AC VVVF DRIVE MODULE:

Introduction:

• VVVF Drive Modules are used for Speed Control of AC Induction motors/ Slip ring motors with the concept of keeping V/F ratio constant.
• The Drive modules additionally provide power saving in turn they reduce the current drawn by Induction motors.
• This Model is the Industrial/Educational model suitable for demonstrating to students the complete knows of the Basics, Speed control, Study of all parameters & variation of frequency up to 500Hz & Maintenance of these motors packaged in small rating.
• Students can make connections of their own with the help of the terminations provided.

Technical Specifications:

• Power ratings available       : 1KW / 2KW/ 5KW/ 10KW
