Three phase stepper motor driver MD3778

The MD-3778 three-phase stepper motor driver is a cost-effective segmented driver based on the 16 bit DSC platform, with superior performance, high-speed high torque output, low noise, low vibration, and low heat generation, especially suitable for OEM customers' large-scale applications. The MD-3778 driver can select operating current and subdivision through a dip switch, with 8 types of subdivision and 8 types of current to choose from. It has overvoltage, undervoltage, phase current, and bus overcurrent protection, and its input and output control signals are all optically isolated. Power supply: MD-3778: 24 to 75 VDC; L Output current: dip switch selection, 8 options, MD-3778: maximum 7.8 amperes (peak) l Current control: PWM chopper control, high-speed high torque output, low vibration, low noise, low heating l Subdivision settings: dip switch setting, 8 options: 1000, 1600, 2000, 3200, 4000, 5000, 6400, 51200 step/rev
