NK series soft starter is a full digital product. Suitable for squirrel-cage asynchronous motors: Rated voltage: 200V-500V Rated power: 0.75-75KW. 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 ( 10 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 10A, 10, 20 and 30.
4) Three phase current imbalance Protection.
5) No voltage protection.
6) Phase Missing Protection.
7) Phase Sequence Protection.
8) SCR Overheating Protection.
