Altronix T2MK3F8PD Power Supply Distribution Enclosure Kit
Overview
The Altronix T2MK3F8PD is a pre-packaged power distribution kit built around the TROVE2 enclosure, the M2 power supply module, and an 8-output distribution board — a purpose-built solution for integrators who need to consolidate 12VDC or 24VDC surveillance device power without building their assembly from individual components. If you're wiring multi-camera runs, access control locks, or mixed device loads that need individually fused outputs and a clean, code-ready enclosure, the T2MK3F8PD is designed to drop into that workflow.
It carries UL294, cUL, and CE agency listings — which matters on commercial projects where the AHJ will ask for documentation at final inspection. The enclosure dimensions (27.25" × 21.5" × 6.5") give you enough interior real estate to route conduit and cable neatly without the cramped conditions that create maintenance headaches later. The Altronix power solutions lineup treats this as a systems-level product, not just a box with a transformer inside.
Key Features
- Selectable 12VDC or 24VDC Output: Many surveillance installations mix device voltages — PTZ cameras at 24VDC, analog IR cameras at 12VDC, door strikes that can swing either way. The ability to configure this unit at one voltage for an entire distribution board means you pick the rail that matches your device population, rather than stacking separate supplies. Choose once at commissioning; the output is fixed per configuration.
- 6A Continuous Output: At 12VDC, 6 amps supports roughly 72 watts of continuous load — enough headroom to power 6–8 small fixed cameras, or fewer higher-draw devices with IR illuminators. Size your load budget at 80% of rated output (4.8A effective) to avoid nuisance fuse trips under thermal derating.
- 8-Output Fused Distribution (3A/32V per Output): Each of the 8 outputs is individually protected at 3A/32V. A fault or short on one camera run opens that fuse without dropping the remaining 7 devices — critical in multi-door or multi-camera installs where a wiring fault on one run shouldn't take down an entire wing. Troubleshooting is also faster: you find the blown fuse rather than chasing a systemic fault.
- Integrated Battery Charging (12VDC / 12AH): The onboard charger supports a 12AH standby battery, making this a complete power-with-backup solution in a single enclosure. For access control applications where life-safety doors must remain powered during an outage, this eliminates a separate UPS or battery module — and keeps the installation footprint compact. Battery is not included; you source a 12VDC/12AH sealed lead-acid to fit.
- 120VAC / 60Hz Input: Standard North American line input — connects directly to a dedicated breaker circuit. No step-down transformer, no voltage conversion required for US or Canadian installs.
- UL294, cUL, CE Listed: UL294 is the access control power supply standard; listing to it signals the unit has been evaluated for the specific demands of security system power — not just generic electronics safety. cUL extends that to Canadian jurisdictions. CE covers EU marking requirements if this equipment ships across projects.
- Operating Range 0°C to 49°C: Covers conditioned indoor environments typical of server rooms, IDF closets, and interior utility spaces. This is not rated for unconditioned attic or outdoor enclosure use — keep it in a temperature-controlled space.
Integration and Compatibility
The T2MK3F8PD fits naturally into surveillance power distribution infrastructure alongside IP cameras, analog HD cameras, and low-voltage access control hardware. The 8-output fused board supports up to 8 individually home-run device feeds — suitable for zone-based wiring schemes common in commercial access control and IP camera deployments. When designing your PoE switch and power architecture together, this unit handles the non-PoE 12/24VDC device population (analog cameras, door strikes, REX devices, sirens) while PoE switches handle the IP device layer separately. For a full system design approach, consult an access control power planning resource to match battery backup runtime to your door count and lock current draw.
The enclosure's 27.25" × 21.5" × 6.5" footprint is designed for wall-mount installation in equipment rooms or utility closets. Shipping weight runs 43.35 lbs — plan for two-person installation when mounting at height.
Frequently Asked Questions
Q: Can the T2MK3F8PD output both 12VDC and 24VDC simultaneously?
A: No. The output voltage is selectable — either 12VDC or 24VDC — but not both at the same time. All 8 distribution outputs operate at the same configured voltage.
Q: Does the T2MK3F8PD include a battery?
A: No battery is included. The unit supports a 12VDC / 12AH sealed lead-acid standby battery (sourced separately) for backup operation during AC power loss.
Q: What agency listings does the T2MK3F8PD carry?
A: The T2MK3F8PD is listed to UL294 (access control power supply standard), cUL (Canadian equivalent), and CE (European conformity marking).
Q: How many devices can I power from this unit?
A: The unit has 8 individually fused outputs, each rated 3A/32V. Total continuous output is 6A at 12VDC or 24VDC. As a practical guide, size your total connected device load to no more than 80% of rated output (approximately 4.8A) to maintain thermal headroom.
Q: Is the T2MK3F8PD suitable for outdoor installation?
A: No. The operating temperature range (0°C to 49°C) and the standard enclosure design indicate this unit is intended for conditioned indoor environments such as equipment rooms, IDF closets, and secured utility spaces.
Q: What are the enclosure dimensions for the T2MK3F8PD?
A: The enclosure measures 27.25" wide × 21.5" tall × 6.5" deep. Shipping dimensions are 32.5" × 26.5" × 11.125" and the unit ships at 43.35 lbs.
The T2MK3F8PD is a kit I recommend when an integrator is building out a 10–20 device site and wants consolidated, inspectable power without spec'ing a custom panel from scratch. The 6A continuous output at selectable 12/24VDC, combined with 8 individually fused outputs at 3A/32V each, gives you a clean distribution architecture — one failure point per run, not per zone.
Technical Highlights:
- 8 Individually Fused Outputs (3A/32V): A dead short on camera run 4 opens that fuse and leaves runs 1–3 and 5–8 fully operational. That's the difference between losing one camera and losing a wing during an incident.
- Integrated Battery Charging (12VDC/12AH): The onboard charger supports a 12AH standby battery — add a standard SLA and this becomes a self-contained power-with-backup enclosure, eliminating a separate battery module in the closet.
- UL294 Listing: This listing is specifically for access control power equipment, not just general electrical safety. For any project with life-safety doors, an AHJ can and will ask for this documentation at final inspection — having it pre-listed in the equipment schedule avoids a rework conversation.
Deployment Considerations:
- The 49°C upper operating limit means this unit belongs in a conditioned IDF or equipment room — not a non-air-conditioned utility closet or rooftop enclosure where summer ambient can push past that threshold.
- The enclosure ships at 43.35 lbs and the installed unit is 39.6 lbs at 27.25" × 21.5" — plan for two-person mounting and confirm your wall structure before installation day.
This kit earns its place on multi-door commercial access control projects or hybrid analog/IP camera installs in office buildings and schools — anywhere you need a code-ready, inspectable power distribution point that a service tech can troubleshoot fuse-by-fuse three years after commissioning.
