ROV07-621K Datasheet/PDFTVS(Transient Voltage Suppressor) - Varistors, MOVs(Metal Oxide Varistors) are usually used in power line protection circuit design. ROV07-621K is an 80KA surge protection module belongs to this category. The module works by providing a large amount of energy that is able to withstand voltage spikes caused by lightning or other sources. By reducing the amount of energy reaching sensitive components, it helps to improve the reliability of the equipment.
ROV07-621K is a temperature compensated Metal Oxide Varistor (MOV), made from sustain nano-materials, with more reliable and stable performance. The component is lead-free, RoHS compliant, and UL approved. The maximum voltage of the device is 621V, and the maximum current is 80KA. This makes it suitable for both residential and industrial applications, such as AC/DC power lines, telecommunications, automotive electronics, and infrastructure.
ROV07-621K includes two parts: a ceramic body and a zinc-oxide varistor element. The ceramic body acts as the structure of the device and the zinc-oxide varistor element absorbs the energy of the voltage spike, thus protecting the equipment from damage. The ceramic body provides a grounded electrical connection for the varistor element, allowing it to react quickly to high currents. The zinc-oxide element also helps to manage the temperature of the module to provide an effective operation.
The working principle of ROV07-621K is quite simple. When a voltage spike occurs, the module is triggered and it immediately begins to absorb the energy of the spike. This causes the element to become warm, and this heat helps dissipate the energy of the spike. The energy absorbed is stored as electrical potential energy, which helps make the module more resistant to subsequent voltage spikes. At the same time, the stored energy is also limited, ensuring that the module does not overheat and cause any permanent damage to the equipment.
ROV07-621K is a great choice for power line protection applications. The module is designed to effectively absorb voltage spikes of up to 621V and 80KA, making it suitable for both residential and industrial applications. The device has a simple design and is easy to install in most commercial or industrial settings. With its robust design and reliable performance, ROV07-621K is a great choice for power protection in any application.
