Overview

The EDE12400 stepper motor control module offers designers a compact, reliable stepper motor control system. Engineered with internal and external heatsinks and a highly thermally conductive potting compound, the need for cooling fans (known for short lifetimes) or a large heatsink plate is eliminated. An integrated chopper drive circuit safely provides the maximum motor torque for a given drive voltage, even one many times over the manufacture-specified voltage, offering tremendous torque and speed improvements over traditional stepper motor control circuits. Maximum coil current is easily set using a potentiometer or voltage divider, and can be dynamically adjusted. The highly efficient design of the EDE12400 drive circuitry combined with its unique PowerCube? package makes it the ideal motor control solution for nearly any application.
