Metal Oxide Varistor Symbol

How to choose the right metal oxide varistor mov 0.

Metal oxide varistor symbol.

Help with identify varistor. 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. Are external components required for hlk pm01. This type is commonly known as the metal oxide varistor mov.

Generally varistors are made from semiconductor materials. The resistance of a varistor is variable and depends on the voltage applied. Varistors are used as control or compensation elements in circuits either to provide optimal operating conditions or to protect against excessive transient voltages. Metal oxide varistors mov.

The voltage and current characteristics of a varistor are nonlinear in nature. Since sic varistors had some serious drawbacks another type of. The most common type of varistor utilise a metal oxide and hence they are often known as metal oxide varistors or mov for short. Also the voltage and current characteristics of a varistor are suitable for both dc and ac supplies.

The basics of metal oxide varistor mov along with its working and specifications are given and also its performance and other features. 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. Help to choose fuse varistor and or tvs diode. Varistors can be considered to be a form of resistor in which the resistance changes significantly with the applied voltage.

The metal oxide varistor. A varistor is a voltage dependent resistor vdr. In its early days the varistor was represented as two diodes placed anti parallel to each other as shown in figure due to its diode like behaviour in both directions of current flow. Need some help identify a varistor.

The metal oxide varistor or mov is a voltage dependent nonlinear device that provides excellent transient voltage suppression. Help identifying a varistor. Modern varistor schematic symbol.
