The KBIC® controls PM, Shunt and AC/DC motors over a range of 1/100– 3 HP with only a few models. All models can be used on a wide range of motor horsepower by inserting KB’s exclusive Plug-In Horsepower Resistor®. Speed range is 50:1 with load regulation of 1%. Features include Auto Inhibit®, Voltage Following, MOV transient protection, 5k ohm speed potentiometer and trimpot adjustments for MIN, MAX, ACCEL, IR and CL. Options include Auxiliary Heat Sink, AC Line and Armature Fuse Kit, Barrier Terminal Options and SI-5 Signal Isolator.


The KBWM control is a compact version of the Multi Drive™ (KBMD). The control is packaged in an all-metal NEMA-1 enclosure. This unidirectional SCR drive utilizes the KBMM speed control module, which prevents motor failure due to demagnetization, and contains AC line and armature fusing and a barrier terminal connection block. The KB Plug-In Horsepower Resistor® automatically calibrates IR Comp and CL.


The Model KBMD-240D, also called Multi-Drive™, is a packaged SCR drive in a NEMA-1 enclosure. It utilizes the KBMM™ speed control for its electronics. The Multi-Drive™ is rugged and compact in size. It handles both 115 and 208/230 Volts AC line inputs by setting the built-in Dual Voltage Switch. In addition, the single model can be used on a wide range of motor horsepower by inserting the appropriate Plug-In Horsepower Resistor®. The Auxiliary Heat Sink P/N 9861 (optional) increases the rating of the basic unit to 1 HP at 90 VDC and 2 HP at 180 VDC. An optional Forward-Brake-Reverse Switch Kit (P/N 9860) is also available.


The KBPC Series NEMA-4X (IP-65) SCR DC Motor Speed and Torque Control is designed for applications requiring washdown and watertight integrity. Its housing is ruggedly constructed of die cast aluminum which is protected with an acrylic coating. Exclusive Short Circuit and Timed
Current Limit (TCL) circuitry prevents motor burnout and demagnetization of PM motors. Features such as Selectable Current Range eliminate unnecessary calibration of IR and current limit trimpots. Other selectable features are: Input voltage (115, 208/230 Volts AC), Output Voltage (90, 180 Volts DC), Current Range (2.5, 5, 7.5, 10) amps, Input Signal (0-5, 0-
20) Volts DC, Armature or tach feedback, Tach voltages (7, 20, 30, 50 Volts/1000 RPM). Trimpot Adjustments include: MIN, MAX, ACCEL, DECEL, IR, CL and TCL. Standard features include: Armature Fusing, Electronic Start-Stop and diagnostic LED Indicator Array for “Power On,” “Stop” and “Overload.” The KBPC-225 contains all of the features of the KBPC-240D
except Armature Fusing. In addition, it is designed specifically for 3HP - 180 VDC PM or shunt motors operating from a 230VAC line. Accessories include: KBSI-240D Signal Isolator, Electronic Fwd-Brk-Rev containing APRM-PC, hesitation type Fwd-Brk-Rev switch kit and switches for AC Line ON/OFF, Run-Stop-Jog and Auto/Manual.
