Leadshine DM870 Digital Stepper Driver 0.5-7.0A 20-80VDC for Nema 23, Nema 24, Nema 34 Stepper Motor

Leadshine DM870 Digital Stepper Driver 0.5-7.0A 20-80VDC for Nema 23, Nema 24, Nema 34 Stepper Motor

The DM870 stepper drive is designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA23, 24 and 34 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 stable performance, simple design, and easy setup features make DM870 suitable for many step & direction control type applications.
