Altronix T1AXK1F4PQ 24VDC Power Supply with Battery Backup, LINQ, and Fused Distribution
Overview
The Altronix T1AXK1F4PQ is a 24VDC/4A continuous-output power supply with integrated battery backup, LINQ remote management capability, and a fused multi-output power distribution board — built for commercial security installations where power continuity and centralized monitoring actually matter. It ships in an 18" x 14.5" x 4.62" steel enclosure that houses both the supply circuitry and a 7AH/12VDC standby battery, so your cameras, access control hardware, or door strikes stay powered through a utility outage without a separate UPS cabinet eating rack space. If you're specifying Altronix power solutions for a multi-device security deployment, the T1AXK1F4PQ covers the mid-scale sweet spot: enough current for four to six devices, enough battery reserve to bridge short outages, and LINQ telemetry so you know exactly what's happening at the panel without rolling a truck.
Key Features
- 24VDC at 4A Continuous Output: Four amps continuous is enough to drive multiple 24VAC/DC access control panels, electric strikes, or camera power injectors simultaneously — without the voltage sag that trips low-voltage protection on sensitive electronics. The 24VDC regulated rail stays stable even as load fluctuates across connected devices.
- Integrated 7AH/12VDC Battery Backup: The onboard 7 amp-hour sealed lead-acid battery slot keeps loads running during a utility interruption. At a 2A draw across connected devices, expect roughly 3+ hours of runtime — enough to cover most power-grid brownouts or brief outages without manual intervention. No external UPS required.
- LINQ Remote Management: LINQ connectivity lets building managers or security integrators monitor power status, battery health, and fault conditions from a central software console. In large deployments with dozens of panels across a campus, this is the difference between knowing about a failed supply in real time versus discovering it during an incident response.
- Dual-Voltage Distribution — 24VDC and 12VDC: An onboard voltage regulator steps the 24VDC rail down to 12VDC at up to 6A continuous, giving you both voltage rails from a single enclosure. Mixed installations running 24VDC door hardware alongside 12VDC cameras or sensors don't need a separate converter module.
- Fused Input and Output Distribution: The distribution board uses 15A/32V input fuses and individual 3A/32V output fuses per circuit. A short or overload on one device blows only that circuit's fuse — the rest of your load keeps running. This is the behavior you need in a life-safety or access control environment where losing all outputs simultaneously isn't acceptable.
- 120VAC/60Hz Input with 5A Input Fuse: Standard North American mains input makes installation straightforward — no special transformer or step-down required in typical US commercial buildings. The 5A/250V input fuse provides upstream protection for the supply itself.
- Commercial Operating Range (0°C to 49°C): Rated for ambient temperatures up to 49°C, which covers most IT closets, electrical rooms, and above-ceiling spaces without requiring supplemental cooling. Storage down to -20°C means it survives unheated warehouse or construction staging environments between installation phases.
- CE European Conformity Listed: CE listing confirms the unit meets applicable EU electromagnetic compatibility and low-voltage directives — relevant for projects with international compliance requirements or for integrators working on multi-region rollouts where equipment documentation is audited.
- 18" Steel Enclosure — Wall or Rack Mountable: The 18" x 14.5" x 4.62" enclosure is sized for standard wall mounting in an IDF closet or security room. The compact depth (under 5") keeps it from intruding into tight spaces, and the steel construction provides tamper resistance appropriate for an unattended utility space.
Integration and Compatibility
The T1AXK1F4PQ fits naturally into security power supply infrastructure alongside access control systems, IP camera installations, and intrusion detection panels. The dual-voltage output (24VDC main rail + 12VDC regulated output via onboard regulator) accommodates the mixed voltage environments common in retrofit projects where legacy 12VDC hardware coexists with newer 24VDC access control panels. LINQ compatibility integrates with Altronix's broader network monitoring ecosystem — if you're already running LINQ across a building, adding the T1AXK1F4PQ expands visibility without adding a separate monitoring platform. For integrators managing access control deployments across multiple floors or buildings, the per-circuit output fusing means a wiring fault on one door controller doesn't cascade into a building-wide power event. Pair this supply with a managed PoE switch on the network side to complete a fully monitored physical security power stack. For sizing guidance on multi-device deployments, refer to the security power planning guide to confirm load calculations before specifying output count and battery reserve.
