Altronix T3DCR77LXK1 16-Output 24VDC Power Distribution Cabinet
Overview
The Altronix T3DCR77LXK1 is a large-format, rack-capable power distribution cabinet designed for high-density surveillance and access control installations where centralizing DC power in a single, protected enclosure is the priority. Rated at 10A continuous at 24VDC from a 115VAC/60Hz input, this unit is built around a 16-output fused and alarmed distribution model — meaning individual output faults do not cascade across the full system. For integrators running 12 to 16 camera or access control devices from a single panel location, the T3DCR77LXK1 eliminates the parallel-run of individual wall-plug adapters and consolidates power supervision into one CE-listed assembly.
The cabinet ships with a 12VDC/12AH sealed lead-acid battery position, providing integrated standby capability when paired with the appropriate charger circuit. Operating range spans 0°C to 49°C — workable in most IDF closets, electrical rooms, and mechanical spaces, though not rated for outdoor or uncontrolled-temperature environments. At 85.6 lb and 36.12" x 30.125" x 7.06", this is a substantial steel enclosure that requires pre-planned wall anchoring or rack positioning before any wiring begins.
For projects specifying Altronix power distribution equipment, the T3DCR77LXK1 sits in the upper tier of their multi-output DC cabinet line — appropriate for enterprise lobby builds, perimeter surveillance rings, or large-scale IP camera deployments where device count per zone justifies a dedicated power enclosure rather than distributed PoE.
Key Features
- 10A Continuous at 24VDC: A sustained 10A output ceiling means you can load 16 outputs to roughly 0.625A average per channel without triggering thermal derating — practical headroom for mixed camera and reader loads where not every device draws peak simultaneously.
- 16 Fused/Alarmed Outputs: Per-output fuse protection means a shorted cable or failed device blows its individual fuse rather than pulling down the bus. Alarm contacts on each output give your head-end or monitoring panel visibility into individual circuit faults — a meaningful operational advantage over unfused distribution blocks in large installs.
- 115VAC / 60Hz Input at 8.4A Max: Draws under a single 15A branch circuit breaker, which simplifies electrical rough-in. Confirm your panel has a dedicated 20A circuit available; sharing with other loads is not recommended given the 8.4A draw ceiling.
- Integrated 12VDC/12AH Battery Position: On-board battery support keeps outputs live during brief outages without requiring a separate UPS rack unit. 12AH capacity at 24VDC output delivers meaningful hold time for low-draw surveillance loads — actual runtime depends on total connected current draw, so size your battery for the worst-case overnight outage window your customer requires.
- CE European Conformity Listed: CE listing confirms the unit has been evaluated against relevant European safety and EMC directives — useful for multi-site accounts with EU locations or for integrators whose procurement requires a recognized conformity mark.
- Steel Enclosure, 85.6 lb: The robust steel cabinet protects internal wiring from physical interference and provides a tamper-deterrent enclosure for the power bus. The 85.6 lb weight means two-person mounting is mandatory — factor this into your installation crew schedule.
- Operating Temperature 0°C to 49°C: Covers conditioned mechanical rooms and most IDF closets. Not suitable for attic spaces, unconditioned warehouses, or outdoor installations where ambient can exceed 49°C in summer — plan HVAC or select a different enclosure class for those environments.
- Storage Temperature to 70°C: Wider storage range (-20°C to 70°C) allows warehouse or van stocking in temperature-variable climates without risking component damage before installation.
Integration & Compatibility
The T3DCR77LXK1 is a power supply and distribution device, not a network device — it has no IP address, no SNMP interface, and no VMS integration layer. Integration into a broader security system means wiring the alarm output contacts to your access control panel or alarm input module so that output faults surface in your monitoring software. Consult your panel's input wiring spec for dry-contact compatibility before running alarm circuits.
