It is described an arrangement (100,300) for alternatively providing a 3-phase or a 1-phase power stream, comprising: a 3-phase power source (103,303) having a first (105,305), a second (107,307) and a third (109,309) power source output terminal; a switching section (111,311) adapted to selectively provide from the three power source output terminals (105,107,109,305,307,309) of the 3-phase power source: a 3-phase power stream at three arrangement output terminals (117,119,121,317,319,321) or a 1-phase power stream at two arrangement output terminals (115,123,315,323), different from the three arrangement output terminals (117,119,121,317,319,321). |
