Altronix T2PHK77F24DV 24-Door Access Control Power Distribution Kit
Overview
The Altronix T2PHK77F24DV is a fully integrated power distribution kit engineered for large-scale access control deployments requiring centralized 24VDC power management across up to 24 doors. Designed as a bundled TROVE2 enclosure assembly, the T2PHK77F24DV packages the power supply board, distribution hardware, and PTC overcurrent protection into a single pre-configured system — eliminating the field-integration headaches that come with sourcing and wiring these components separately. At 53.55 lbs and 6.50 x 21.50 x 27.25 inches, this is a panel-room or electrical-closet installation, not a wall-corner box. If you're commissioning a mid-to-large enterprise access system with 12 to 24 controlled openings, this kit is built to match that scope.

Key Features
- 24VDC / 10A Output: A 10-amp continuous output at 24 volts gives you enough headroom to power electric strikes, magnetic locks, and associated control hardware across a 24-door system without relying on distributed local power supplies at each door — simplifying your infrastructure and your service calls. That centralization also makes load monitoring and troubleshooting significantly faster.
- 24-Door Capacity: Supporting up to 24 independent door outputs from a single enclosure means fewer panels, fewer cable runs back to a central room, and a cleaner as-built drawing. For enterprise campuses, hospital wings, or multi-floor commercial builds, consolidating power here reduces the per-door installed cost meaningfully.
- PTC Overcurrent Protection: Polymeric PTC (Positive Temperature Coefficient) devices reset automatically after an overcurrent event — no fuses to replace in the field when a door controller faults or a wiring short trips protection. In a 24-door system, a resettable fault on one output prevents a service call from turning into a parts order, and means the rest of the doors keep running during the event.
- 220V Input: The 220V AC input configuration makes this kit appropriate for international deployments or domestic installations where 220V circuits are available in the panel room — a common scenario in industrial facilities and certain commercial builds. Verify your local circuit availability before specifying; this is not a 120V unit.
- Pre-Configured TROVE2 Enclosure Assembly: The TROVE2 platform integrates power and access control hardware into a structured enclosure system. By ordering the T2PHK77F24DV as a kit, you receive components pre-matched for the enclosure footprint, reducing assembly time on site and the risk of selecting incompatible board/enclosure combinations.
- 53.55 lb Integrated Assembly: The weight reflects a fully equipped, rack-capable enclosure — not a lightweight board. Plan for two-person installation and appropriate wall or rack anchoring rated for the load. At 27.25 inches tall and 21.50 inches wide, confirm your IDF/MDF or dedicated panel room has the clearance before delivery.
Integration & Compatibility
The T2PHK77F24DV is designed for deployment within Altronix's TROVE2 enclosure ecosystem, pairing with access control panels that operate on 24VDC power inputs. It is well-suited to integrate with leading access control systems that require centralized power distribution — including multi-reader controllers from manufacturers who specify 24VDC at the panel level. Confirm your access control panel's per-door current draw against the 10A total output; at 24 doors, average per-door budget is approximately 416mA, which is sufficient for most electric strikes and mag-locks under standard hold-force specs, but verify any door with high-draw hardware (e.g., high-force mag-locks rated above 300mA continuous).
When designing the power architecture for a large deployment, pair this kit with a structured access control power supply planning review to ensure battery backup capacity, circuit protection coordination, and code compliance are addressed holistically. For sites requiring PoE-based reader power, a separate PoE switch will handle reader-side power; the T2PHK77F24DV covers locking hardware and panel power, not data-layer PoE.
Frequently Asked Questions
Q: What input voltage does the T2PHK77F24DV require?
A: The T2PHK77F24DV is configured for 220V AC input. It is not a dual-voltage or 120V unit. Confirm your panel room has an available 220V circuit before specifying this kit.
Q: How many doors can the T2PHK77F24DV support?
A: The T2PHK77F24DV supports up to 24 doors, with 24VDC output at 10A total across all outputs.
Q: What type of overcurrent protection does the T2PHK77F24DV use?
A: It uses PTC (Polymeric Positive Temperature Coefficient) protection, which is self-resetting — no fuse replacement required after an overcurrent event clears.
Q: What are the physical dimensions and weight of the T2PHK77F24DV?
A: The enclosure measures 6.50 x 21.50 x 27.25 inches and weighs 53.55 lbs. Plan for two-person installation and confirm clearance in your panel room before delivery.
Q: Is the T2PHK77F24DV compatible with third-party access control panels?
A: The T2PHK77F24DV provides 24VDC power distribution, which is a standard voltage for many commercial access control panels. Compatibility depends on your panel's input voltage and per-door current requirements. Verify specifications with your access control panel manufacturer before deployment.
Q: Does the T2PHK77F24DV include battery backup capability?
A: Battery backup capability is not confirmed in available evidence for this kit configuration. Consult Altronix documentation or your distributor to clarify backup provisions for the TROVE2 platform assembly included in this kit.
The T2PHK77F24DV is one of those kits that earns its keep specifically when you're staring down a 20-plus-door deployment and don't want to piece together a power architecture from loose components. The 10A at 24VDC output — distributed across 24 door outputs with PTC protection on each — is the right spec for a hospital wing, a corporate campus access retrofit, or a government facility where you need centralized, auditable power infrastructure rather than a patchwork of local supplies at each door controller closet.
Technical Highlights:
- 10A / 24VDC Output: Provides approximately 416mA average per door across 24 outputs — comfortably within range for most electric strikes (typically 250–500mA) and standard mag-locks, while keeping total draw on one centralized supply.
- PTC Overcurrent Protection: Self-resetting PTC devices mean a shorted door output doesn't require a truck roll for fuse replacement — the fault clears and the protection resets, keeping the other 23 doors unaffected during the event.
- 220V Input Configuration: Positions this kit for international projects or domestic industrial facilities where 220V panel circuits are the norm, avoiding the need for step-down transformers that add cost and failure points.
Deployment Considerations:
- At 53.55 lbs and 27.25 inches tall, this is a two-person lift into a dedicated panel room or IDF — site survey the available wall space and confirm mounting surface load rating before scheduling delivery.
- The 10A total output budget across 24 doors is tight if any of your doors use high-force electromagnetic locks drawing 500mA or more continuously — audit your per-door current loads before finalizing the design, and consider whether battery backup capacity needs to be specified separately for this assembly.
The T2PHK77F24DV makes the most sense on a new construction or major renovation project where the panel room is being built to spec — you get the full benefit of centralized power management, clean enclosure integration, and PTC protection without the compromise of retrofitting mismatched hardware into an existing closet.
