Abstract
In a piece of equipment deriving power from a three-phase power supply, a method and a connector provide a country-independent arrangement of connection pins to interface with the equipment, so as to provide one or more single-phase output voltages at designated pins. The connector includes a number of electrical terminals wired to the connection pins according to a country-dependent arrangement. In one embodiment, the connector includes one or more jumpers each configured to provide a short circuit between a designated pair of connection pins according to the country-dependent arrangement scheme. The country-independent arrangement provides a single-phase output voltage between 200-240 volts (RMS) across a designated pair of connection pins. In one application, a connector configured for the United States is used in conjunction with a 4-conductor cable having a U.S. conforming connector for plugging into a U.S. three-phase specification wall socket (e.g., NEMA). Similarly, a connector configured for Europe is used in conjunction with a 5-conductor cable having a conforming connector for plugging into a three-phase specification wall socket of the host European country (e.g., IEC 309).
