EM12-G3/P3 models are integrated IGBT.
1. Reduce the starting current, reduce power supply peak current, reduce the cost of distribution equipment. Reduce the abrasionmotor, improve the service life of mechanical equipment.
2. Optional starting parameters are convenient in one soft starter starting different motors.
3. Soft starter inspects motor feedback voltage to realize closed loop control, ensure the motor start-up success in different conditions and different loads.
4. 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.
5. Reliable quality assurance: using computer simulation design; SMT production process; Excellent electromagnetic compatibility performance, High temperature aging, vibration test of the machine before delivery.
