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.
The KBCC controls are built on a rugged aluminium heatsink and contain AC line and armature fusing, a 5K ohm remote potentiometer, and a barrier terminal block. In lieu of the potentiometer, the control can be operated in a voltage following mode by supplying an isolated analogue signal (0-9VDC) to the input terminals P2 (+) and F-. Adjustment trimpots are provided for MIN, MAX, IR COMP, CL, ACCEL and DECEL.
