Technical Datasheet (PDF)

PEF-301 universal automatic electronic phase switch is designed to supply industrial and household appliance single phase 220 -  230V/50Hz loads from three-phase four-wire mains 3x380+N with the purpose of maintaining uninterrupted power supply of essential single-phase loads and protect them against unallowable voltage variations in the mains.

Depending on voltage presence and voltage quality on phases, the PEF-301 will automatically select the optimal phase and promptly switch the single phase load supply of any wattage to this phase:

  • Loads of wattage up to 3 kW (up to 16A) get power supply directly from PEF-301
  • When wattage exceeds 3 kW (16A), PEF-301 phase switch will control the magnetic starters (MS) coils of corresponding wattage (MS can be supplied optionally)
