Digital Stepper Driver 2.1-8.4A 24-70VAC or 30-110VDC for Nema 34 Motor

The DM860S is a two phase digital stepper driver based on 32-bit DSP technology. The microstep resolution and output current can be set by users. It has advanced control algorithm which brings a unique level of system smoothness, provides optimum torque and mid-range instability. Compared with traditional analog drives, DM860S can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM860S an ideal choice for high requirement applications. It is highly recommended to work as nema 17 and nema 23 driver.
