Standard Features
Plug-In Horsepower Resistor®: Automatically calibrates the IR Compensation
and Current Limit settings when used on various horsepower motors. Supplied
separately by your distributor.
Short Circuit Protection: Prevents drive failure if a short circuit occurs
at the motor.
Undervoltage Protection: Shuts down the drive if the input voltage goes below
the lower limit of the operating range. The drive will resume operation when the
input voltage returns.
Quick-Connect Terminals: Battery, Motor, and Inhibit.
Inhibit Circuit: Can be used to stop and start the drive electronically with
a switch or contact.*
Signal Inputs: 5 kΩ potentiometer (supplied), 0-5 Volt DC analog signal,
or PWM microprocessor output signal.

Optional Accessory
Auxiliary Heat Sink Kit (Part No. 9142): Increases the drive’s current rating
from 14 Amps DC to 20 Amps DC.
Description
The KBBW Series of Pulse Width Modulated (PWM) DC/DC
motor speed controls provide excellent dynamic response to load
variations. The efficient PWM waveform produces an almost pure DC
current to the motor (form factor <1.05), which provides low audible
motor noise and long brush life. Pulse-by-pulse current limit provides
short circuit protection and prevents control damage due to shorted
motors. Excellent load regulation is achieved with armature feedback.
The Plug-In Horsepower Resistor® (supplied separately)
eliminates the need for recalibrating the IR Compensation and
Current Limit settings when the control is used on various
horsepower motors. Quick-connect terminals are standard for all
connections to the drive. Adjustable trimpots allow the drive to be
tailored to specific applications. The Inhibit Circuit can be used to
stop and start the drive electronically with a switch or contact.
The 5 kΩ potentiometer (supplied), a 0-5 Volt DC analog signal,
or a PWM microprocessor output signal can be used to control motor
speed. The optional Auxiliary Heat Sink Kit (Part No. 9142) increases
the drive’s current rating from 14 Amps DC to 20 Amps DC.
