The YX743FPS220 automatic electronic phase switch is designed to supply an industrial/ appliance single-phase 220V/50Hz load from three-phase four-wire mains 3x380+N in order to maintain an uninterrupted power supply of essential single-phase loads and protect them against unallowable voltage variations in the mains. To this end a single phase load is connected into the three-phase mains with the interposition of the YX743FPS220. According to voltage presence and voltage quality on phases, the YX743FPS220 will automatically select the optimum phase and switch the single phase load supply to this phase.
