Altronix T3M77XK1DQ Dual-Output 12/24VDC Power Supply with LINQ Network Supervision
Overview
The Altronix T3M77XK1DQ is a dual-output power supply bundled with Altronix's LINQ network supervision module — a pairing aimed at integrators who need both reliable low-voltage DC power delivery and remote visibility into power status on the same installation. At its core, the T3M77XK1DQ supplies 12VDC or 24VDC across two independently managed outputs, drawing from a standard 115VAC wall feed. The LINQ module inclusion means this isn't just a power supply you install and forget — it's one you can monitor, which matters when that supply is feeding cameras, door controllers, or alarm devices in locations you're not checking on daily.

Key Features
- Selectable 12VDC or 24VDC Output: A single unit covers the two most common low-voltage device voltages in physical security — 12V for most IP cameras, sensors, and readers; 24V for many access control panels and electric strikes. That flexibility means fewer SKUs to stock when your installation mix is varied.
- Two Independent Outputs at 1.75A Each: Each output is rated at 1.75A, giving you 21W per channel at 12VDC or 42W per channel at 24VDC. For reference, a typical PoE-equivalent IP camera draws under 13W — so each output can comfortably drive one camera with headroom, or power lower-draw devices like readers and motion detectors without stressing the supply.
- 115VAC Input — No Transformer Adapter Required: Direct connection to standard North American building power. No step-down transformer, no adapter — the supply converts 115VAC mains directly to regulated DC output. This simplifies rough-in wiring and keeps the electrical BOM clean on smaller jobs.
- Bundled LINQ Network Supervision Module: LINQ is Altronix's IP-based supervision platform. Pairing it with a power supply at this tier means you get remote power status monitoring baked in from day one, rather than retrofitting it later. For managed installations or service-contract accounts, that real-time visibility into output status reduces truck rolls for intermittent power complaints.
- Dual Output Architecture for Zone Segmentation: Two outputs let you segment power by zone, device type, or criticality without deploying a second supply. Running cameras on one output and access control readers on another, for instance, means an overload or fault on one circuit doesn't take down both device classes — useful in regulated or life-safety adjacent deployments.
- Compact Power Supply Form Factor for Panel Integration: Altronix power supplies in this class are built for integration inside larger panel enclosures or equipment racks alongside access controllers, NVRs, or alarm panels. The T3M77XK1DQ fits within the power supply and distribution infrastructure of a standard security panel installation without requiring a dedicated enclosure footprint.
Integration and Compatibility
The T3M77XK1DQ is designed for deployment within broader Altronix-based power distribution systems. The LINQ module communicates over IP, so integration into an existing network for supervision requires a local network port at or near the panel location — plan for that during rough-in if your panel rooms don't already have data drops. Output voltage selection (12 or 24VDC) should be confirmed against the load devices before installation; mixing voltage-sensitive devices on a single output without confirmed ratings is the most common field error on multi-output supplies. This unit draws from 115VAC, placing it firmly in North American infrastructure — not suitable for 220/240VAC international installations. For larger deployments requiring more outputs or higher per-channel current, review higher-capacity models in the Altronix catalog such as the multi-output PD-series boards with separate charger stages. If you're sizing a complete surveillance power plan, the PoE and low-voltage power planning guide can help you match supply capacity to device load across a full camera and access control installation.
Frequently Asked Questions
Q: What output voltages does the T3M77XK1DQ support?
A: The T3M77XK1DQ supports 12VDC and 24VDC output. Both outputs operate at up to 1.75A per channel, allowing you to power 12V or 24V security devices depending on your installation requirement.
Q: What is LINQ and why does it matter for this power supply?
A: LINQ is Altronix's network-based power supervision platform. Bundling it with the T3M77XK1DQ gives you remote monitoring of power output status over IP — useful for managed service installations where you need visibility into power health without being on-site.
Q: How many devices can the T3M77XK1DQ power?
A: The unit has two outputs at 1.75A each. At 12VDC, each output delivers up to 21W — enough to power a typical IP camera or access control reader with headroom. Total device count depends on individual load draw per connected device.
Q: Is the T3M77XK1DQ compatible with 220VAC or international power?
A: No. The T3M77XK1DQ is rated for 115VAC input only, making it suitable for standard North American electrical installations. It is not compatible with 220/240VAC mains without an external step-down transformer.
Q: Can the T3M77XK1DQ be installed inside a security panel enclosure?
A: Altronix power supplies in this series are designed for integration within panel enclosures alongside access controllers and alarm equipment. Confirm enclosure dimensions against the unit's physical footprint before installation.
The T3M77XK1DQ sits in a specific niche of the Altronix lineup — it's not a high-current multi-output distribution board, and it's not a bare board supply. What it is: a two-output 12/24VDC supply at 1.75A per channel, bundled with LINQ network supervision right out of the box. That combination targets integrators running managed service accounts where remote power visibility is baked into the SLA rather than added as an afterthought.
Technical Highlights:
- 1.75A Per Output at 12/24VDC: At 12VDC that's 21W per channel — adequate for a single IP camera or access reader per output, with margin. At 24VDC it steps to 42W per channel, opening the door to electric strikes or larger panel loads. Know your load before selecting the voltage tap.
- Dual Independent Outputs: Two outputs mean you can segment by device class or zone without deploying a second supply. A fault or overload condition on one output doesn't cascade to the other — that's worth something in installations where mixed device types share a panel.
- LINQ Supervision Included: Bundling the LINQ module means the network management infrastructure is licensed and physically present from day one. Retrofitting LINQ to an existing supply after installation is a labor cost that this unit eliminates at the procurement stage.
Deployment Considerations:
- LINQ requires an IP network connection at the panel location. If your panel rooms don't have data drops, rough in a network port during installation — adding one after the fact is the most common avoidable cost on LINQ deployments.
- The 115VAC input is a hard constraint. International sites or facilities with 208/240VAC panel feeds are not compatible without an additional step-down transformer — budget for that if this unit is specified on a non-standard power infrastructure project.
This unit is well-suited for small commercial installations — a retail branch, a single-floor office, a multi-door access control retrofit — where two output zones are sufficient, remote monitoring is contractually required, and the convenience of a bundled supervision module justifies the kit pricing over buying the supply and LINQ board separately.
