Leadshine Digital Stepper Driver 0.5-4.2A 20-50VDC for Nema 17, 23, 24 Stepper Motor

The DM542 stepper drive is designed to power 2 phase(1.8°) or 4-phase(0.9°) NEMA17, 23 and 24 hybrid stepper motors. It can be adopted in many industries(CNC machinery, electronics, medical, automation, packaging…) for applications such as CNC routers, mills, plasma, laser cutters, factory assembly lines, vending machines, etc. Its excellent performance, simple design, and easy setup features make DM542 ideal for many step & direction control type applications.
