Leadshine DMA860H 2 Phase Stepper Driver 18-80VAC for Nema23 Nema34 Nema42 Stepper Motor

Leadshine DMA860H 2 Phase Stepper Driver 18-80VAC for Nema23 Nema34 Nema42 Stepper Motor

The DMA860H is a digital stepper drive with simple design and easy setup. By implementing Leadshine advanced stepper control technology, this stepper drive is able to power 2-phase and 4 phase stepper motors smoothly with optimal torque and low motor heating & noise. Its operating voltage is 18-80VAC or 24-110VDC and it can output up to 7.2A current. All the micro step and output current are done via DIP switches. Therefore, the DMA860H are suitable for applications requiring simple step & direction control of NEMA 23, 24, 34, and 42 stepper motors.
