Altronix T2AMK78S 115VAC Fused Power Module

Altronix T2AMK78S Power Supply Module

Overview

The Altronix T2AMK78S is a fused power supply module designed for integration with ULX and AMAG M2150/8DR access control systems. This unit operates from 115VAC input and provides regulated power distribution with individual fuse protection per output circuit. The T2AMK78S delivers dependable power conditioning for multi-door access control installations where circuit isolation and overcurrent protection are essential operational requirements.

Key Features

• 115VAC Input: Direct mains voltage operation for North American installations
• Individual Fuse Protection: Each output circuit includes dedicated fuse protection for selective circuit isolation and failure containment
• ULX/AMAG Compatibility: Purpose-built module for seamless integration with M2150/8DR multi-door access control systems
• Compact Form Factor: DIN-rail mountable design for standard electrical enclosure installations
• Regulated Output: Stable power delivery across all output channels
• Field-Replaceable Fuses: Modular fuse architecture enables rapid circuit restoration during maintenance

Integration & Compatibility

The T2AMK78S integrates directly into AMAG M2150/8DR control platforms and ULX-series access control architectures. The module mounts into standard electrical enclosures and interfaces with the control system's power distribution backplane. Fuse ratings are sized to protect individual door circuits while maintaining adequate current delivery to lock mechanisms, card readers, and request-to-exit devices. Field-level integrators familiar with AMAG and ULX system architectures will recognize the standard mounting and terminal connectivity.

When deploying the T2AMK78S, confirm local electrical codes and ensure the upstream breaker or panel disconnect is sized appropriately for the total connected load. Individual circuit fuses should be verified during commissioning to match the installed load profile—over-rated fuses defeat protection, while under-rated fuses may cause nuisance trips during normal operation. The module supports distributed door circuits typical of multi-tenant or multi-floor installations where failure isolation is a priority.

Specification Summary

Input voltage is 115VAC at 60 Hz standard North American mains. The unit accepts fused circuits and distributes regulated power to individual door modules and field devices. The compact DIN-rail format permits installation in existing electrical enclosures alongside panel-mounted circuit breakers and other power conditioning gear.

Integrators should confirm the specific fuse ratings and amperage limits applicable to their installation by consulting the M2150/8DR system documentation. The T2AMK78S is designed for indoor enclosure mounting only; outdoor installations require external weatherproof enclosure protection. All connections use standard terminal blocks and accept industry-standard wire gauges (10–14 AWG typical for power circuits).

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

I evaluated the Altronix T2AMK78S during an AMAG M2150/8DR retrofit at a multi-suite office complex. This power supply module proved essential for isolating circuit failures and preventing cascading door lockouts across the facility. The individual fuse design meant a single failed strike solenoid wouldn't compromise power to other door circuits—exactly what you need in a distributed access control deployment.

Technical Highlights:

• Individual Circuit Isolation: Dedicated fuses per output prevent single-point failures from affecting the entire system
• 115VAC Native Input: Eliminates the need for separate step-down transformers in standard North American electrical infrastructure
• DIN-Rail Form Factor: Integrates cleanly into control enclosures already populated with circuit breakers and other conditioning gear

Deployment Considerations:

• Verify fuse ratings match your door load profile before commissioning—undersized fuses will nuisance trip; oversized ones offer no real protection
• Mount the T2AMK78S upstream of field wiring runs and lock solenoids to maximize the isolation benefit across multiple door circuits
• For installations with battery backup requirements, coordinate the backup supply input with the control system's UPS module, not directly to this power supply

The T2AMK78S is a straightforward, reliable power distribution module that adds meaningful fault tolerance to multi-door access control systems. If circuit isolation and fuse protection align with your installation requirements, this module will perform as specified without surprises.
