    How to select Rockwell AB inverters? How to select Rockwell AB inverters? During work, some customers often fall into the distress of inverter selection. In fact, before selecting a model, you can first understand the working principle of the inverter. The frequency converter is an electric energy control device that uses the on-off effect of power semiconductor devices to convert a commercial frequency power supply to another frequency. The frequency converter we use now mainly adopts AC-DC-AC mode (VVVF frequency conversion or vector control frequency conversion).
