Altronix T3SK75F16PDQ Dual-Output Surveillance Power Distribution Enclosure
The Altronix T3SK75F16PDQ is a fully integrated, large-format power distribution enclosure engineered for mid-to-large surveillance deployments that demand dual-voltage outputs, granular per-circuit protection, and room to grow. Combining a 24VDC @ 10A supply, a 12VDC @ 10A supply, a 16-circuit PTC-protected distribution board, and an access control module (ACM) in a single 36.12" × 30.125" × 7.06" steel enclosure, this assembly eliminates the wiring maze of multiple standalone power supplies and gives installers a single lockable termination point for an entire riser or IDF closet.
Overview
The T3SK75F16PDQ belongs to Altronix's Altronix TROVE series — pre-integrated enclosures designed to reduce field labor and commissioning time on complex surveillance power distribution projects. Rather than sourcing individual power supplies, distribution boards, and enclosures separately, this kit ships as a tested, populated assembly ready for AC input and camera/device terminations. The steel enclosure carries a CE listing and is sized to accommodate battery backup (12VDC/12AH capacity supported) for ride-through during brief outages — a real advantage on exterior camera runs where even a 30-second power interruption means lost footage.
Key Features
- Dual Independent Outputs — 24VDC @ 10A and 12VDC @ 10A: Running two voltage rails from a single enclosure means you can power 24V PTZ cameras and 12V fixed cameras off the same riser drop without a second unit. Each rail draws from its own transformer and fuse, so a fault on one rail does not collapse the other.
- 16-Circuit PTC-Protected Distribution: Sixteen individually resettable PTC (Positive Temperature Coefficient) overcurrent devices at 2.5A each protect every camera or device run. A shorted cable clears that circuit automatically without blowing a fuse or requiring a truck roll — important on large sites where a single tripped breaker can otherwise darken multiple cameras.
- ACM Output — 24VDC @ dedicated rail: The integrated Access Control Module (ACM) delivers 24VDC at up to 10A (fused at 10A/250V) with its own 2.5A PTC-distributed outputs, making this enclosure compatible with door controllers, electric strikes, and mag-locks on the same backplane. This consolidates access control power alongside camera power in a single secured cabinet — fewer cabinets, fewer code-compliance headaches.
- ACM Relay Output — 28VAC/VDC @ 2.5A: The onboard relay supports dry-contact integration with alarm panels or door hardware. At 2.5A, it handles most electric strike loads directly without an external relay board.
- Battery Backup Support — 12VDC/12AH: Provisions for a 12AH sealed lead-acid battery provide runtime buffer during power interruptions. For a typical 16-camera deployment pulling 500mA per camera, 12AH buys roughly 90 minutes of coverage — enough to bridge most commercial utility outages.
- Auxiliary Outputs — 1A on each main rail: Both the 24V and 12V rails provide a 1A auxiliary output, useful for powering a network switch, audio device, or supplementary sensor without tapping the primary distribution circuits.
- Input Fusing — 6.3A/250V (24V supply) and 5A/250V (12V supply): Separate input fuses on each supply protect upstream wiring independently. The lower 5A fuse on the 12V side reflects the different load profile — sized correctly from the factory rather than over-fused.
- Large-Format Steel Enclosure — 36.12" × 30.125" × 7.06": The enclosure's depth (7.06") accommodates battery modules, terminal blocks, and a full complement of cable management without crowding. At 84.2 lb. shipped weight, plan for two-person installation; wall anchoring to studs or uni-strut is required given the fully loaded mass.
- CE Listed: European Conformity listing confirms the assembly meets EU safety and EMC directives — relevant for projects with international compliance requirements or multi-region enterprise rollouts.
- Operating Range 0°C to 49°C: Rated for standard indoor mechanical room and IDF closet environments. This is not a rated outdoor enclosure — deploy in a conditioned or semi-conditioned space.
Integration and Compatibility
The T3SK75F16PDQ is designed to integrate into structured surveillance and access control architectures where a centralized power point simplifies commissioning and ongoing maintenance. The dual-voltage output supports mixed camera fleets common in enterprise upgrades where 24V IP cameras sit alongside legacy 12V analog or lower-cost fixed cameras. The ACM's 24VDC output and relay are compatible with most commercial door controller panels that accept 24V regulated input. Because all outputs are derived from a 120VAC/60Hz single-phase input (fused at the entry point), this enclosure is wired to a standard 15A or 20A circuit — confirm available panel capacity before specifying on sites with constrained electrical infrastructure. For projects requiring PoE-based camera power, note this enclosure provides conventional DC distribution, not PoE; pair it with a managed PoE switch for IP cameras that do not accept direct DC input.
