2, Stepper Motor Driver with 4.2A Current, 128 Microstep

DQ542MA is a type of two-phase hybrid stepping motor driver, The drive voltage of which 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 that it adopts is similar to the circuit of servo control which enables the motor run smoothly almost without noise and vibration. Hording torque when DQ542MA run under high speed is also significantly higher than the other two-phase driver, what's more, the positioning accuracy is also higher. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, Computer embroider machine, packing machines and so on.


l High performance, low price

l Average current control, 2-phase sinusoidal output current drive

l Supply voltage from 18VDC to 50VDC

l Opto-isolated signal I/O

l Overvoltage, under voltage, overcorrect, phase short circuit protection
