Product Summary

The soft starter, namely SMC intelligent soft starter(non-contact solid state controllor), is a new motor starting product, substituting for the old traditional starter such as star-delta starting, autotransformer, field-control starter,etc. It has been widely used in industry field.

The intelligent soft starter is the new products integrating with microprocessor and high-power thyristor technology.The microprocessor control the conduction angle, changing the output voltage of the thyristor and making the motor’s start and stop rotating speed meet the requirement of pump’s.The soft start and stop plays an important role in prolonging the device’s service life and preventing from the water hammer impact.


  1. Lower motor starting current and reduce the capacity of distribution.
  2. Decrease the starting stress and prolong the motor and the other device’s service life.
  3. Steadily soft start and soft stop, avoiding surge problem of traditional device starting and water hammer impact.
  4. With various starting models and wide setting range of voltage and current, it can suitable for many load conditions
  5. It is an ideal equipment of protecting the motor and related devices.
  6. It is designed for frequently starting and stopping.
