I have an ultra-sonic cleaner that came from Germany. The power supply states 230V, 50/60 Hz. The power supply cord is European. Does this require a transformer to use on 230v US, or is it possible to change the European plug to a US NEMA 6-15 style 230v plug? I believe Europe provides 230v on one terminal of the plug, whereas the US provides 115v to two terminals. Thanx.
