Inverter speed adjustment skills training device

Inverter speed adjustment skills tr--ning device,AC asynchronous motor and control tr--ning device

I. Overview

This device is a advanced inverter speed regulating device launched on the basis of summing up the current frequency frequency speed adjustment tr--ning teaching equipment. This tr--ning device provides advanced operating platforms for the frequency conversion technology tr--ning and assessment. The inverter uses a widely used Mitsubishi FR-A540-0.75K inverter (users can also use other brands of inverter, price separately), with RS485 communication interface. The tr--ning desk can complete the related teaching and tr--ning of the "frequency frequency speed adjustment technology" course. In particular, the system provides open tr--ning teaching, which can fully cultivate students' actual hands -on ability and lay a solid foundation for participating in employment.
