It ensures uninterrupted power supply for highly critical single-phase consumers and protects them from unacceptable voltage fluctuations in the network.
Depending on the availability and quality of the voltage on the phases, PEF-319 automatically selects the most optimal phase based on user-defined settings and connects the single-phase load of any capacity to it:
