1. Product characteristics:

 

This device uses a typical high-performance and multi-function FR-A740 variable frequency frequency frequency speed regulator (380V, 0.75kW) as the host, and the outer pulse coder electrical mechanism speed measurement system. The entire device can complete all functional experiments of the opening and closed -loop system and the frequency conversion speed. The open structure allows students to comprehensively learn and master the structure principles of frequency adjustment speed, detection and m--ntenance. It is suitable for large and high school colleges, vocational schools, and technical school automation professional supporting teaching and open experiments
