ABSTRACT:
A current limiting DC motor starter employing a closed loop current measurement to provide precise current control that adapts to changing motor conditions, integrated with a solid state reversing motor starter. The motor starter further includes a calibrated overcurrent indication and a control system interface that reduces the likelihood that cable faults and other single failures will cause spurious actuation of the motor.
