* 20KHz chopping frequency.Low speed without vibration. Low noise. In the harsh environment of the power grid, it had strong
anti-interference ability, high-precision positioning and high reliability.
* Suit for Nema 17, 23 Stepper Motor，2-phase hybrid stepper motors (Outer diameter: 57,86mm)
* Output current DIP switch is adjustable.Optical isolation signal input, strong anti-interference ability with over voltage,
over light and other protective functions
* H bridge bipolar constant phase flow subdivision driver.Precision electric casting control greatly reduces motor heating and
halve the chattering automatically at rest
* High segmentation: 2,4,8,16,32,64,128,256. 5,10,25,50,125,200