Frequently Asked Questions
Q: Can the T3SK75F16PDQ power both 24V and 12V cameras from the same enclosure simultaneously?
A: Yes. The enclosure provides two independent output rails — 24VDC @ 10A and 12VDC @ 10A — each with its own input fuse and transformer. Both rails operate simultaneously, so a mixed camera fleet drawing from different voltage rails is fully supported without any cross-interference between supplies.
Q: What battery does this enclosure support, and how long will it run on backup?
A: The T3SK75F16PDQ supports a 12VDC/12AH sealed lead-acid battery for backup. Runtime depends on load — a 16-camera deployment at roughly 500mA per camera yields approximately 90 minutes of backup. Heavy loads (multiple PTZ cameras plus door hardware) will reduce that estimate; factor actual current draw during system design.
Q: Does this unit include access control power, or is that a separate enclosure?
A: Access control power is integrated. The ACM (Access Control Module) provides a dedicated 24VDC output fused at 10A/250V with 2.5A PTC-protected circuits plus a relay rated at 28VAC/VDC @ 2.5A for door hardware — all within the same enclosure as the camera power supplies.
Q: What certifications does the T3SK75F16PDQ carry?
A: The enclosure carries CE (European Conformity) listing per the verified agency listings for this SKU. Confirm with your authority having jurisdiction (AHJ) whether additional local listings are required for your specific installation.
Q: Is the T3SK75F16PDQ suitable for outdoor installation?
A: No. The rated operating temperature range is 0°C to 49°C and the enclosure is a standard steel cabinet without an outdoor IP or NEMA weatherproof rating. Install in a conditioned or semi-conditioned indoor space such as an IDF closet, mechanical room, or security head-end.
Q: How many PTC-protected circuits does the distribution board provide?
A: The board provides 16 individually resettable PTC circuits, each rated at 2.5A. A fault on any single circuit resets automatically without manual fuse replacement, which reduces service calls on large deployments where a shorted cable run would otherwise require on-site intervention.
The T3SK75F16PDQ is the enclosure I specify when a project has both surveillance and access control on the same riser and I need to keep the head-end cabinet count down. The dual-rail design — 24VDC @ 10A and 12VDC @ 10A running simultaneously from a single 120VAC feed — handles mixed camera fleets without the voltage-adapter clutter that accumulates when integrators try to adapt one supply to two voltage requirements.
Technical Highlights:
- 16-Circuit PTC Distribution at 2.5A each: Self-resetting overcurrent protection on every run means a field tech doesn't need to carry spare fuses or make a return visit for a tripped circuit. On a 64-camera campus with four of these enclosures, that translates to real operational savings over a service contract lifecycle.
- Integrated ACM — 24VDC @ 10A with relay at 28VAC/VDC @ 2.5A: The access control module handles most small-to-mid door controller loads directly. The 2.5A relay rating covers the majority of commercial electric strikes without an outboard relay board — one fewer component to wire and troubleshoot.
- Battery Backup — 12VDC/12AH: A 12AH battery in this enclosure buys meaningful bridge time. At a conservative 8A total load across cameras and door hardware, you're looking at roughly 60–75 minutes of ride-through — enough to outlast most utility blips without NVR gaps.
Deployment Considerations:
- At 84.2 lb. unloaded (97.5 lb. shipped), this cabinet needs two installers and solid anchor points — uni-strut rail or plywood backer rated for the weight. Do not single-man this mount.
- The 0°C to 49°C operating range means this enclosure is strictly indoor. If your IDF or mechanical room regularly hits the high end of that range in summer, verify HVAC capacity before committing to this location — the unit itself generates 217 BTU/Hr at full load, which matters in a small, poorly ventilated closet.
This enclosure is the right call for mid-size commercial buildouts — think a 16–32 camera corporate campus or a multi-tenant retail center where a single head-end cabinet per floor consolidates camera power, door control, and backup in one auditable, lockable point.
