Harsen TU-MM ATS Controller

Automatic Transfer Switch Control Module

The Harsen TU-MM is a high-quality Automatic Transfer Switch (ATS) controller designed to manage the automatic transfer of power between two sources — such as mains and generator, mains-to-mains, or generator-to-generator systems. It ensures a smooth and reliable power transition without interruption, making it ideal for critical power applications.

Built with advanced control logic and durable electronic components, the TU-MM continuously monitors the voltage and frequency of both power sources. When the primary source fails or becomes unstable, it automatically transfers the load to the backup source and switches back once the mains supply is restored.

Key Features:

• Supports Mains-to-Generator, Mains-to-Mains, and Generator-to-Generator configurations

• Automatic and manual transfer operation modes

• Real-time monitoring of voltage and frequency for both sources

• LED indicators for system status and fault conditions

• Compact and durable panel-mounted design

• Simple installation and user-friendly operation

• Reliable performance for industrial and commercial use
