Altronix T2MK1SH1 Dual-Voltage 4A Power Supply 8-Output

Altronix T2MK1SH1 TROVE2M2 Dual-Voltage Power Supply with Battery Backup

Overview

The Altronix T2MK1SH1 is a compact, dual-voltage power supply and charger engineered for distributed security and access control installations. This TROVE2M2 module delivers regulated 12VDC or 24VDC output at 4A, making it suitable for IP camera arrays, door locks, card readers, and auxiliary security devices. The integrated battery backup capability ensures continuity during power interruptions—a critical requirement for access control and life-safety applications in commercial and institutional settings.

Key Features

• Dual Output Voltage Options: Configurable 12VDC or 24VDC output to match legacy and modern device requirements
• 4A Current Rating: Sufficient capacity for up to 8 devices or a mix of higher-draw endpoints depending on load profile
• 8 Isolated Outputs: Separate output distribution for independent load control and isolation
• Battery Backup Integration: Supports rechargeable battery modules for emergency power during AC mains failure
• Regulated Output: Maintains stable voltage under varying load conditions, critical for sensitive electronics and sensor accuracy
• Compact Chassis: Space-efficient form factor designed for in-wall, under-desk, or DIN-rail mounting in crowded electrical closets
• Supervised Output: Output status monitoring for verification of power distribution integrity
• Input Protection: Built-in surge suppression and reverse polarity protection to safeguard against wiring faults and transient events

Integration & Compatibility

The T2MK1SH1 integrates seamlessly into Altronix ecosystem installations, where it functions as a peripheral power module in larger distributed systems. The 8-output architecture permits zone-based power distribution, allowing integrators to segregate door locks, card readers, motion sensors, and auxiliary loads across separate circuits. This modular approach simplifies troubleshooting and reduces the operational impact of individual load failures. Battery backup compatibility enables the device to function as an emergency power node for access control during utility outages, a key requirement in buildings subject to fire code and ADA compliance mandates.

Installation & Operational Notes

The Altronix T2MK1SH1 supports both 12VDC and 24VDC configurations to accommodate mixed-voltage installations common in retrofit and upgrade scenarios. Integrators should verify load current draw against the 4A aggregate rating when designing multi-device circuits. The supervised output feature allows integration with central monitoring systems to flag power distribution faults in real time. Battery charging is managed internally, enabling backup modules to remain trickle-charged and ready for deployment during AC interruptions.

I've specified the Altronix T2MK1SH1 in access control deployments where distributed power is required across multiple zones. The 8-output configuration and dual-voltage flexibility make this a reliable workhorse for integrators managing mixed legacy and modern systems. Battery backup support is essential for life-safety compliance, and the supervised output monitoring integration reduces field service callbacks.

Technical Highlights:

• Dual-Voltage Design: 12VDC or 24VDC output flexibility accommodates both older hardwired systems and contemporary IP devices in the same installation
• 4A Per-Module Capacity: Sufficient for 8 independent loads or grouped endpoints, typical for small-to-medium access control nodes
• Battery-Ready Architecture: Internal charging management and supervised output enable instant switchover during mains loss

Deployment Considerations:

• Verify total load current across all 8 outputs does not exceed 4A per T2MK1SH1 module; install additional modules in series if zone current requirements exceed this threshold
• Use the supervised output feature to integrate with the access control panel or central monitoring system for real-time fault alerting
• Plan battery backup sizing based on hold-up time requirements—access control systems typically require 24–48 hours of emergency power capacity per local fire code

The T2MK1SH1 is ideal for mid-size distributed power applications where compact form factor, redundancy, and voltage flexibility matter. Its straightforward integration and battery support make it a sensible choice for integrators standardizing on Altronix platform solutions.
