Product Announcement from KB Electronics, Inc.
The KBVF Adjustable Frequency Drive is designed to provide variable speed control of standard three-phase AC induction motors. Adjustable linear acceleration and deceleration are provided, making the drive suitable for soft start applications. The output voltage is sinewave coded PWM operating at 16 kHz, which provides high motor torque, high efficiency and low noise. The KBVF is a full-featured drive, and due to its user friendly design, it is easy to install and operate. Simple trimpot adjustments eliminate the computer-like programming required on other drives; however, for most applications no adjustments are necessary.
