NJR5-ZX series soft starter is an online soft starter, its input power voltage (main circuit voltage) is AC220V, AC380V, AC460V, AC575V and AC690V, and the rated current is from 15A to 1000A. With the characteristics of strong load adaptability, stable and reliable operation, it can be widely used in metallurgy, petroleum, fire protection, mining, water supply, municipal, food, cement, petrochemical and other scenarios. It is the most ideal replacement product for a traditional star-delta starter, auto-coupling starting.

NJR5-ZX series soft starter is an AC asynchronous motor soft starter integrating power electronics technology, microprocessor technology and modern control theory technology. By controlling the three-phase parallel thyristor connected in series between the power supply and the controlled motor, the functions of soft start and soft stop of the three-phase AC asynchronous motor can be realized. This product can effectively control the starting current and the starting torque. It can be widely used in loads such as fans, water pumps, compressors, ball mills, and crushers, etc.
