CMV series MV solid-state Soft Starter, 3/6/10kV

Medium Voltage Soft Starter

CMV series MV solid-state Soft Starter, 3/6/10kV

CMV series soft-start device is designed to efficiently start, control, protect, and soft-stop high-voltage squirrel-cage asynchronous and synchronous motors.

It’s a new type of intelligent equipment with high performance, multi-function, and high safety.

✔ 32-bit ARM core microprocessor, optical fiber drive, multiple dynamic and static voltage equalization protection;   

✔ Reduce the starting impulse current of the motor and reduce the impact on the power grid and the motor itself;   

✔ Reduce the impact on mechanical equipment, prolong its service life, and reduce failures and downtime. 


Mains voltage: 3kV ~ 10kV

Frequency: 50/60Hz±2Hz

Communication: Modbus RTU/TCP, RS485

    • Features

    • ● Mutiple triggering methods
      The combination of single-phase optical fiber and multi-point electromagnetic triggering technology enables the safe and reliable isolation between the high-voltage thyristor trigger detection and the low-voltage control loop.
      ● Friendly human-machine interface
      Chinese/English LCD or touch screen display system, user-friendly operation interface.

      ● Different Control Methods
      Adjust according to the load characteristics to meet the requirements of on-site working conditions.

      ● Highly reliable redundant design
      In the event of a fault, the internal vacuum contactor can be utilized to directly start the motor, ensuring uninterrupted production.

      ● Strong anti-interference ability
      Strict EMC electromagnetic compatibility, high and low temperature aging experiments, standardized design and manufacturing.

      ● Patented radiator design
      Greatly improves heat dissipation efficiency, ensures the safe operation of thyristors, and extends the equipment's service life.

      ● Remote communication
      The Modbus communication function allows for remote monitoring and start-stop control. Users can view the operating status and parameters of the motor through the relevant background system.
