Three-phase electric power is utilized in electrical grids around the world to transfer power. Phase converters are typically used to convert single-phase electric power to 3-phase electricity, which is most often used to power large machinery, elevators and other industrial equipment. Simple in design, phase converters work as motors to convert power from single-phase to 3-phase. You can find both rotary or static phase converters, depending on your preference. Zoro also features a selection of transformer accessories and voltage converters.
