Altronix T2Z7CK1D 10A 8-Door PTC Access Control Power Supply
Overview
The Altronix T2Z7CK1D is a commercial-grade, 115VAC-input power supply engineered to support up to eight access control doors from a single unit. Rated at 10 amps total output, it delivers the sustained current draw that multi-reader installations demand without requiring a separate power distribution board for each door. If you are wiring a mid-size access control deployment — a multi-tenant office floor, a school building wing, or a warehouse entry complex — the T2Z7CK1D is sized to handle the load in a single enclosure.

Key Features
- 10A Total Output: Enough sustained current to drive eight doors with electric strikes or maglocks simultaneously without brownout conditions — typical strike draws run 500mA to 1A, so the 10A budget gives you real headroom for inrush on lock release cycles.
- 8-Door Capacity: Dedicated outputs for up to eight doors from one unit reduces homerun wiring runs and simplifies your panel closet. Fewer power supplies means fewer failure points and less cabinet space consumed. See how this fits into a broader access control system design.
- PTC Overcurrent Protection: Polymer positive temperature coefficient (PTC) protection on outputs automatically limits current during a fault and resets when the overload clears — no blown fuses to swap in the field. This is a meaningful maintenance advantage in remote IDF closets or unmanned entry points.
- 115VAC Input: Standard North American wall power input means no step-down transformer or special outlet is needed. Install it wherever a standard 15A or 20A circuit is available — typical in any commercial building electrical room or IDF closet.
- Commercial-Grade Construction: Altronix builds this unit for continuous 24/7 operation in security applications, not intermittent duty. The T2Z7CK1D is sourced factory-new from the manufacturer with no grey-market or parallel-import risk.
Integration and Compatibility
The T2Z7CK1D is designed to pair with Altronix access control panels and is broadly compatible with third-party panels that accept a centralized power feed. Consult your access control panel documentation for output voltage requirements before wiring. PTC-protected outputs work well with most electric strike and maglock products; verify your lock's inrush spec against the per-output rating. For large deployments, consider pairing with a power distribution or battery backup solution to maintain door function during a power interruption.
Frequently Asked Questions
Q: Is the T2Z7CK1D NDAA Section 889 compliant?
A: The available evidence indicates NDAA compliance is listed as No for this SKU. Verify with your project specifications before specifying for federal or government installations.
Q: What type of overcurrent protection does the T2Z7CK1D use?
A: The T2Z7CK1D uses PTC (Positive Temperature Coefficient) overcurrent protection. PTC devices automatically reset after an overload clears — no fuse replacement required in the field.
Q: What is the input voltage for the T2Z7CK1D?
A: The T2Z7CK1D requires 115VAC input — standard North American single-phase power. No step-down transformer is needed.
Q: How many doors can the T2Z7CK1D support?
A: Up to 8 doors from a single unit, with a 10A total output capacity across all outputs.
Q: Can the T2Z7CK1D be used with third-party access control panels?
A: It is broadly compatible with panels that accept a centralized power feed, but verify the output voltage and current requirements of your specific panel and locking hardware before installation.
The T2Z7CK1D's 10A aggregate output across 8 door outputs is what makes this unit worth specifying on mid-size commercial jobs — it eliminates the per-door power supply approach that bloats your panel closet and multiplies your failure points. On most 8-door installs running standard 12VDC strikes at 500–700mA each, you are drawing 4–6A in steady state, which keeps you comfortably inside the 10A ceiling even with simultaneous lock releases.
Technical Highlights:
- PTC Protection: Auto-resetting overcurrent protection on each output means a shorted strike or miswired lock does not take down the whole board and does not require a service call to swap a fuse — the output recovers once the fault clears.
- 10A / 8-Door Rating: 10A total with 8 discrete outputs gives you roughly 1.25A per door at full load — sufficient for most magnetic locks and electric strikes, though high-current maglocks (600mA–1A peak) should be calculated against the per-output spec from the datasheet.
- 115VAC Input: Standard North American input voltage means the T2Z7CK1D installs directly on a commercial 15A or 20A branch circuit with no additional transformation hardware.
Deployment Considerations:
- Confirm the output voltage and per-output current rating from the Altronix datasheet before wiring high-inrush locking hardware — the 10A total must be budgeted across all 8 outputs, not treated as 10A per door.
- NDAA compliance is listed as No for this SKU — do not specify the T2Z7CK1D on federal projects or any contract requiring Section 889 Part B compliance without substituting a compliant alternative.
The T2Z7CK1D is a practical fit for commercial office, education, or light-industrial deployments where you need centralized, fuse-free power distribution for an 8-door access control build on standard North American power.
