Altronix T3M77XK1Q 12VDC Networked Power Supply with LINQ and Battery Backup
Overview
The Altronix T3M77XK1Q is a commercial-grade, network-manageable power supply combining the T3M77XK1 multi-output power unit with LINQ remote management — designed for enterprise physical security installations where power oversight, battery backup, and remote diagnostics matter. At 95.6 lb. and occupying a 36.12" × 30.125" × 7.06" enclosure, this is a cabinet-scale unit built for centralized power distribution across large access control, surveillance, or integrated security infrastructure. If you're managing dozens of field devices and need per-output visibility without rolling a truck, the T3M77XK1Q is architected for exactly that scenario.
Key Features
- 12VDC / 6A Continuous Output: Delivers a steady 6 amps at 12VDC — sufficient to drive multiple access control panels, locks, or camera heads from a single regulated source without voltage sag under sustained load. Regulated output means downstream devices see consistent voltage even as AC input fluctuates.
- Auxiliary 1A Unswitched Output: The 1A auxiliary rail stays live regardless of switched output states — useful for powering always-on devices like network modules or status indicators that must not cycle when the main outputs are controlled or reset.
- 12VDC / 12AH Battery Backup Capacity: The 12AH battery rating provides meaningful hold-up time during AC outages. On a 6A continuous load, expect roughly 1–1.5 hours of standby operation — long enough to outlast most utility interruptions and allow controlled shutdown of supervised systems.
- LINQ Network Management Integration: The LINQ module brings 24VDC network input (fused at 15A/32V) and per-output monitoring back to a central management platform. Operations teams can check output status, receive fault alerts, and remotely cycle outputs without physical access to the cabinet — a significant operational advantage in multi-site deployments.
- Network Output Ratings — 3A / 32V: The network-side outputs are rated at 3A/32V, appropriate for powering LINQ-attached devices and network-side accessory loads. Size your network branch loads accordingly to stay within this envelope.
- 120VAC / 60Hz Input, 6.3A Fused: Standard North American single-phase AC input with a 6.3A/250V input fuse — compatible with any standard 15A or 20A commercial circuit. The fuse rating provides appropriate protection for the 6A output stage and keeps the unit within standard branch circuit limits.
- Wide Operating Temperature Range — 0°C to 49°C: Rated for environments up to 49°C (120°F) — covers most indoor mechanical rooms, IDF closets, and security head-end rooms even without dedicated cooling. Storage rating extends to 70°C, so the unit ships and warehouses safely in hot climates.
- 289 BTU/Hr. Thermal Output: At 289 BTU/Hr., this unit has a measurable impact on enclosure thermal load. Plan your head-end room cooling budget accordingly — in a rack with multiple power supplies, aggregate BTU load can push a standard server room to its HVAC limits.
- 85% Max Relative Humidity Rating: Non-condensing humidity tolerance to 85% covers most commercial and light-industrial environments without requiring a climate-controlled room — though condensation from rapid temperature swings is still a concern in unheated spaces.
Integration and Compatibility
The T3M77XK1Q integrates with the Altronix power and access control ecosystem through its LINQ network management bus. LINQ-enabled systems allow this unit to report output status and faults to a central head-end, making it a natural fit for large access control deployments where per-door power visibility reduces diagnostic time. The 12VDC output is compatible with the broad range of 12V-rated electromagnetic locks, door controllers, and IP camera systems commonly found in enterprise security infrastructure. For installers planning multi-zone power distribution, pair this unit with a PoE-capable network switch to cover IP camera runs while T3M77XK1Q handles the access control power bus. When sizing your installation, consult the security power supplies category for complementary Altronix distribution modules if your load exceeds 6A continuous.
Frequently Asked Questions
Q: What is the continuous output current rating of the T3M77XK1Q?
A: The T3M77XK1Q delivers 6A continuous at 12VDC. There is also an auxiliary unswitched output rated at 1A, which remains active regardless of switched output states.
Q: What battery capacity does the T3M77XK1Q support?
A: The unit supports a 12VDC / 12AH battery for backup power during AC outages, providing meaningful hold-up time on a sustained 6A load.
Q: What is the input voltage requirement for the T3M77XK1Q?
A: The T3M77XK1Q requires 120VAC, 60Hz input power, protected by a 6.3A/250V input fuse — compatible with standard North American commercial branch circuits.
Q: What are the LINQ network input specifications on the T3M77XK1Q?
A: The LINQ module accepts 24VDC network input, fused at 15A/32V. Network-side outputs are rated at 3A/32V.
Q: What is the operating temperature range for the T3M77XK1Q?
A: Operating temperature is 0°C to 49°C (32°F to 120°F). Storage temperature extends from -20°C to 70°C.
Q: How large and heavy is the T3M77XK1Q enclosure?
A: The enclosure measures 36.12" × 30.125" × 7.06" and weighs 95.6 lb. (product weight). Shipping weight is 108.8 lb. with shipping dimensions of 40.75" × 35.25" × 12". Plan for two-person handling and verify rack or wall clearances before installation.
The T3M77XK1Q is the unit I reach for when a customer needs networked power visibility at scale — the LINQ integration means you're not flying blind on output health across a large campus, and the 12AH battery capacity gives you real hold-up time rather than the token backup you see on smaller supplies. At 95.6 lb. and nearly 37 inches wide, this is not a one-person installation; budget for a two-person crew and verify your mounting surface can handle the load before scheduling the install.
Technical Highlights:
- 6A Continuous at 12VDC: Enough headroom to run multiple 12V locks, controllers, or camera heads simultaneously without drooping voltage — the 6.3A input fuse is appropriately sized to protect the output stage and stay within a standard 15A commercial branch circuit.
- 12AH Battery Backup: On a 6A sustained draw, 12AH gives you roughly 1–1.5 hours of hold-up — enough to outlast most utility blips and give supervised systems time for controlled shutdown procedures.
- 289 BTU/Hr. Heat Load: This is a meaningful thermal contribution. In a tight IDF closet with multiple power supplies, the aggregate BTU load can stress standard HVAC — factor this into your head-end room thermal budget at design time, not after equipment is racked.
Deployment Considerations:
- The LINQ network input draws 24VDC and is fused at 15A/32V — confirm your LINQ bus supply is correctly sized and that network branch loads don't exceed the 3A/32V per-output rating on the network side.
- The 85% relative humidity rating covers most commercial environments, but avoid installations near HVAC condensate sources or in unheated spaces where rapid temperature swings can push humidity past the rated ceiling transiently.
This unit is well-matched to multi-building enterprise campuses or large commercial facilities — hospitals, universities, corporate headquarters — where centralized power management across dozens of access control doors justifies the cabinet footprint and where LINQ-driven remote diagnostics reduce technician dispatch costs meaningfully over a multi-year service horizon.
