Altronix T2RZ7CK1D Rack Mount Power Distribution Module

Overview

The Altronix T2RZ7CK1D is a rack-mounted power distribution module engineered for multi-door access control installations that need centralized, structured power delivery in a 1U or 2U rack footprint. Accepting 115 VAC input and converting it to a regulated 24 VDC output at up to 10A, this unit is purpose-built for powering door strikes, magnetic locks, and access control peripherals across up to 8 door positions from a single chassis — the kind of consolidation that separates a clean rack from a spaghetti-wired closet. If you're standardizing on Altronix power distribution across a multi-reader deployment, the T2RZ7CK1D fits naturally within that ecosystem.

Key Features

• 24 VDC Regulated Output: Delivers a stable 24-volt output that matches the operating voltage of the majority of commercial door hardware — mag-locks, electric strikes, and access control boards — meaning you're not adding voltage regulators or dealing with compatibility mismatches at each door.
• 10A Total Output Current: At 10 amps available across the distribution points, the T2RZ7CK1D can handle the simultaneous inrush current of multiple door-release cycles without drooping voltage at individual outputs. For context, a typical mag-lock draws 500mA–600mA, so this unit can support up to 16 mag-locks theoretically — though 8-door configurations keep you well inside safe operating margins.
• 8-Door Distribution Architecture: Power is distributed across 8 individually managed outputs, allowing each door to be independently controlled or monitored without cross-contamination of power events. A fault or surge on one door circuit doesn't cascade to the remaining 7.
• PTC (Positive Temperature Coefficient) Overcurrent Protection: Self-resetting PTC protection on the outputs eliminates manual fuse replacement after an overcurrent event. When a door device shorts or draws excessive current, the PTC trips and automatically resets once the fault clears — a meaningful operational advantage in unmanned IDF closets.
• 115 VAC Input: Connects directly to standard North American branch circuits — no step-down transformer, no special outlet. That keeps installation straightforward and compatible with any standard rack PDU or wall circuit.
• Rack Mount Form Factor: Designed to seat into a standard 19-inch equipment rack alongside NVRs, network switches, and access control panels. Centralizing power in the rack reduces cable runs to door hardware (when the rack is in the IDF adjacent to the doors) and makes annual audits and troubleshooting faster.
• Altronix ZK Series Integration: The T2RZ7CK1D is part of Altronix's rack-based power ecosystem, designed to pair with Altronix access control and power management products for cohesive infrastructure — relevant if you're building a standardized rack stack across multiple sites.

Integration and Compatibility

The T2RZ7CK1D's 24 VDC output is compatible with the broad category of commercial access control hardware that runs on 12–24 VDC, including panel-driven door strikes, fail-safe and fail-secure mag-locks, and REX devices. It is intended for use with Altronix access control access control systems and fits within a broader rack power distribution strategy for multi-door deployments. Integrators building out structured cabling and power architectures will find it complements managed network switches in the same rack when running PoE-based readers alongside 24VDC door hardware. For large-scale deployments, review the access control system buying guide to confirm power budgeting across door counts before specifying. If your door count exceeds 8 or your total current draw approaches or exceeds 10A, Altronix offers higher-capacity modules in the same rack-mount family — evaluate those before over-provisioning a single T2RZ7CK1D.

Frequently Asked Questions

Q: What input voltage does the T2RZ7CK1D require?

A: The T2RZ7CK1D accepts 115 VAC input, compatible with standard North American branch circuits. No step-down transformer or special outlet is required.

Q: What is the output voltage and maximum current of the T2RZ7CK1D?

A: It outputs 24 VDC at up to 10A total across all distribution points.

Q: How many doors can the T2RZ7CK1D power?

A: The module is designed to distribute power across up to 8 door positions, each with individually managed outputs.

Q: Does the T2RZ7CK1D have overcurrent protection?

A: Yes. The T2RZ7CK1D includes PTC (Positive Temperature Coefficient) self-resetting overcurrent protection on its outputs. Unlike standard fuses, PTCs automatically reset after a fault clears without manual intervention.

Q: Will the T2RZ7CK1D fit in a standard 19-inch equipment rack?

A: Yes, it is designed as a rack-mount module for standard 19-inch equipment racks, suitable for installation alongside NVRs, switches, and access control panels.

Q: Is the T2RZ7CK1D compatible with magnetic locks and electric strikes?

A: Yes. Its 24 VDC output is the standard operating voltage for the majority of commercial door hardware including mag-locks, electric strikes, and access control peripherals.

The T2RZ7CK1D is the unit I reach for when a project calls for 8-door rack-centralized power with self-resetting PTC protection — specifically because those PTCs eliminate the service call that a blown fuse in an unmanned IDF would otherwise generate. At 10A on 24 VDC, this module has comfortable headroom for a full 8-door mag-lock build without pushing the current budget.

Technical Highlights:

• 24 VDC / 10A Output: Supports up to 8 simultaneous door hardware loads without voltage sag — at typical mag-lock draws of 500–600mA, you have substantial margin even with inrush peaks during simultaneous door-release events.
• PTC Overcurrent Protection: Self-resetting protection means a shorted strike or wiring fault clears itself once the load is removed — no manual fuse swap, no truck roll to an unmanned closet at 2 AM.
• 115 VAC Input / Rack Mount Form Factor: Drops into any standard 19-inch rack on a normal branch circuit, making it straightforward to integrate alongside access control panels and network gear without separate power conditioning.

Deployment Considerations:

• Budget your door-hardware current draws before specifying — if mag-locks, REX devices, and panel boards together approach or exceed 10A, step up to a higher-capacity Altronix module rather than running the T2RZ7CK1D near its ceiling continuously.
• This module outputs 24 VDC only — if your access control readers or panels require 12 VDC, you'll need separate power or a voltage converter; don't assume 24V compatibility across all hardware in a mixed deployment.

The T2RZ7CK1D is a strong fit for mid-size commercial office or education builds with 4–8 controlled doors, where a clean rack-based infrastructure is the standard and the facilities team expects self-resolving fault behavior rather than manual intervention on power events.
