In a location where three-phase and single-phase are required at the same time, it is possible to supply various loads with one generator. The three-phase and single-phase have independent winding structures, each equipped with AVR so there is no mutual influence on their outputs or properties. We offer a product that can assist in a number of places where three-phase and single-phase are simultaneously required such as construction site power supplies, disaster power supplies, and communication equipment power supplies.
