Universal automatic electronic phase switch PEF-319

Model: 026.004.131
Universal automatic electronic phase switch PEF-319
Country of origin: Россия
The PEF-319 universal automatic electronic phase switch is designed to supply an industrial and domestic single phase 230/240 V, 50 Hz load from three-phase four-wire mains 3х380+N in order to maintain uninterrupted power supply of essential single-phase loads and protect them against unallowable voltage variations in the mains.

 pcs

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 starters (MS) single phase coils of the corresponding power (MS are not included in supply complete package).
