Special control circuit,greatly reduce noise,increase steadiness;

Upmost response frequence amounts to 50Kpps;

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

Bipolar constant current chopper control;

Photocoupler isolated input/output ;

Drive current range from 0.5A/phase~4.0A/phase;

Single power input, voltage range from DC12-40V

Overheat protection&Overcurrent,under voltage protection.
