
The T2M5PCK1 is the unit I reach for when a project spec calls for UL294-listed power with battery backup and the installation crew can't afford to spend half a day wiring an enclosure from scratch. The factory pre-wired T2MK5FPS8 platform ships tested — that distinction matters on multi-door commercial projects where field wiring errors under a deadline create callbacks.
Technical Highlights:
- 10A Main Rail with 3A/32V Output Fusing: Enough current for a four-door panel plus peripherals, and per-output fusing means a shorted cable takes out one circuit, not the whole board — a real operational advantage over unfused distribution.
- 12AH Battery: At a realistic 2–3A load (small panel plus two mag-locks on standby), a 12AH cell delivers 4–6 hours of backup — meeting the minimum standby window most commercial security specs require without an external battery module.
- 91 BTU/Hr Heat Output: Plan your enclosure ventilation accordingly. In a sealed mechanical room already running warm, 91 BTU/Hr from this unit alone can push temperatures toward the 49°C operating ceiling — don't skip the thermal calculation.
Deployment Considerations:
- Verify your combined lock and panel draw against the 10A main rail before commissioning — four high-current mag-locks (each ~500mA hold, up to 1A release) plus a panel can approach the ceiling under simultaneous door release scenarios.
- The 49°C upper operating limit is the spec to watch in unconditioned spaces. Summer ambient in a rooftop IDF or exterior-adjacent closet can exceed this — add a louvered vent panel or specify a ventilated enclosure option if ambient is a concern.
The T2M5PCK1 is a strong fit for mid-size commercial tenant buildouts — four to eight doors, conditioned IT or mechanical room, AHJ requiring UL294 listing — where pre-wired factory assembly reduces installation variance and the 12AH battery satisfies standard backup duration requirements without an external battery cabinet.
