Vemer PSR400 phase control relay, for DIN bar mounting, which detects the exact phase sequence in three-phase systems and the voltage unbalance caused by the decrease or absence of one of the phases.
Particularly useful in all those cases where it is essential to respect the phase sequence during connection or to prevent high oscillations of the mains supply voltage.
The sensitivity can be adjusted by means of the trimmer on the front of the device between 95% and 70% of the nominal value, in order to adapt it, during installation, to the value of the mains voltage unbalance that can be tolerated.
