Metal Oxide Varistor Symbol

The voltage and current characteristics of a varistor are nonlinear in nature.

Metal oxide varistor symbol.

The resistance of a varistor is variable and depends on the voltage applied. The metal oxide varistor. Modern varistor schematic symbol. The most common type of varistor utilise a metal oxide and hence they are often known as metal oxide varistors or mov for short.

Help identifying a varistor. Are external components required for hlk pm01. 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. The metal oxide varistor or mov is a voltage dependent nonlinear device that provides excellent transient voltage suppression.

Industrial high energy varistors provide a much higher surge and energy rating than regular movs metal oxide varistors and also possess various terminals to fit different assembly requests or conditions. Metal oxide varistors mov. 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. The word is composed of parts of the words.

However now that symbol is used for a diac. 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. Also the voltage and current characteristics of a varistor are suitable for both dc and ac supplies. Varistors are used as control or compensation elements in circuits either to provide optimal operating conditions or to protect against excessive transient voltages.

Need some help identify a varistor. The basics of metal oxide varistor mov along with its working and specifications are given and also its performance and other features. A varistor is a voltage dependent resistor vdr. This type is commonly known as the metal oxide varistor mov.

Since sic varistors had some serious drawbacks another type of. Help with identify varistor. Generally varistors are made from semiconductor materials.
