I had several dealings with other supposed manufacturers of Phase converters before finding American Rotary. All were very bad experiences and made me doubt the whole industry.
I finally found American Rotary and I can tell you there will be no other name at no other cost in future considerations for this product. I am more than thrilled with my AI50 unit as well as everyone who comes and can see it running in my warehouse. Pure quality and pure support in setting it up. My Electrician will now only suggest American Rotary.
I have a skid of past experiences of trying to find a company and this solution. Do yourself a favor and stop at this page and be thrilled and save yourself the grief and cash that it cost us till we found them.
