voltage.
For inverters with adjustable frequency and voltage, we call them frequency converter FR-E720-0.2K (application). The output waveform of frequency converter is analog sine wave
It is mainly used for speed regulation of three-phase asynchronous motor, also known as frequency converter.
For variable-frequency inverters with high waveform requirements mainly used in detection equipment of instruments and meters,
To sort out the waveform, you can output standard F sine wave, called freq
