I build a machine that uses 120v 10a single phase. The load is resistive so the frequency won't make a difference. The PLC has its own power supply that converts 120-240vac into 12vdc. The resistive load uses a transformer that drops the 120vac to 6vac. I have a client in Australia interested in purchasing some of these machines but I am unfamiliar with electrical requirements outside of the USA. Is there a simple power supply that I can recommend to my client? I'd rather not rework the electrical system at this point.
