MT830 high voltage solid state combined integrated soft starter

The MT820 series high-voltage solid-state soft starter is professionally designed using high-performance thyristors and modern power electronic control technology. This advanced system provides smooth motor soft start and stop capabilities, energy saving features, and comprehensive protection functions for constant speed AC motors.

With its small starting current and smooth operation, this soft starter extends the service life of motors and equipment. It is ideal for various applications including centrifuges, fans, pumps, conveyor belts, and drag systems.
