Allow us to suppose the drive is operating over a 480V electrical power program. The 480V score is “rms” or root-mean-squared. The peaks with a 480V method are 679V. As you may see, the VFD dc bus has a dc voltage having an AC ripple. The voltage operates amongst about 580V and 680V. Click here for more info about VFD panelAlthoff was a satisfa
