PEF-319 universal automatic electronic phase switching device is designed to supply an industrial and domestic single phase 220/230/240 V, 50 Hz load from three-phase four-wire mains 3×380+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-319 will automatically select the optimum phase in limits range set by user and switch the single phase load supply to this phase:- If power is less than 6.6 kW (30 A), the load is energized directly from the PEF-319;- if power is more than 6.6 kW (30 A), the PEF-319 controls the magnetic contactor (MC) single phase coils of the corresponding power (MC are not included in supply complete package). The maximum and minimum voltage limits are set by user adjusting the potentiometers on the front panel as per requirement.
