Dual voltage operation means the unit which has that feature can be operated with one of two voltages. This is a feature that may lend itself to marketing a PC in Another Country where the line voltage (voltage at the mains) is different. The user is able to select an operating voltage, and it is usually done with a switch. Many PC's have the power supply fastened directly to the back of the case where the power cord goes in. (On most units, the power cord plugs directly into the supply.)Some of these power supplies have a small slide switch on them that permits selection of another operating voltage. A "115" or a "220" for example. By looking on the back of a given unit, one might see the switch that provides for the "dual voltage option" feature of that unit.
