The Haydon DCS4020 Chopper Drive delivers optimum performance
throughout a greater speed range. This new technology drive has been designed
for easy set up and use. The Haydon DCS4020 is ideal for development projects
where a single power supply is all that is necessary to easily run the motor.
The motor current is set using an on-board potentiometer and no external current
setting resistors are required.

The Haydon DCS4020 is also feature-packed. The Driver provides all the basic motor controls including full or half-stepping of bipolar steppers, directional control, and output
enable control. An oscillator circuit is standard on the drive with its onboard
potentiometer. In addition, external input/output signals allow complete remote control of all drive functions. All electrical connectors have removable plugs incorporating screw type terminals.
