Digital Stepper Driver 1.0-4.2A 24-48VDC for Nema 17, 23, 24 Stepper Motor

The DM542S is a two phase digital stepper driver based on ARM. Its microstep resolution and output current are programmable. And 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, DM542S can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM542S an ideal choice for high requirement applications. It is highly recommended to work as nema 17 and nema 23 driver.
