Not known Facts About VFD panel
Let us presume which the travel is working with a 480V electricity program. The 480V rating is “rms” or root-suggest-squared. The peaks with a 480V process are 679V. As you may see, the VFD dc bus has a dc voltage with an AC ripple. The voltage runs concerning approximately 580V and 680V. For the reason that motors revolutions for each minute
