Altronix T2SAK7512D Dual-Voltage Supervised Power Supply

Altronix T2SAK7512D Supervised Power Supply

The Altronix T2SAK7512D is a dual-voltage supervised power supply designed for security systems requiring reliable 12VDC and 24VDC distribution with integrated battery charging and output supervision. This model delivers 20 amps at both 12VDC and 24VDC, making it suitable for mid-scale access control, CCTV, and intrusion detection installations that demand redundancy and real-time system monitoring.

Overview

Built for professional integrators, the T2SAK7512D combines primary DC power distribution with supervised output monitoring and battery backup capability. The unit operates from standard AC mains and provides selectable dual-voltage output, allowing a single device to power mixed 12V and 24V loads. Supervision circuits monitor each output for ground faults, loss of power, and battery status, generating relay alerts for integration with control panels and SCADA systems. This eliminates the need for separate power supplies and supervision modules in many installations.

Key Features

• Dual-Voltage Output: Selectable 12VDC or 24VDC operation accommodates legacy and modern equipment on the same circuit
• 20A Current Rating: Sufficient capacity for small-to-medium camera arrays, access control readers, and door strikes
• Supervised Outputs: Built-in ground fault and power-loss supervision with relay notification for alarm reporting
• Battery Charging: Integrated charger supports lead-acid battery backup for emergency egress and critical circuits during AC loss
• UL Listed: Meets UL 2044 standard for power supplies used in security applications
• Compact Form Factor: DIN-rail or wall-mount installation compatible with standard enclosures
• Fused Output Protection: Factory-installed fusing prevents downstream short-circuit damage
• Industry-Standard Connectors: Screw terminals for reliable field termination and quick troubleshooting

Integration & Compatibility

The T2SAK7512D integrates directly into access control panels, video management systems, and alarm receivers via its supervised output relay contacts. The model supports common 12V and 24V DC loads including electromagnetic locks, motion detectors, power over Ethernet injectors, and traditional CCTV cameras. Battery backup operation allows critical circuits—such as door release mechanisms and alarm reporting—to remain active during AC power interruptions, meeting lifecycle safety and code compliance requirements.

Package Contents

Unit arrives complete with integrated fuse protection, screw terminal blocks for AC input and DC output, supervision relay connectors, and battery charging leads. No external supervision module, relay board, or charging module is required.

Karl Wilson

The Altronix T2SAK7512D addresses a common integration challenge: managing dual-voltage equipment in a single installation without multiplying power supplies, fuses, and supervision points. In my experience deploying mixed legacy and modern access control systems, this dual-output approach reduces panel clutter and simplifies maintenance—fewer components mean fewer failure modes.

Technical Highlights:

• Supervised Outputs: Ground fault and power-loss detection on each rail eliminates the need for external supervision modules and provides immediate alert capability for monitoring systems
• Battery Integration: Built-in charger simplifies backup power design; no external charging relay or module required for lead-acid systems
• 20A Capacity: Adequate for 8–12 standard security cameras or 6–8 access readers per output, matching typical small-to-medium site requirements

Deployment Considerations:

• Verify load polarity and total amperage on each voltage rail before installation; mixed-load configurations must account for charger current draw during battery operation
• Mount the T2SAK7512D within 50 feet of the battery to minimize voltage drop and charging inefficiency in distributed backup systems
• Configure alarm receiver or control panel to monitor the supervision relay output for real-time fault notification and audit compliance

For integrators building modular, code-compliant security systems, this unit delivers the supervision and backup power essentials in a single enclosure form factor. Recommended for facilities ranging from small commercial to light industrial.
