Sorry guys for taking your time,
but thanks for your remarks. I know that using a three phase output is better then a single phase. But the client seems allergic of three phase VFD's. That's why I am asking again and again. I have searched the google. But found only one, and our client wants a single phase VFD of 2.2 & 2.8KW. I found one VFD of 1.5KW but according to his demands I am tired of searching for the VFD. Well thanks guys now I will handle this situation. Thanks Once again
