Abstract
An induction motor controller with a scaling convertor for both providing selective alteration of the overload sensitivity characteristic of the controller and converting the input current to a proportional control voltage. The feedback circuit includes a plurality of feedback resistors which are selectively connectable between the output of the current-to-voltage convertor and its input to selectively change its gain and thus the sensitivity of the controller.