24VDC output is compatible with the majority of 24V-rated PTZ cameras, access control readers, and door hardware. Verify each device's exact voltage tolerance — some access hardware is 24VAC-rated only, which is a different supply class. For PoE-based IP cameras, this unit does not provide PoE; pair it with a dedicated PoE switch for those devices, and reserve the T3DCR77LXK1 outputs for non-PoE 24VDC loads.
If your design mixes PoE cameras with 24VDC access control hardware in the same closet, a network video recorder pairing strategy — NVR handling PoE, T3DCR77LXK1 handling access control power — keeps power budgets and fault domains cleanly separated.
Frequently Asked Questions
Q: What is the continuous output current of the T3DCR77LXK1?
A: The T3DCR77LXK1 delivers 10A continuous at 24VDC across its 16 outputs. Individual channel current is determined by the installed fuse rating per output.
Q: Does the T3DCR77LXK1 include a battery, or just the battery position?
A: The unit is specified with a 12VDC/12AH battery capacity — verify with your distributor whether the battery ships included or must be ordered separately, as configurations vary.
Q: Can the T3DCR77LXK1 power PoE IP cameras directly?
A: No. This unit outputs 24VDC and does not provide PoE (802.3af/at/bt). It is intended for 24VDC-rated devices such as PTZ cameras with 24VDC input, access control readers, and door hardware. PoE cameras require a separate PoE-capable switch or injector.
Q: What agency certifications does the T3DCR77LXK1 carry?
A: The T3DCR77LXK1 carries CE European Conformity listing. No additional UL or ULC listing is noted in available evidence — confirm with your AHJ if a specific listing is required for your jurisdiction.
Q: Is the T3DCR77LXK1 suitable for outdoor installation?
A: No. The operating temperature range is 0°C to 49°C and the enclosure is not rated for outdoor exposure. Install in a conditioned mechanical room, IDF closet, or similar controlled environment.
Q: How much wall space and load capacity is required to mount the T3DCR77LXK1?
A: The enclosure measures 36.12" x 30.125" x 7.06" and weighs 85.6 lb. Two-person installation is required. Ensure wall anchors or rack mounting hardware is rated for at least 100 lb to accommodate the unit plus battery and cabling weight.
The T3DCR77LXK1 is the kind of unit I specify when a job has 12 or more 24VDC devices in a single closet and the customer needs fault visibility per output — not just a shared bus that goes dark when one device shorts. The 10A continuous ceiling at 24VDC, combined with 16 individually fused and alarmed outputs, gives you a real operational picture rather than a guessing game when a field device fails at 2am.
Technical Highlights:
- 10A @ 24VDC Continuous: Sustained output — not a peak rating — means you can plan your load budget to 10A total without worrying about thermal throttling under normal operating conditions. At 16 outputs, that's roughly 0.6A average per channel for fully loaded configurations.
- 8.4A Max Input Draw: Fits cleanly on a single 15A dedicated branch circuit with margin. If your electrical room has only 20A circuits available, this unit won't force a panel upgrade — a practical consideration on retrofit jobs.
- 12VDC/12AH Battery Integration: Built-in battery position avoids the cost and space of a separate UPS. 12AH at 24VDC output provides real hold time for low-draw surveillance loads — though you'll want to calculate runtime against your actual connected current for any job with a documented outage-window requirement.
Deployment Considerations:
- At 85.6 lb and 36.12" x 30.125", this is not a solo-install enclosure. Budget two technicians and confirm wall anchor points or rack rail capacity before the unit arrives on site — the weight class makes field repositioning painful.
- Operating ceiling is 49°C — adequate for most conditioned spaces, but attic runs, unconditioned warehouses, or mechanical rooms with seasonal HVAC failures will push that limit. If ambient can spike above 49°C, select a different enclosure or add supplemental cooling.
This unit belongs in enterprise lobby or perimeter ring deployments where 24VDC access control hardware and non-PoE cameras share a common power closet and the operations team needs per-circuit fault reporting surfaced to their monitoring platform — not in small retail or residential retrofit jobs where a single-output supply is all the load warrants.
