Features
■Reducing the motor starting current.
■ It avoids the instantaneous dropping the voltage of power line and the error operation of installation , when the motor is sarted.
■ It porestalls porducting the torque shocek and breaking the mechanical shaft making the equipment trouble, when the motor is started.
■ It can frequently start motor(The soft starting equipiment generally pemits 10 starting in hour and the motor can not be ovent heated).
■ It avoids the water hammer effect for pump load, so it can forestalls breaking the tubes.
■ For the some technology application(such as coloring yam machine).it can forestall the unegual dyeing quality owing to the starting motor.
■For the some easy smashed contain irrigating thick liquid production line, it can forsetall breaking the contain.
■ According to the requirement, the starting current can be controlled to reduce the mechanical shock. At same time , it suitable for low power capacity transformet.
■It is suitable for the smoothe torque load and can reduce the appropriate power line capacity to save the expense for increasing the power capacity.
