Get contact details & address of companies manufacturing and supplying MOV, Metal Oxide Varistor across India. A Metal Oxide Varistor or MOV is the blue or orange-colored circular component that you can commonly spot on the AC Input side of any Power Supply Circuit.The Metal Oxide Varistor can be considered as another type of variable resistor that can vary its resistance based on the applied voltage across it. a maximum varistor voltage change of ± 10 % at 1 mA When more than one pulse is applied, the duty cycle must be so that the rated average dissipation is not exceeded. In … Voltage divider circuit is the basis of construction of Potentiometer. Some LA Series model numbers are available with clamping voltage selections, designated by a model number suffix of either A or B. In this case, the value of the typical leakage current will be lesser than a specified value.
