Motor starter RDJR6 series soft-starter Application AC induction-motor has advantages of low-cost,high reliablity and infrequent maintainance. Disadvantages: 1.starting current is 5-7 times higher than rated current.And it requires that power prid has large margin,and it also would reduce the working life of electrical control device,improving maintainance cost. 2.starting torque is doule-time of normal starting torque to cause the load shock and drive components damage. The RDJR6 soft-starter adopts the controllable thyistor module and phase shift technology to improve the voltage of motor regularly.And it can realize the requirement of motor torque,current and load by control parameter. RDJR6 series soft-starter adopts microprocessor to control and realize functions of soft-starting and soft-stopping of AC asynchronous motor,has complete protection function,and widely used in Motor drive equipment in the fields of metallurgy,petroleum,mine,chemical industry. Non:for install type, G for cabinet type Rated power(applicative power:kW) Design code Soft-starter AC motor Company code production feature Adopts the Microprocessor digital auto control,it has great electromagnetic performance. soft starting,soft stoping or free stoping.The starting voltage,current,soft-start and soft-stop time can be adopted according to different loads for reducing the shock of starting current. stable performance,easy operation,direct display,small volume,digital set,has telecontrol and external control functions. has protection against phase-loss,overvoltage,overload,overcurrent,overheating. has functions of input voltage display,operating current display,failure self-inspection,fault memory. has 0-20mA simulation value output,can realize motor current monitoring.
