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

Model Specifications

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.
