The cooperation with the German customer is a very meaningful test. The customer's demand is that their equipment is a single-phase 220v 1.1kw water pump. Due to the high inrush current in the startup process, they need a product that can reduce the impact current, reduce the impact on the power grid, and start smoothly at the same time.
It must be said that Mr Paul is very serious. He sent us the drawings for our confirmation and clearly put forward his specific needs for single-phase motor soft starter. After a lot of communication between the two sides, finally we recommend NK series built-in bypass soft starter.
Mr. Paul is a very rigorous expert. After receiving the product, he did a lot of tests on the starting current and performance of the product. The final conclusion is that our product is excellent and fully meets their requirements. Considering the multi-pump control, their subsequent orders are carried out real-time multi-machine control and monitoring through Modbus communication.
NK series built-in bypass motor soft starter performance as below:
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.
