KB Electronics Chassis IP-20 AC Drives 

KB offers 33 Variable Frequency Chassis IP 20 Drives in two categories.

The following features are common to both drives:


Sensorless Flux Vector Compensation with Static-Auto-Tune to provide excellent speed regulation with high torque loads throughout the entire speed range. Auto energy saving at light loads. Smooth motor torque.

They are designed for applications that may or may not require digital programming and a digital display. Hybrid KBVF & Digital KBDF AC Drives provide variable speed control of standard 3 phase AC induction motors from 1/8 to 5 horsepower.
