The KBCC chassis control utilizes the KBMMTM modular control to provide a low-cost, reliable, variable speed SCR drive for PM and Shunt Wound DC motors. Models with the “R” suffix contain the KB APRM®* which provides anti-plug “instant” reverse and solid state dynamic braking. All models are equipped with KB’s exclusive Plug-in Horsepower Resistor®. It eliminates the need for recalibrating IR Comp and Current Limit when the control is used on various horsepower motors. The controls also contain InhibitTM which allows for electronic switching of the armature voltage and Auto Inhibit® which provides rapid safe switching of the AC line.
