Altronix T3V77XK1IT Trove3V Integrated Power Distribution System

The Altronix T3V77XK1IT is a pre-assembled Trove3V power distribution kit engineered for mid-to-large access control and surveillance installations where consolidating power, control, and distribution into a single lockable enclosure saves commissioning time and reduces field wiring errors. It ships with two eFlow104NB power supplies, two ACMS12 dual-input/output fused access power controllers, and three PDS16 dual-input/output fused power distribution modules — all pre-mounted inside a 16 AWG powder-coated steel cabinet.

Overview

Centralizing power distribution in a single enclosure matters on projects where AHJ inspections, cable management, and future serviceability are priorities. The T3V77XK1IT bundles everything needed to power, protect, and distribute 12VDC or 24VDC loads without sourcing components individually. The enclosure accepts up to four 12VDC/12AH batteries, making it suitable for installations requiring local UPS backup. UL, cUL, and CE certifications cover the assembly for commercial deployment across North American and international projects. For broader context on sizing power for camera and access systems, see our surveillance power supplies category.

Key Features

• Dual eFlow104NB Power Supplies: Two independent supplies running in parallel increase available current headroom and provide a degree of redundancy — if one output is loaded heavily, the second shares the burden rather than forcing an undersized single unit.
• Two ACMS12 Access Power Controllers: Each ACMS12 provides 12 individually fused, dual-input/output outputs. Fusing per output means a shorted load takes down only that circuit, not the whole panel — critical on multi-door access deployments where a wiring fault at one reader shouldn't kill the rest of the site.
• Three PDS16 Distribution Modules: Each PDS16 adds dual-input/output fused distribution capacity. With three modules installed, the assembly handles a large number of distributed loads (cameras, readers, locks) while keeping each circuit independently protected.
• Battery Support for Up to Four 12VDC/12AH Units: Local battery backup is installed inside the same enclosure — no external battery cabinet needed. This simplifies UPS compliance documentation and keeps the footprint tight in an IDF or electrical closet.
• 16 AWG Powder-Coated Steel Enclosure: Commercial-grade steel construction with a cam lock and tamper switch. The tamper switch enables monitoring for unauthorized access through a connected panel or controller input — a requirement on many enterprise and government access control specs.
• Flexible Knockout Configuration: One 2.415-inch, two pairs of double 1.95-inch/1.5-inch, and thirteen pairs of double 1.115-inch/1.362-inch knockouts accommodate a range of conduit sizes without field modification. Plan conduit routing before installation — available knockouts are plentiful but their locations are fixed at the factory.
• 120VAC Input: Standard single-phase input works with any commercial building service without a step-down transformer. Confirm your local circuit can sustain the combined inrush of both power supplies under full battery-charge load.
• UL, cUL, and CE Listed: Third-party certification supports AHJ approval on permitted commercial projects and satisfies insurer requirements where UL-listing on power distribution equipment is stipulated. Confirm with your AHJ whether the specific listing type (UL 2044, UL 294, etc.) matches your project's scope.

Integration and Compatibility

The T3V77XK1IT is designed for use with access control systems and IP surveillance infrastructure where 12VDC or 24VDC distributed power is required. The ACMS12 controllers are compatible with Altronix's broader eMerge and NetWay ecosystem. Pair the assembly with a managed PoE switch for IP camera circuits that require 802.3af/at rather than direct DC distribution — the T3V77XK1IT handles the legacy 12/24VDC loads while the PoE switch handles IP endpoints.

Frequently Asked Questions

Q: How many batteries does the T3V77XK1IT support, and what size?

A: The enclosure supports up to four 12VDC/12AH batteries for local UPS backup. Batteries are not included and must be ordered separately.

Q: Is the T3V77XK1IT UL listed?

A: Yes — the assembly carries UL, cUL, and CE certifications. Verify with your AHJ which specific UL listing standard applies to your project type.

Q: What input voltage does the T3V77XK1IT require?

A: It operates on 120VAC — standard single-phase commercial building power. No step-down transformer is required.

Q: Does the enclosure include a tamper switch?

A: Yes. A tamper switch is included and can be wired to a compatible access control panel input to alert on unauthorized enclosure access.

Q: Can I add this enclosure to an existing Altronix eMerge system?

A: The ACMS12 controllers in the T3V77XK1IT are part of the Altronix access power controller family and are compatible with eMerge-based architectures. Confirm specific integration wiring with Altronix technical support for your controller version.

Q: What conduit sizes are supported by the enclosure knockouts?

A: The enclosure includes one 2.415-inch knockout, two double-knockout pairs at 1.95-inch/1.5-inch, and thirteen double-knockout pairs at 1.115-inch/1.362-inch — covering standard 1/2-inch through 1-inch conduit trade sizes.

Jerry Tildsen

The T3V77XK1IT is one of those assemblies that saves real time on a mid-size access control build — specifically because the two ACMS12 controllers give you 24 individually fused dual-output circuits in a single pre-mounted package, which is the kind of per-circuit fault isolation that separates a professional installation from a gang-fused mess. I reach for this kit when a project has 12 or more controlled outputs and the integrator wants everything behind a single cam-locked door with a tamper input wired back to the panel.

Technical Highlights:

• Dual eFlow104NB Supplies: Running two supplies in the same chassis provides current sharing under heavy load — you're not gambling on a single supply sizing margin when the batteries are also charging.
• Per-Circuit Fusing on ACMS12: Each of the 12 outputs per controller is independently fused. A wiring fault at a door strike or reader doesn't cascade — the rest of the site stays up. That's the spec that matters most on a 20-door deployment.
• Battery Bay for 4× 12V/12AH: Built-in battery support inside the steel cabinet means your UPS documentation is straightforward — one enclosure, one listing, no external battery closet required.

Deployment Considerations:

• Plan conduit routes before mounting — the thirteen double-knockout pairs at 1.115-inch/1.362-inch cover most standard trade sizes, but their positions are fixed and the 16 AWG steel enclosure doesn't yield easily to field modification.
• The tamper switch is only useful if it's actually wired to a monitored input — confirm your panel has a spare zone available before specifying this as a tamper-monitored installation point.

This assembly is the right call for commercial office or light-industrial access control builds in the 10-to-20-door range where the integrator needs per-circuit protection, local battery backup, and a UL-listed enclosure — all without sourcing and mounting components individually.
