We are offering soft starter. applications motor drive, especially for larger kw. 1. adopt 16 single chip micyoco digital automation automation control 2. the mode of connection is three input and six output, all series on line protaction will come ture. 3. the main component is from japan and the brand of cpu is philip. 4. based on the different load we can set different current and voltage time of start torque , then we can get the best current pulse and the characteristic of the torque. 5. it can provide motor slip start progress, reduce the starting current on the impact of power grid. Reducing vibration and noise of equipment . Extended the life span of mechanical transmission, and improved working environment for artificial. 6. starting current can be adjusted based on different load. Reduce the loss of start and to get the best torque based on the smallest current. 7. has different kinds of protection, such as over current , over load and lin input phase loss, to insure the safety of the equipment and motor. 8. they’doutput of the soft-start will be increased based on the setting the law, so controlled in accordance with the superior optimization of motor speed up the curve to complete the boot process. 9. a convenient external control interface has multi-function: digital delay start control, soft stop control input, start delay relay output, fault relay output. 10. automatic identification of phase sequence and phase sequence protection with themselves 11. . Are free to stop and soft-stop adjustable soft stop time 12. all-digital set and external control functions greatly facilitate the user. 13. standard rs232/rs485 communication (reserved) 14. product novel structural properties of small size and easy to use and reliable operation of the installation.
