What is ROV14H820k and its application field and working principle? This is a question we often hear asked by professionals and knowledgeable individuals interested in circuit protection devices. ROV14H820k is a voltage-dependent overvoltage protector (TVS) designed for use in high-power applications. ROV14H820k is a Varistor (or MOV, Metal-Oxide Varistor), designed to provide overvoltage protection by diverting surge current away from the protected circuit. Its application field and working principle are discussed in more detail here.

Metal-oxide varistors (MOVs) are one of the most popular and successful types of voltage-dependent overvoltage protection devices available. As the name suggests, the technology is based on the utilization of metal oxides which are composed of several components. When a voltage is applied across the two contacts of the varistor, the metal oxides in its core will redistribute and change their electrical properties. This results in the gain or reduction of current depending on the applied voltage. In addition, the metal oxides also form strong electrical bonds, allowing them to absorb and dissipate large amounts of energy.

ROV14H820k is a voltage-dependent overvoltage protector (TVS) designed for high power applications. It has a high surge energy rating of up to 40 Joules, meaning it can withstand large surges of current without being damaged. It also has a low leakage current of 35nA which ensures that it does not interfere with the normal operation of the connected electronic device. ROV14H820k is also designed for a wide range of applications, including AC/DC motors, industrial PCs, vending machines and more.

The working principle of the ROV14H820k Varistor is relatively straightforward. When a large surge of current passes through the device, it filters out the excess energy and dissipates it as heat. The filtering of the current prevents it from damaging the connected electronic device. This is done by quickly shifting the electrical properties of the metal-oxide core of the Varistor. When a surge of current is detected, the metal-oxide core will become more conductive, allowing the current to be diverted and dissipated.

ROV14H820k Varistors are designed for a wide range of applications, such as valve circuits, transformer circuits, AC/DC motors and more. They are also ideal for powering different electronic devices, such as vending machines, industrial PCs, and more. In addition, the high surge energy rating ensures that the Varistor can withstand large surges of current while still providing excellent protection. The low leakage current also ensures that the device will not interfere with the normal operation of the connected electronic device. Overall, ROV14H820k Varistors are a reliable and effective choice for surge protection applications.
