Low noise and runs smoothly;

Provides 12/8 kinds microstep selection,upmost microstep can be set to 200x.

Special control circuit,greatly reduce noise,increase steadiness.

Upmost response frequence amounts to 200Kpps.

Once the pulse stops for 100ms,phase current automatically cut by half.

can match two phase hybrid step motors whose rated current under 4.0A.

Photo coupler isolated input/output

Drive current range from 0.1A/phase-4.0A/phase

Single power input, voltage range from DC12-40V;

Overheat protection&Overcurrent, under voltage protection;
