Power Supplies
The power supply transformer raises or lowers the voltage as needed. Most devices require stepped down voltage from standard AC outlets, which output 100 to 240 volts, to a much lower amount. Some transformers, however, will step up the voltage and isolate the incoming and outgoing circuits.
