/VIh/fl Drives Chassis The KBTC controls are designed to control a motor’s torque by controlling motor current. Unlike a traditional KBIC, which controls voltage and limits current, the main potentiometer of the KBTC sets current. The KBTC connections are the same as a KBIC control and can use the same accessories, such as the Barrier Terminal Board and Barrier Terminal Kit. The SI-5 signal isolator can also be used to allow a remote voltage or milliamp current signal to set motor torque. The control includes a fixed value of a Plug-in Horsepower Resistor (0.015 ohm) for all motor sizes. SI-5...

The KBIC Series of DC Drives includes six models rated for 1/100 to 3 horsepower motors. All models can be operated on a wide range of motor horsepower by inserting a Plug-In Horsepower Resistor®, which is required to operate the drive. Speed range is 50:1 with load regulation of 1% of base speed. These chassis drives include MOV transient protection, trimpot adjustments for MIN, MAX, ACCEL, IR, CL, and a 5k ohm potentiometer. This drive also contains Auto Inhibit® which provides a smooth, safe start during rapid switching of the AC line. • SI-5 Signal Isolator (Item Number 9443) • Barrier Terminal...

/VIh/fl Drives The KBMM Series of DC Drives includes three models rated for 1/100 to 3 horsepower motors. This chassis full-wave DC motor control is the ultimate in reliability and performance. The drive contains Direct-Fed™ CL that helps protect the SCR power bridge against shorts due to commutator arcing and prevents motor demagnetization. 25 Amp SCRs and AC line and armature fusing further enhance reliability. A Plug-in Horsepower Resistor® is required to operate the drive and eliminates the need for recalibration when used over a wide range of motor horsepower. They include an AC line fuse...

The KBMG Series of DC Drives includes two models rated for 1/100 to 2 horsepower motors. This chassis ultra-compact, full-wave regenerative drive is capable of operating DC PM or Shunt motors in a bidirectional mode. Its 4-quadrant operation provides forward and reverse torque in both speed directions. Included is jumper selectable Input AC Line Voltage, Armature Current, Motor Armature Voltage, Analog Input Voltage, Control Mode (Speed or Torque) and Coast to Stop (CTS) or Regenerate to Stop (RTS). The Overspeed Protect Circuit prevents failure of the power bridge in extreme overhauling conditions....

The KBRG Series of DC Drives includes three models rated for 1/8 to 5 horsepower DC Permanent Magnet and Shunt motors. These are full-wave regenerative controls, which allow forward and reverse torque in both speed directions. Features include armature and tachometer feedback, built-in horsepower selection, an AC Line fuse and an armature fuse. Trimpots adjustments for Fwd CL, Rev CL, IR Comp, Resp, Max Spd, Offset, Deadband, Fwd Accel, Rev Accel, Timed Current Limit (TCL), and two torque modes. LED indicators for power on, current limit, Fwd Enable, and Rev Enable. This drive also contains Auto...

/VIh/fl Drives The KBWM Series of DC Drives, housed in a NEMA 1 enclosure, includes two models rated for 1/100 to 3/4 horsepower motors. These drives are the compact version of the Multi Drive™ (KBMD). This unidirectional SCR drive utilizes the KBMM speed control module, which prevents motor failure due to demagnetization. It requires a Plug-in Horsepower Resistor® to operate and includes an AC line fuse and armature fuse holder. This drive also contains Auto Inhibit® which provides a smooth, safe start during rapid switching of the AC line and a terminal block to facilitate wiring. • KBSI-240D...

The KBPC Series of DC Drives includes four models and are rated from 1/100 to 3 horsepower motors. These drives are housed in a NEMA 4X / IP 65 die-cast aluminum washdown/watertight enclosure for indoor or outdoor use. The exclusive Short Circuit and Timed Current Limit (TCL) circuitry prevents motor burnout and demagnetization of PM motors. Features, such as a selectable motor current, eliminate unnecessary calibration of the IR and CL trimpots. Other selectable features are Input Voltage, Output Voltage, Current Range, Input Signal, Armature or Tachometer Feedback, and Tachometer Voltage. Trimpot...

The KBRC-240D DC Drive is a Full-Wave Regenerative Drive housed in a NEMA 4X / IP 65 washdown/watertight enclosure for indoor or outdoor use. The KBRC-240D is designed to operate Permanent Magnet and Shunt Wound DC motors from 1/100 to 2 horsepower, in a bidirectional mode. It has 4-quadrant operation, which provides forward and reverse torque in both speed directions. An important feature, Timed Current Limit (TCL), provides motor burnout protection. The KBRC-240D can be operated from a two or three wire start/stop circuit or can be started from the AC line. A set of dedicated normally open...

Accessories SI-5 & SI-6 Signal Isolators Item Numbers 9443, 9444 The Signal Isolators convert a standard control to an isolated input. By using external resistors, the input signal can be changed to 0-100VDC, 0-200VDC and 4-20mA. The output voltage is 0-10VDC which can be rescaled with the built-in MIN and MAX trimpots. Selectable AC line jumpers allow the SI-5 and SI-6 to be used either with 115 or 208/230 Volts AC controls. Installation is made by simply mating the unit to the speed control with the built-in quick-connect terminals. For use with Drive Model: KBIC and KBTC, SI-5 (9443) and KBMM,...

Barrier Terminal Kits Item Numbers 9863, 9883 The Barrier Terminal Accessory Kit converts a standard KBIC® or KBMM from 1/4” Q-D terminals to barrier terminals. It installs easily with its preformed wiring harness and is compatible with KB’s 7” Auxiliary Heat Sink. The Kit contains AC line and Armature fuse holders (fuses supplied separately).
