Medium voltage soft starter
Medium voltage soft starter has complete comprehensive protection function for the motor running, which can ensure that electrical and mechanical rotating equipment operates safely and reliably at various circumstances. Compared with other types of high voltage motor soft starter (such as liquid resistance type), soft starter costs less energy in the process of starting. Therefore it has obvious energy saving effect, and can be started frequently. At the same time, since soft starter is a solid state device, it can work for a long-term without maintenance, small in size, easy to move, having good vibration resistance and other significant advantages. It is the ideal replacement for other traditional medium-voltage soft start products.

Medium-voltage soft starter is mainly composed of medium- voltage silicon controlled
(thyristor) components, medium- voltage vacuum contactor, signal sampling circuit, trigger
circuit, power driver circuit, main control board, optical fiber isolation signal cables,
secondary relay control circuit, high voltage cabinet and other parts.
How does it work?
- The initial voltage of starting can be set flexibly according to the actual situation and demand of the equipment.
- The lowest set point is 15% of the supply voltage,The highest is 90%.
- Thus the motor has a larger starting torque and smaller starting current which reduces the equipment of power grid capacity required by equipment operation and saves the investment of related equipment.
- It reduce the impact stress to motor itself and to the machinery which can prolong the device life of motor and the machinery.
-PLC control, HMI display

We have three types for Medium voltage soft starter, The standard , the new and the custom model. You carefully find that two kinds of voltage and power conversion is realized. That means, you will have your own idea on the products, as per the actual demand. Just everything to us.
