The KBCC chassis control utilizes the KBMM™ 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 Inhibit™ which allows for electronic switching of the armature voltage and Auto Inhibit® which provides rapid safe switching of the AC line.
