A 5k ohm speed potentiometer is included.
Standard features include: armature or tach feed back, and trimpots for MIN, MAX, IR Comp, CL and Linear ACCEL and DECEL. An exclusive feature, found only in KB drives, is Auto Inhibit®, which provides a smooth, safe start during rapid switching of the AC line. The unit contains a 42 Amp power bridge and armature and control fusing, which enhance reliability. It is built on a rugged aluminum chassis and uses the KBMM™ speed control, which contains Direct-Fed™ CL circuitry, for excellent performance and reliability. The KBCC-255 is designed for 5 HP DC Shunt and PM motors. Patented.-Reverse, Run-Stop and Forward-Reverse (instant reverse).
This control provides functions identical to that of the KBCC™-R. The KBPB™ is equipped with a built-in dynamic brake resistor, Accel/Decel trimpots and provision for AC line and armature fusing. A built-in Barrier Terminal Block and its small size make the control ideal for installation where space is at a premium. The APRM® is mounted directly to the rear of the KBMM™ speed control. The KBPB™ is a compact version of the KBCC™ “R”-suffix control. Specific functions that can be performed by the KBCC™-R are Run-Brake, Forward-Brake-Reverse, Run-Stop and Forward-Reverse (instant reverse). The APRM® eliminates contact arcing by allowing armature switching to take place only when current levels are near zero.
It com-bines all of the features of the KBCC™ control with the features of the KB APRM®. The KBCC™ “R” –suffix chassis control is designed to provide anti-plug “instant” reversing, solid state dynamic braking and rapid cycling. The controls are ruggedly constructed and contain a 5k ohm speed potentiometer.

They include all the features of the KBMM™ plus the Auxiliary Heat Sink and Barrier Terminal Block with AC line and armature fuses. The KBCC™ chassis controls utilize the KBMM™ speed control to provide a low- cost, reliable SCR drive. Options: Auxiliary Heat sink, Barrier Terminal Options, and SI-6 Signal Isolator. Auto Inhibit, MOV transient protection, 5k ohm potentiometer and Noise Rejection Circuitry. Standard features include trimpots for MIN, MAX, IR, CL and Linear ACCEL and DECEL, armature or tach feedback. KB's exclusive Plug-in Horse power Resistor® eliminates the need for recalibration when used over a wide range of motor horse power.
25A SCR's and AC line and armature fusing further enhance reliability. Contains Direct-Fed current limit that helps protect the SCR power bridge against direct shorts and prevents demagnetization of PM motors. The KBMM™ full-wave DC motor control is the ultimate in reliability and performance. Note: Output rating of model KBIC-240DS is 90 VDC Only. Options include Auxiliary Heat Signal Isolator. Features include Auto Inhibit®, Voltage following, MOV transient protection, 5k ohm speed potentiometer and trimpot adjustments for MIN, MAX, ACCEL, IR and CL. Speed range is 50:1 with load regulation of 1%. All models can be used on a wide range of motor horsepower by inserting KB's exclusive Plug-In Horse power Resistor®. The KBIC® controls PM, Shunt and AC/DC motors over a range of 1/100-3 HP with only a few models. KB Variable Speed DC Drives (SCR, PWM, Regen) “ KB’s broad range of analog style Penta Power VFDs and our new line of Genesis Digital Drives can provide you with off-the-shelf solutions for almost any application.’’
