1 DESCRIPTION AND OPERATION

1.1 APPLICATION

The PEF-319 universal automatic electronic phase switching device 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.

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).

The maximum and minimum voltage limits are set by user.

1.2 TECHNICAL SPECIFICATION
The technical characteristics of phase switch PEF-319 are resulted in the tables 1 and 2.
