ROV05-390K-S Application Field and Working Principle

TVS - Varistors, MOVs are transient voltage suppressors, commonly abbreviated as TVS, that are mainly used to protect circuit from surges and spikes. They are used in many different types of electronic devices to ensure that the circuit is not damaged by sudden events that affect the normal flow of power to them. Pivotal is  ROV05-390K-S series varistor specimens. Here we will discuss the application fields and working principles of this series.

Application fields of ROV05-390K-S

ROV05-390K-S is specifically designed for pulse and arc protection for devices. Its unique design and wide variety of specific voltage rates is able to highly improve the level of protection for devices. It is sufficient to assert that the intricate power needs of most electronic devices can be answered with the help of these varistors. For example, in welding machines, white goods, motor controllers, etc., the ROV05-390K-S can be used for providing protection from lightning caused sudden voltages and transients and also commutation surges.

Working principle of ROV05-390K-S

The working principle of ROV05-390K-S is based on the variable resistance of a Zener diode. When the voltage on a line reaches a certain level, called the breakdown voltage, current can flow through the Zener diode. The resistance of this diode is low when the voltage is low, and gradually increases when the voltage rises and at a certain value, called the clamping voltage, it reaches its maximum value. When the voltage on the line continues to rise, the current stays at the maximum value and the voltage is clamped, thus the desired protection is achieved.

Due to its wide resistance range, ROV05-390K-S is able to cover the entire AC and DC range of voltages, ensuring that it can provide protection for a variety of devices. What is more, this varistor is also able to provide protection from pulses and arcs generated from lightning strikes. 

Conclusion

ROV05-390K-S provides a reliable and efficient way to protect powered devices. Its working principle based on the variable resistances of a Zener diode helps achieve a wide range of voltage levels, while its pulse and arc protection are able to cover devices connected to especially vulnerable points in electronic devices.

With all of the advantages listed, ROV05-390K-Svaristor series is an effective remedy for protect against surge and spikes, a must-have measure of protection for any device.
