The universal phase switching machine is used to supply a single-phase industrial and domestic installation with 230 V/50 Hz from a three-phase mains cable, in order to ensure a trouble-free supply of the single-phase electrical installation and to protect it from impermissible voltage fluctuations in the mains. Depending on the presence and voltage quality of the phases, the PEF-305 automatically selects the phase characterized by the best parameters and switches a single-phase load of any power to this phase: - measurement error of no more than 1%. - automatic phase switching when the voltage falls below 180 V AC - three-phase power supply L1-L2-L3 (L1 priority phase) the factory settings are: Switching voltage threshold (180 V AC), switching time (150 ms) and voltage hysteresis (10 V AC) This text is machine translated.
