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 k Ohm 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.
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 k Ohm Potentiometer (supplied), 0-5 Volt DC analog signal, or PWM microprocessor output signal.
