The entire process was as easy as could be from sizing of the converter to sales advice and shipping it couldn’t have gone smoother. Once the proper single phase power was installed the process of connecting the ADX-20 went really smooth. The enclosed instructions perfectly outlined the steps and in less than 30 minutes we were up and running. This unit runs so quietly we only know it’s running because our CNC is operating, you don’t even hear it over ambient noise of the small shop. Thanks for making a quality product that I am sure will last for years to come.
