stepper motor driver

Stepper motor driver,High performance, low price RB2303 is a microstep driver, voltage range from DC12-30V, single power input. It can match 4leads\ 6 leads or 8 leads two phase hybrid step motors whose rated current under 2.0A flange size range from 28mm-42mm. 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. Two group 8 channels constant angel and constant torque subdivision. Highest subdivision:128 Special control circuit to reduce the noise Upmost response frequency amounts to 800kpps Once the pulse stops for 300ms, phase current automatically cut by half Bipolar constant current chopper control Photocoupler isolated input/output Drive current from 0.1A/phase to 2.0A/phase Single power input, voltage range from DC12-30V Overheat prortection, Overcurrent &TSD protection; Once the temperature over 170°C, the protection will turn on Dimension 85mm×58mm×27mm;Net weight:0.160k g
