Stepper Motor Driver 18V-50V 2Phase 4A

Two-phase hybrid stepping motor driver, the drive voltage is from 18VDC to 50VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter and less than 4.0A phase current. This circuit enables the motor to run smoothly almost without noise and vibration. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machines and so on.

For 12V I/O use 1K series resistor on + lines. For 24V I/O use 2.2K series resistor on + lines.
