DC/DC Motor Speed Controls feature low voltage operation.
Press Release Summary:
Operating on 12 Vdc and 24 Vdc, respectively, battery-powered Models KBBW-12 and KBBW-22 provide optimal dynamic response to load variations. Motor speed can be controlled by 5 kΩ potentiometer, 0–5 Vdc analog signal, or PWM microprocessor output signal. PWM waveform produces almost pure DC current to motor which provides low audible motor noise and extended brush life. Providing short circuit protection, pulse-by-pulse current limit prevents control damage due to shorted motors.
Original Press Release:
KB Electronics, Inc. Introduces a New Battery Powered DC/DC Low Voltage Motor Speed Control: KBBW Series
Coral Springs, FL -- KB Electronics, Inc. of Coral Springs, FL, a manufacturer of AC and DC drives from fractional through 5 horsepower, introduces two battery powered DC/DC low voltage motor speed control models. 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 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. Model KBBW-12 operates on 12 VDC and model KBBW-22 operates on 24 VDC.
“We are pleased to continually deliver quality drives to our customers" reports Vice President of Sales, Alan Bueller. “The new KBBW drives expand our DC product line to now include a low voltage speed control.”
The Plug-In Horsepower Resistor® (PHR) (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.
