Product Desciption
Product Features
© Reduce the starting current, reduce power supply peak current, reduce the cost of distribution equipment. Reduce the abrasion of motor, improve the service life of mechanical equipment.
© Optional starting parameters are convenient in one soft starter starting different motors.
© Soft starter inspects motor feedback voltage to realize closed loop control, ensure the motor start-up success in different conditions and different loads.
© A variety of starting ways: voltage ramp starting way can get the maximum output torque; Current limiting can realize biggest limitations of the soft start starting current.
© Reliable quality assurance: using computer simulation design; SMT production process; Excellent electromagnetic compatibility performance;High tSTperature aging, vibration test of the machine before delivery.
© Perfect and reliable protection function: loss of voltage, less voltage, over voltage protection; overheating, starting time too long; Input phase lost, output phase lost, three-phase imbalance; starting over current, overload and load short circuit protection, etc.
© Full dynamic control field-bus monitoring starter, easy networking
© LCD displaying screen can display parameter code, state and error.

- The rated power and rated current indicate the maximum rated value of the soft start. The matching specification of breakers and bypass contactors should match with the motor.
- Soft starter is for six terminal inputs and three terminal outputs, it is still with the online protection function at the state of bypass contactor sucking, do not need to add additional motor protection device.
