We are using the AmericanRotary phase converter to power our 230 volt 3 phase truck tire changers. This allows us to stock 3 phase units and if single phase power is required we simply add the American rotary converter to the package. This system not only works flawlessly but is very simple to install and does not take away from our machine in a cosmetic sense. Their technical support team has been very helpful particularly in helping us choose the correct size unit for our application. I would recommend American Rotary’s products and services to anyone.
