KB Electronics, Inc. introduces the newest members of its KBAC Hybrid Drive™ family.

KB Electronics, Inc. Manufacturer of Variable Speed AC and DC Motor Controls


KB Electronics, Inc. of Coral Springs, Florida, a manufacturer of AC and DC Drives, is proud to introduce the newest members of its popular line of Hybrid Drives: Models KBAC-217 (5 HP) and KBAC-416 (10 HP).

Hybrid Technology- By definition, a hybrid is the merging of two technologies. These drives combine the digital technology of the microprocessor with an easy to use analog interface. Simple trimpot adjustments and selectable jumpers are used instead of complicated programming. You will be up and running in less than 10 minutes.

Applications –These new inverter products meet a broad spectrum of customer requirements. Conveyor systems, food and beverage systems, industrial fans and pumps will utilize the KBAC technology. The simple and robust design can be specified in retail, factory floor or harsh outdoor environments.

Safe and Secure- Built with all environmental concerns and the latest product safety in mind, these NEMA 4X / IP65 drives are housed in our newly designed heavy-duty die-cast aluminum package “C” enclosures. In addition, S-suffix models (e.g. KBAC-217S) contain a state of the art mechanical interlock on/off switch equipped with a safety lockout feature that can be used with a padlock, which prevents the drive from being turned on while the related equipment is being serviced.

An AC Line filter, which is available for all models, provides Class “A” RFI (EMI) suppression and complies with CE Council Directive 89/336/EEC Industrial Standard.  Add suffix “F” to any drive model.

“We are pleased to expand our product line of motor controls up to 10 HP” says Thomas Dalton, VP GM, KB Electronics, Inc. “This new model series of KBAC drives, in addition to a full line of accessories, will meet demanding customer requirements and be a great addition to our product line.”

About KB Electronics, Inc. - Since 1967, KB Electronics, Inc. has dedicated itself to manufacturing the best AC drives and DC drives. KB designs and builds, in the United States, over 200 motor speed control models to serve the fractional to 10 horsepower market.

New Battery Powered DC/DC Motor Speed Control

KB Electronics, Inc. Manufacturer of Variable Speed AC and DC Motor Controls

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 controlmodels. 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.
