Altronix T2SH7CK1PDQ Pre-Wired Surveillance Power Distribution Center
Overview
The Altronix T2SH7CK1PDQ is a factory pre-wired surveillance power distribution center integrating a regulated 24VDC main output at 9.4A with an 8A auxiliary output — purpose-built for mid-to-large commercial camera installations where clean, supervised power delivery and minimal field wiring time are both requirements. The pre-wired configuration ships with the ACMS8 access control module and LINQ8PD power distribution module already assembled inside a 27.25" x 21.5" x 6.5" enclosure, reducing installation labor significantly compared to building the same stack from discrete components on-site. If you manage installations across multiple sites or run a service department that commissions several systems per month, the T2SH7CK1PDQ's pre-wired format is where the real value shows up — techs open the enclosure, land their field runs, and leave.

Key Features
- Main Output: 24VDC @ 9.4A regulated (20.17–26.4 VDC range): 9.4A of regulated 24VDC is sufficient to drive 8–12 standard 24VAC/DC cameras simultaneously depending on load profile. The tight 20.17–26.4 VDC regulation band keeps analog and IP cameras within spec even during input fluctuations — important in commercial buildings where 120VAC line voltage can swing noticeably during HVAC cycling.
- Auxiliary Output: 8A @ 20.28–26.4 VDC: The auxiliary rail gives you a separate supervised output for readers, door hardware, or a secondary camera zone — keeping access control loads isolated from the primary camera feed reduces noise coupling and simplifies circuit troubleshooting when a device faults.
- Input: 120VAC 60Hz with 6.3A/250V fuse protection: Standard North American line input means no step-down transformer needed. The 6.3A input fuse is sized to protect upstream branch circuit wiring — if downstream loads exceed rated capacity, the fuse clears before the branch circuit breaker, preserving the rest of the panel.
- ACMS8 with 2.5A output fusing per channel: Individual 2.5A fuses on each ACMS8 output mean a shorted camera or reader takes down only its own circuit, not the entire power supply. This is the correct architecture for multi-tenant or multi-zone installations where one failed device should never black out an adjacent zone.
- LINQ8PD with 15A/32V output fusing and 3A/32V input fusing: The LINQ8PD's 15A output fuse rating supports higher-draw devices like PTZ cameras, IR illuminators, or PoE injectors drawing from 24VDC. The 3A input fuse provides coordination protection at the module level — the module clears before the main supply fuse under a LINQ8PD-side fault.
- Battery backup fusing: 15A/32V: The 15A battery fuse is sized for sealed lead-acid backup batteries typically used in commercial surveillance systems. A properly rated battery fuse prevents thermal runaway current from a shorted battery from damaging supply components — a detail that matters for code-compliant UL-listed installations.
- Enclosure: 27.25" x 21.5" x 6.5": The cabinet depth of 6.5" accommodates standard conduit knockouts and leaves room for cable management dressing — adequate for 8-camera homerun terminations without bundling conductors so tightly they generate heat. Wall-mount footprint is consistent with a standard 2-gang backbox column, so it fits in IT closets and security rooms without consuming rack space.
Integration & Compatibility
The T2SH7CK1PDQ is designed for integration into commercial surveillance power distribution architectures where 24VDC analog or hybrid IP cameras are the primary load. The ACMS8 module supports access control readers and door hardware on the auxiliary rail — pairing this unit with a compatible access control panel eliminates the need for a separate power supply dedicated to door hardware, reducing enclosure count and simplifying the power audit during inspection. For larger deployments requiring PoE camera support, pair with a managed PoE network switch for IP camera runs while using this unit to carry legacy 24VDC analog or hybrid cameras. Consult the Altronix LINQ8PD module documentation for device compatibility across the auxiliary distribution rail. For system design guidance, refer to a surveillance system power planning guide covering load calculation, battery backup sizing, and zone isolation best practices.
Frequently Asked Questions
Q: What is the total combined output current of the T2SH7CK1PDQ?
A: The main output delivers 24VDC at 9.4A, and the auxiliary output delivers up to 8A in the 20.28–26.4 VDC range. These are separate regulated rails — do not add them as a single combined figure when calculating load, as each rail has independent fusing and regulation.
Q: Does the T2SH7CK1PDQ support battery backup?
A: Yes. The unit includes a 15A/32V battery fuse, which indicates onboard battery charging and backup circuitry compatible with sealed lead-acid batteries. Battery capacity and runtime depend on connected load — size the battery to your calculated amp-hour requirement based on the total draw across all connected devices.
Q: How many camera outputs does the ACMS8 module provide?
A: The ACMS8 module provides 8 individually fused outputs, each rated at 2.5A. This supports up to 8 separately fused device circuits — cameras, readers, or other 24VDC loads — with per-circuit fault isolation.
Q: What input voltage does the T2SH7CK1PDQ require?
A: The unit requires 120VAC at 60Hz — standard North American single-phase power. No step-down transformer is required for US commercial installations.
Q: What are the enclosure dimensions for rough-in planning?
A: The enclosure measures 27.25" wide x 21.5" tall x 6.5" deep. Plan wall blocking and conduit stub-outs accordingly — the 6.5" depth requires a clear mounting surface free of obstruction behind the cabinet.
Q: Is the T2SH7CK1PDQ compatible with Altronix LINQ management systems?
A: The unit ships with the LINQ8PD module pre-wired, which is part of the Altronix LINQ ecosystem. Verify with Altronix documentation or a pre-sales engineer whether your target LINQ network management platform is compatible with the LINQ8PD variant included in this assembly.
The T2SH7CK1PDQ earns its place on commercial surveillance projects where the alternative is hand-assembling a power stack from loose modules on-site. The pre-wired ACMS8 and LINQ8PD combination arriving in a single 27.25" x 21.5" enclosure cuts commissioning time measurably — the main 24VDC rail at 9.4A is ready to carry a full 8-camera zone the moment field conductors are landed, with no inter-module wiring for the tech to sort out.
Technical Highlights:
- Main Rail Regulation (20.17–26.4 VDC): The regulated output band keeps 24VDC cameras in spec even under building voltage fluctuations — unregulated supplies can push cameras outside their input tolerance during load swings, which shows up as reboots or image artifacts mid-shift.
- Per-Circuit ACMS8 Fusing at 2.5A: Eight independently fused 2.5A outputs mean a shorted camera clears its own circuit and leaves the remaining 7 devices running. In multi-tenant buildings where a camera short during business hours is unacceptable, this architecture is the correct choice over unfused distribution blocks.
- Battery Fuse at 15A/32V: The 15A battery fuse is correctly rated for the sealed lead-acid batteries used in 24-hour surveillance backup schemes — it provides coordinated overcurrent protection that clears before supply-side components are damaged in a battery fault scenario.
Deployment Considerations:
- The 6.5" enclosure depth requires planning during rough-in — verify the mounting wall has sufficient backing depth and that conduit entry knockouts align with your homerun routing before the enclosure is bolted in place.
- The LINQ8PD input fuse is rated 3A/32V, which limits the total input draw to the LINQ8PD module to 3A — confirm your LINQ8PD-connected device load stays within this figure or you risk nuisance fuse clears under normal operating conditions.
This unit is the right fit for commercial retail or campus surveillance closets running 8-zone 24VDC camera systems with a mix of cameras and access readers on the same supply — particularly where the integrator needs to minimize on-site wiring time without sacrificing per-circuit fault isolation.
