stepper motor driver

RB2403 is a microstep driver, voltage range from DC12-40V, single power input. It can match 4leads/6 leads or 8 leads two phase hybrid step motors whose rated current under 3.0A flange size range from 42-57mm. Owe to bipolar constant current chopping circuit, the motor can run smoothly and hardly has any noise.Rising the voltage can greatly improve high speed performance and output torque of the motor. Once the pulse stops for 300ms,the phase current will automatically cut by half, which can reduce chances of overheat.
