Discovering the Power of MOV Varistors: Mornsun’s Comprehensive Guide

In the realm of industrial power supply solutions, Mornsun stands as a pioneer in introducing cutting-edge technologies. In this enlightening article, we delve into the world of MOV varistors, uncovering their role, applications, and the crucial protection they provide against overvoltage scenarios.

Understanding MOV Varistors: An Overview

MOV, or Metal Oxide Varistor, is a crucial electronic component designed to protect sensitive circuits from voltage spikes and surges. It is often utilized in parallel with other protection devices to divert excessive voltage away from the circuit, thereby safeguarding downstream components from potential damage.

The Power of MOV in Overvoltage Protection

MOV varistors act as voltage-clamping devices, meaning they maintain a relatively constant voltage across their terminals until a certain threshold is reached. When the voltage across the varistor exceeds this threshold, its resistance rapidly decreases, allowing it to conduct excess current and divert the surge away from the protected circuit.

MOV varistors are integral to modern electronics, safeguarding devices from transient voltage spikes caused by lightning strikes, power surges, or switching operations. They offer robust and reliable protection, ensuring the longevity and reliability of electronic equipment.


Mornsun’s dedication to innovation and excellence extends to the realm of MOV varistors, where they offer advanced solutions for overvoltage protection. By integrating MOV varistors into their power supply products, they reinforce their commitment to providing comprehensive solutions that not only deliver power but also ensure the safety and longevity of connected systems. Mornsun’s MOV varistors play a vital role in preventing damage from unexpected voltage fluctuations.
