Junqi M545D 2-Phase Stepper Driver For Current Less than4.5A Nema23,Nema34 Stepping Motor
Product Descriptions:
The M545D is a new generation microstep stepper motor driver. Due to the adoption of the advanced bipolar constant-current chopper driver technology, it shows stable operation, provides excellent high torque. Moreover, it significantly reduces the noises and vibration of the operating motor. The M545D has the feature of low-noise, low-vibration and low-heating. The M545D is DC24-48V power supply. It applies to 2-phase hybrid stepper motor under 4.5A current The M545D has 14l kinds of microsteps. The maximum step number is 51200 steps/rev (microstep is 1/256). The peak operating current ranges from 1.5A to 4.5A., and the output current has 8 stalls. The M545D has automatic semi-flow, motor misconnected,over-voltage, under-voltage, and over-current protection functions.
