SCR drives are the workhorse of the variable speed DC motor industry. This technology continues to dominate not only the installed base but new sales every year, and will continue to do so well into the future.
Dart SCR drives convert single-phase line voltage (120/240V AC) into full-wave rectified DC for use with both DC permanent magnet and shunt or field-wound DC motors. SCR drives control the motor speed by adjusting the voltage output to the drive. Current (amp) draw is determined by the motor and its load—drives with the Current Limit feature will protect both the motor and control from damage.
