AUTOMATIC ELECTRONIC PHASE SELECTOR PEF-320

PEF-320 universal automatic electronic phase switch is designed to supply an industrial and domestic single phase 230 V, 50 Hz load from three-phase four-wire mains 3х400+N in order to maintain uninterrupted power supply of essential single-phase loads and protect them against unallowable voltage variations in the mains.
According to the voltage presence and voltage quality on the phases, the PEF-320 will automatically select the optimum phase in limits range set by user and switch the single phase load supply to this phase. It is possible to connect to one of the phases of the electric generator and inverter. The maximum and minimum voltage limits are set by user.
