High performance of SSM is ensured by 32bit ARM core micro-controlling technology, high speed optical cable together with dynamic and static protecting measures. Motor torque increased to rate torque as voltage and current rises which is controlled by 32bit ARM core controller through phase shift triggering technology . SSM medium voltage soft starter decreases current flush thus impact to motor and electric network are reduced. Life time of machineries is prolonged and breakdown is lessened for reduced impact.
