TVS (transient voltage suppressors), MOVs (metal oxide varistors), and V680LU80CP are three popular components used in power systems to protect equipment against voltage spikes. While each one performs a similar function, there are subtle differences between them that should be considered when choosing which one is best suited to a specific application. The following article will detail the application field and working principle of V680LU80CP.

Working Principle

V680LU80CP is a Nonlinear Metal Oxide Varistor designed to protect sensitive electronic equipment from lightning spikes and other transient over-voltage events. It is composed of zinc oxide disks that are isolated from each other and arranged in a ceramic case. Each disk is separated by a dielectric medium and as the voltage increases, the current through the device increases exponentially. The maximum current that can be safely passed by the V680LU80CP is 1kA, and the maximum surge energy needed to destruct the component is 40 joules.

Once the current reaches the 1kA maximum, the V680LU80CP will be destroyed and no longer be capable of functioning. As such, it is important to ensure that the V680LU80CP is properly sized to handle the expected surge peak voltage or current and to avoid exceeding the rated 1kA peak current.

Application Field

Due to its high peak current rating and expansive energy dissipation capability, the V680LU80CP is used in a variety of power system applications including over-voltage protection, surge current limitation, and line voltage noise reduction. The V680LU80CP is especially useful in high-voltage systems such as railway and solar energy systems, where high-surge current and voltage spikes occur frequently. It is capable of providing protection from lightning strike and other fast, high-current transients.

In the railway industry, V680LU80CP is often used as an over-voltage protector for track switches and other signal systems. The component is designed to help extend the life of equipment by limiting the amount of voltage and current that can enter the system. It is also typically used in photovoltaic systems, data systems, communication systems, low-voltage circuits, and consumer electronics.

Conclusion

The V680LU80CP is an important component in power system applications such as railway and solar energy systems, over-voltage protection, surge current limitation, and line voltage noise reduction. With a rated peak current of 1kA and a maximum energy dissipation capability of 40 joules, the V680LU80CP is capable of providing protection from lightning strikes and other fast, high-current transients. In conclusion, this component is an essential part of any power system that needs to be safeguarded against over-voltage events.
