WEET Shares An Article About What Varistors Are and Their Functions
A resistance device with nonlinear volt ampere characteristics, made of semiconductor materials, is called a High Power DIP Varistor.
The resistance material of WEET WVA Varistors is semiconductor, so it is a variety of semiconductor resistors.
The widely used "zinc oxide" (ZnO) varistors are composed of divalent element (Zn) and hexavalent element oxygen (O) as their main materials, hence they are also known as Metal Oxide Varistor China Dipped Radial MOV.
The over voltage protection of Radial Leaded Zinc Oxide Varistor 6KV3KA Varistors can be used in power protection, communication equipment, industrial control systems, and other fields. The lightning protection of
Round Zinc Oxide Varistor is mainly used for outdoor power systems and electrical equipment. The over current protection of DIP varistor 5D180K diameter 5mm can be used to protect power equipment, large electromagnets, and large motors from equipment damage caused by over current.
The role of WEET WVA Radial Leaded Metal Oxide Varistor in electronic products is mainly reflected in the following aspects:
1. Lightning protection:
MOV Zinc Oxide Varistor 5mm Disc Varistors can respond to and shunt lightning strikes or other overvoltages, protecting other components in the circuit from the effects of lightning strikes.
Varistors play different roles in different situations, but of course, in order for them to perform their intended function, it is necessary to use high-quality and high-performance Round Zinc Oxide varistors.
2. Over voltage protection:
The main function of a 6KV 3KA MOV Metal Oxide Varistor Surge Protection varistor is to clamp the voltage to a relatively fixed voltage value through its nonlinear volt ampere characteristics when the circuit is subjected to over voltage, thereby absorbing excess current to protect electronic components.
When the voltage in the circuit exceeds the threshold of the Varistor With Straight Leads or Kink Leads, its resistance value will sharply decrease, thereby converting the excessive voltage into a relatively small voltage to prevent damage to subsequent circuits or electronic components caused by over voltage.
3. Over current protection:
In some applications, High Power DIP Varistor can also be used for over current protection. When the current in the circuit exceeds the rated current of the Radial Leaded Zinc Oxide Varistor 6KV3KA, the resistance value rapidly decreases, diverting the additional current to ground and protecting other electronic components.
