NK series soft starter is a full digital product. Suitable for squirrel-cage asynchronous motors: Rated voltage: **0V***0V Rated power: 0.****5KW. The NK series soft starter can control the motor to accelerate smoothly during the starting process and decelerate smoothly in the process of stopping. It also provides a comprehensive protection function for motors and itself.

Features:

1. Start/stop slope and initial voltage set by 3 different potentiometers built-in 
2. Bypass relay built-in, No need for extra contactor 
3. Voltage slope startup mode 
4. The output torque can be maintained during the stop process(Continuous torque control), prevent water hammer effect 
5. External△，Y or Internal△ Wiring mode 
6. Real-time data of communication(A,B,C phase current, average current) *1 
7. Reading history fault records by communication ( *0 history log)*1 
8. The statistics data can be read by modbus communication.*1 

Protections: 

  1) 8xIn overcurrent protection. 
  2）5~8.5xIn Continued Over current Protection. 
  3) Over load Protection with classes *0A, *0, *0 and *0. 
  4) Three phase current imbalance Protection. 
  5) No voltage protection. 
  6) Phase Missing Protection. 
  7) Phase Sequence Protection. 
  8) SCR Overheating Protection.
