      product description
  
 cdra-k1 soft starter is a new type of starting equipment with advanced level using power electronic technology, microprocessor technology and modern control theory technology. the product can effectively limit the starting current of asynchronous motors, can be widely used in light-load special equipment such as fans and pumps. it is an ideal replacement product for star/delta conversion, auto-coupling pressure reduction and other step-down starting equipment.the cdra-k1 soft starter can control the motor to smoothly accelerate during the starting process and smoothly decelerate during the stop process, and provides comprehensive protection functions for the motor and the product itself.
 
 
            technical characteristics
 
      1. the cdra-k1 series soft starter can directly set the start and stop parameters through 3 potentiometers;
 
      2. the cdra-k1 series soft starter have built-in bypass relays, and users do not need to add bypass contactors externally;
 
      3. the soft starter uses voltage ramp plus current limit start mode
 
      4. real-time data (a-phase current, b-phase current, c-phase current, average current, etc.), fault history records (10 fault history records, etc.), statistical data can be read through communication(accumulated starting times, accumulated running time, accumulated trip times, etc.); (optional rs-485 communication expansion card (modbus rtu protocol)
 
      5. support single-phase 220v motor (1.1-4kw); 380v motor (0.75-75kw)
 
      6. protection function of cdra-k1 series soft starter:
 
         1) overcurrent protection;
 
         2) undercurrent protection;
 
         3) overload protection (class10a, class10, class20, class30);
 
         4) the longest starting time protection;
 
         5) three-phase current unbalance protection;
 
         6) phase loss/voltage loss protection;
 
         7) phase sequence protection;
 
         8) scr (silicon controlled silicon) over temperature protection;
 
            application occasion
 
      widely used in light load special equipment such as fans and pumps
