DYTSB-011 Variable frequency speed adjustment training platform

This device uses a typical high-performance, multi-functional FR-A740 variable frequency speed regulator (380V, 0.75kW) recently launched by Japan's Mitsubishi Company as the host machine, and is equipped with a pulse encoder motor braking speed measurement system. The entire equipment can complete open-loop and closed-loop system experiments as well as all functional experiments of variable frequency speed regulators. The open structure allows students to comprehensively learn and master the structural principles, inspection and m*ntenance of variable frequency speed regulators. It is suitable for supporting teaching and open experiments in automation majors in colleges and universities, vocational schools, and technical schools.
