BETA phase converter is a device that converts single phase electrical to 3 phase supply. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical power supply.BETA Phase converter first converts 230v single phase supply to 440v through step up transformer and it again given to AC derive where the 3 phase AC supply is given to the electrical load through converting DC to AC.
