You are in Europe, yes? Unlike Mean Well which makes drivers for all AC inputs that can be used almost anywhere in the world, I believe Inventronics divides their's into low-voltage and high-voltage models to improve the efficiency of their low-voltage models. But I think there are some mistakes on their website because the EBV-500 is stated as being "suitable for North American use" but its input voltage is 176-305V AC, so I can't see how that would work on 110-115V mains. The ESD-320 is even more confusing because the datasheet lists its minimum input voltage as 249V AC, so that wouldn't even work in Australia where we have 230V mains. Yet it is listed as "suitable for North American use". All I can think of is that they are intended to be used on three-phase power, but I don't know for sure. I wish I could help you but I am just as confused!