Frequently Asked Questions
Q: What is the continuous output current of the T1AXK1F4PQ?
A: The T1AXK1F4PQ delivers 24VDC at 4A continuous from its main output rail. An onboard voltage regulator also provides a stepped-down 12VDC output at up to 6A continuous, giving you both voltage levels from a single enclosure.
Q: How long will the battery backup sustain connected devices during a power outage?
A: The unit includes a 7AH/12VDC sealed battery. Actual runtime depends on total connected load — at roughly 2A of aggregate draw, expect approximately 3+ hours of backup. Higher loads reduce runtime proportionally. Altronix recommends confirming battery sizing against your specific load profile during design.
Q: What does LINQ provide that standard power supplies don't?
A: LINQ is Altronix's remote monitoring interface. It allows security integrators and facility managers to check power status, battery condition, and fault events from a central software platform — without physically inspecting the panel. In multi-site or large campus deployments this is operationally significant for maintenance scheduling and incident response.
Q: Can the T1AXK1F4PQ power both 24VDC and 12VDC devices simultaneously?
A: Yes. The unit's onboard voltage regulator converts the 24VDC main rail to 12VDC at up to 6A continuous, so you can run 24VDC door controllers and 12VDC cameras or sensors from the same enclosure without an external converter.
Q: What fusing does the distribution board use?
A: The power distribution board uses 15A/32V input fuses and individual 3A/32V output fuses per circuit. Per-circuit fusing means a fault or short on one output blows only that fuse, leaving all other connected devices powered — a critical behavior in access control and life-safety applications.
Q: What are the enclosure dimensions and what is the operating temperature range?
A: The enclosure measures 18" x 14.5" x 4.62" (W x H x D). The unit is rated for operation from 0°C to 49°C (32°F to 120°F), covering most commercial electrical room and IDF closet environments without supplemental cooling.
The T1AXK1F4PQ is one of those supplies that earns its keep on mid-scale access control jobs where you need dual-voltage outputs and battery backup in a single lockable enclosure — not two separate boxes bolted side by side. The 6A continuous 12VDC regulated output on top of the 24VDC/4A main rail is what sets it apart for retrofit work: you can power legacy 12VDC lock hardware and newer 24VDC controllers from one panel, which simplifies both the wire run and the monitoring footprint via LINQ.
Technical Highlights:
- Dual-Rail Output: 24VDC at 4A continuous plus 12VDC at 6A continuous from a single enclosure — eliminates the need for a separate 12VDC converter module in mixed-voltage access control retrofits.
- Per-Circuit Fusing (3A/32V outputs): Individual output fuses mean a wiring fault or device failure takes down one circuit, not the entire distribution board. In a 6-door controller installation this is the difference between one malfunctioning door and a building-wide lockout.
- 7AH Battery Reserve: Sized appropriately for typical 2–4 hour outage bridge at moderate loads — covers most grid brownouts and utility maintenance windows without oversizing to a 12AH or 17AH battery that won't fit the enclosure.
Deployment Considerations:
- The 18" x 14.5" x 4.62" enclosure is wall-mount form factor, not rack-mount — confirm your IDF closet or security room has a clear 18" wide wall section with conduit access before specifying this over a rack-panel variant.
- Operating temperature ceiling is 49°C: in unconditioned electrical rooms in hot climates, verify ambient summer temperatures don't routinely exceed this — sustained operation above 49°C will shorten battery service life even if the supply itself keeps running.
The T1AXK1F4PQ is a well-matched solution for mid-size commercial buildings — a 3- to 6-door access control installation in a single-tenant office, clinic, or light-industrial facility — where you want LINQ visibility across the power plant without the cost and complexity of a full enterprise power management stack.
