Description
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 3×380+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 contactors (MC) coils of corresponding wattage.
