I bought one of these "excitech" routers before they changed the name.. These are also known as as xhyc but they changed the name.
I learned the hard way that these routers they are selling have different requirements for electrical in europe and china than we have here in the U.S. It cost me almost $6,000 dollars to convert our building to 3phase after spending $2,000 on a phase converter only to find out it wouldnt work with the chinese wiring. They tell you 220 but its 250 and the amperage requiremnets are way off.. they cant provide an electrical schematic or a wire diagram or anything.
