Description

Altronix TM400K3 Power Distribution Module

Overview

The Altronix TM400K3 is a compact power distribution module designed to provide reliable, fused power for access control systems, particularly those managing 2 to 3 doors. It accepts a standard 115V AC input and delivers a total of 4 Amperes across four individually fused outputs. This unit is crucial for ensuring each access point receives stable, protected power, preventing cascading failures and simplifying wiring in multi-door installations.

Compatibility

This module is designed for use with access control systems that require individual fused power outputs for door controllers, electric strikes, or magnetic locks. Its 4A total output capacity is suitable for systems with moderate power demands per door. The 115V AC input is standard for North American installations. It is UL Listed, indicating compliance with safety standards for integration into commercial security and access control infrastructure.

Installation Notes

The TM400K3 requires a standard 115V AC power source. Each of the four outputs is protected by a user-replaceable fuse, allowing for isolation of faults to a single device or door. Proper wiring practices for 115V AC and low-voltage DC outputs must be followed. Ensure adequate ventilation around the unit to prevent overheating, especially under continuous load.
