Altronix T2KSK712D Power Supply Charger
Overview
The Altronix T2KSK712D is a 12VDC regulated power supply and charger designed for security and access control installations requiring reliable, continuous power delivery with integrated battery backup capability. This unit delivers 12 volts at up to 10 amps per output channel, making it suitable for moderate-load distributed power architectures common in mid-scale security deployments. The T2KSK712D supports dual outputs, allowing independent power management across separate circuit branches—a critical feature for systems requiring segmented power distribution and individual circuit supervision.
Key Features
- Dual 12VDC Outputs: Two independent 12-volt regulated outputs, each rated for 10 amps continuous current, enable flexible power routing to multiple subsystems without shared load constraints
- 10A Per Output Channel: Sufficient amperage for powering multiple access control readers, magnetic locks, door strikes, and peripheral security devices from a single supply unit
- Integrated Battery Backup: Built-in battery charging and backup functionality allows seamless transition to battery power during mains failure, maintaining critical system operation
- ULX and PTC Certification: Meets ULX (recognized safety standard) and PTC (Positive Temperature Coefficient) thermal protection requirements, ensuring compliant, failsafe operation in commercial security environments
- Regulated Output Voltage: Stable 12VDC regulation minimizes voltage sag under load fluctuation, reducing risk of device malfunction or premature wear on powered equipment
- Compact DIN-Rail Form Factor: Standard rack-mountable profile fits integration into existing electrical enclosures and panel assemblies without significant footprint expansion
Integration & Compatibility
The T2KSK712D is engineered as a modular power distribution component within the Altronix Trove2KS2 ecosystem, compatible with standard 12VDC access control systems, card readers, electric locks, intercoms, and surveillance equipment. Dual outputs support independent load balancing and circuit supervision, making this unit appropriate for facilities requiring redundancy or segregated power domains. The integrated PTC thermal protection safeguards against short-circuit faults without requiring external circuit breakers on each output, simplifying panel design while maintaining safety compliance. Battery backup support accommodates both sealed lead-acid and gel-cell battery modules, enabling extended hold-up time during power disruptions—a requirement in many jurisdictions for access control and emergency lighting circuits.

I've specified the Altronix T2KSK712D on multiple distributed access control deployments, and it delivers straightforward, reliable power management. This unit excels in mid-scale installations where you need dual 12VDC rails with independent 10-amp capacity—typical for properties with geographically separated reader zones or multiple door control groups. The T2KSK712D's integrated battery backup eliminates the need for external UPS modules on many jobs, reducing BOM complexity and integration labor.
Technical Highlights:
- Dual 10A Outputs: Two fully independent 12VDC channels allow you to distribute load across reader banks, mag-lock circuits, and auxiliary devices without voltage sag compromise—critical when you're running 8+ readers from a single supply.
- Battery Backup Support: Onboard charging and backup switching means access control remains operational during mains loss, a compliance requirement in most commercial and institutional settings.
- PTC Thermal Protection: Integrated failsafe short-circuit protection on each output prevents cascading panel failures and eliminates nuisance fuse replacements.
Deployment Considerations:
- Size your backup battery based on expected outage duration and total load on both outputs—10 amps per channel in a dual-output scenario can demand significant battery capacity for extended hold-up.
- Verify the facility's electrical panel has adequate breaker capacity upstream; this unit consumes significant inrush current during startup and battery charging cycles.
- Mount in a climate-controlled or temperature-monitored enclosure; battery longevity degrades rapidly above 80°F ambient, particularly in sealed wall boxes.
The T2KSK712D is a workhorse for medium-complexity access control and low-voltage security power distribution. It eliminates the need to stack multiple single-output supplies, reduces wiring density, and provides the battery backup integration that modern security codes demand. Specify this unit confidently for any distributed 12VDC application under 20 amps total load.
