I have a device that runs on a typical US outlet at 120V and on the power supply I can can flip a switch to run it off 220V. I assume the switch moves back and forth between two different transformers?
If I wanted to buy or design a power supply for a higher power system to run off both 120V and 240V without having a human interact so that I could plug it into a 120V outlet or a 220V outlet without thinking about it, would I need something that automatically selects which transformer to use so I don't have to do it manually, or are there power supplies that have that wide of a voltage input range? How is it typically done? I'll probably be pulling 10-25 Amps. I realize I haven't added many details such as output voltages, etc, but I'm just focused on the general design and idea of something that can run off 120/220V. Thanks in advance!
