NJR2-D SERIES - SOFTST ARTER - User Instruction (Chint)
.png)
NJR2-D series soft starter (hereinafter referred as soft starter) is to control the conduction angle of three-phase reverse parallel thyristor connected in series between the power supply and the controlled motor , so that the terminal voltage of the motor rises from the preset value to the rated voltage, in order to achieve the purpose of reducing the current and starting smoothly during the starting process of the motor , which belongs to the category of step-down starting. Therefore, the starting torque has been reduced, which is suitable for places where the starting torque requirements are not high.
