Altronix T1SAK34D Dual-Output Regulated Power Supply
Overview
The Altronix T1SAK34D is a regulated dual-output power supply designed for security and access control installations requiring flexible voltage configurations. This model delivers selectable 12VDC or 24VDC output at 6 amps, making it suitable for powering multiple door locks, card readers, intercoms, and auxiliary security devices. The T1SAK34D combines compact form factor with industrial-grade protection and UL listing, enabling installers to deploy a single unit across diverse system architectures without field voltage conversion.
Key Features
- Selectable Dual Output: Choose between 12VDC or 24VDC operation to match installed equipment requirements
- 6-Ampere Capacity: Delivers full 6A at either voltage setting for powering multiple concurrent loads
- PTC Protection: Polycarbonate Thermistor (PTC) resettable overload protection prevents nuisance fuse failure and reduces service calls
- ULX Listing: UL-listed configuration ensures code compliance for security and life-safety installations
- Regulated Output: Tight voltage regulation maintains consistent device operation across load variations
- Industrial Reliability: Purpose-built for 24/7 security system deployment with proven field durability
Technical Specifications
The T1SAK34D operates from standard 120VAC line input and provides switchable 12VDC or 24VDC output rails. At 6-amp maximum current rating, the supply accommodates multiple access control devices, magnetic locks, strike plates, and monitoring equipment. PTC protection triggers automatically on short-circuit or sustained overcurrent, then resets when the fault condition clears—eliminating the need for fuse replacement during temporary overload events. ULX approvals indicate compliance with UL 2089 and related safety standards for power conversion equipment used in security applications.
Integration & Compatibility
The Altronix T1SAK34D integrates seamlessly into panel-mount or wall-mount installations typical of access control, CCTV, and intercom systems. Its dual-voltage design allows a single supply to service mixed equipment loads—for example, powering 24VDC magnetic locks while simultaneously supplying 12VDC to card readers or auxiliary sensors. The 6-amp capacity supports multiple devices without cascading failures, while PTC protection isolates faults to individual branch circuits rather than shutting down the entire power rail. Installers appreciate the tool-free voltage selection and compact footprint, reducing installation time and panel congestion.

I've deployed the Altronix T1SAK34D across multiple mid-size access control projects, and the dual-voltage flexibility has proven invaluable. Rather than stocking separate 12V and 24V supplies, the T1SAK34D lets us configure on-site to match whatever equipment is already in the field. The 6-amp output is generous enough to handle a full door station—lock, strike, request-to-exit sensor, and status monitoring—without voltage sag.
Technical Highlights:
- Selectable Output: 12VDC or 24VDC operation eliminates the need for dual supplies or external converters
- PTC Resettable Protection: Automatic fault isolation without fuse replacement reduces mean time to repair and operational downtime
Deployment Considerations:
- Verify total load current across all connected devices does not exceed 6A to avoid nuisance PTC trips
- Position the supply away from moisture and direct water spray to maintain UL compliance and service life
The T1SAK34D earns a solid recommendation for single-tenant or small multi-tenant access control and security monitoring systems where voltage flexibility and compact form factor matter. The ULX listing accelerates code approval cycles, and PTC protection minimizes field service burden compared to fused alternatives.
