How to make a 220V power supply?
I do not understand electrics at all. How to make a power supply with parameters of 220 volts and 0.5 amperes? What elements are needed, what schemes are there, or where to go to clarify the issue?
And why is the power supply 220V and 0.5 A? You already have 220V in the outlet, and the amp will take as much as you need! Maybe you put it wrong or I misunderstand, explain what caused your question!
