Digita Built-in Bypass Squirrel-Cage Asynchronous Electric Motor Soft Starter
NK301 Series digital AC motor soft starter is new type starting equipment with advanced international level. This equipment designed and manufactured by the technique of power electronics microprocessor and modern control theory. This equipment can limit the start current efficiently when the asynchronous motor starts. It is widely applied in the field such as winding machine, pump, transition and compressor etc. It is the ideal product to replace the traditional voltage dropping start equipment such as star/triangle conversion, self-coupling voltage dropping, magnetic control dropping voltage etc.
Features
1. Based on the load characteristics, different starting mode can the related parameters can be selected. So the best starting effect can be gained.
2. The higher performance microprocessor and software are used, so the control circuit is simplified. The best perform speed can gained without the adjustment of the circuit parameters.
3. All the electronic components of this product are selected strictly. Additionally, the main control board is tested in high temperature environment above seventy-two hours. The reliability of this product can be guaranteed.
4. The modularization configuration and up-in-down-out wiring mode are adopted. It is easy to used and integrated.
5. The motor protection circuit is not be added if the single product is in used. Because this product have multiple protection function such as Overload; Line fault; Over current; the starting time and so on. So the cost can be reduced and the circuit can be simplified.
6. Operation of the keyboard is easy. User can set and modify the parameters (for example, starting, stopping running protection) by this keyboard based on the different load condition.
7. 4-20mA output analog signal is provided.
8. RS485 Modbus Communication Protocol；
9. When the rate power of Soft Starter is higher than the power of actual load, soft starter can be matched to the actual load by modifying the actual current parameter. So the parameters about starting,running and protection are correct
