Характеристики



Three phase voltage monitoring relay is used to protect the three-phase electric motors supplied from three-phase mains, against phase failure, incorrect phase sequence, voltage asymmetry, over and under voltage. RD-MVS series voltage relay are designedfor the three-phase system voltage controland load protection. It is possible to set minimum and maximum voltage, hysteresis, asymmetry and ON / OFFdelay.The LCD display and keyboard enableeasy parameters visualization and programming.
