VCR – Voltage

The VCR voltage control relay is a 2 DIN module, to activate an external circuit relay detects the exact sequence of the phases in three-phase systems and the unbalance of the voltages caused by the decrease or lack of a phase. This device is applied in all those cases in which it is indispensable to respect the phase sequence during the installation or prevent high oscillations of the power supply voltage in the network.
