1-Phase AC - DC

Single-phase power supply is a two-wire alternating current (AC) power circuit. Typically, there is one power wire - the phase wire - and one neutral wire, with current flowing between the power wire (through the load) and the neutral wire. AC-to-DC converters with overload protection are suitable for powering heavy-duty equipment. A switching DC power supply provides a range of power ratings, output voltages, and styles for applications with changing power demands. Residential homes are usually served by a 1-phase power supply.
