TVS - Varistors, MOVs come in various shapes and sizes. To get a better understanding of the application field and the operation principle, let’s start with discussing the ROV14H560K-2 device.

This device is a Radial Leaded Varistor, which belongs to the family of Varistors or Metal Oxide Varistors (MOVs). Varistors are energy-limiting components, used to protect equipment and circuits from transient voltage surges. This type of protection is very important in many electrical systems. Examples of applications are low-voltage dielectric systems and telecom systems.

The ROV14H560K-2 is a 14mm radially-mounted device. It has an insulation voltage of 1,500V and a maximum clamping voltage of 560V. This device can handle currents of up to 250 amps.

Varistors work on the principle of nonlinear resistance. They are able to offer very high resistance with normal voltage levels, but when voltage levels reach a certain threshold, they become reversely conductive and start to rapidly dissipate energy.

The ROV14H560K-2 has a rated dissipation energy of 125 joules, which indicates that it can quickly absorb up to 125 joules of energy. So, when a high surge voltage is applied to the device, it will limit the voltage across the exposed terminals and dissipate the excess energy while protecting the internal circuitry.

The device is designed to start clamping at a very low voltage (as low as 14V for the ROV14H560K-2 device) and then limit the voltage across the protected circuits to its maximum clamping voltage (560V for this device).

Varistor technology has been widely used in many applications, such as telecommunications, household appliances, power supplies, uninterruptible power supplies, automotive systems and many others. In most applications, the varistor is used to protect the circuits from overvoltage or overcurrent conditions.

The Rov14H560K-2 is a reliable, economical and easy to use varistor, making it an excellent choice for a variety of applications. It is also highly recommended for systems with high power loads, as it is able to absorb large amounts of energy and dissipate it safely.

In conclusion, the ROV14H560K-2 is a reliable, economically priced varistor designed specifically for overvoltage and overcurrent protection, making it an ideal choice for many applications. With its low maximum clamping voltage, it is highly suitable for a variety of applications. Its high dissipation energy rating allows it to rapidly dissipate excess energy, making it an effective protection device. And with its easy to use design, it is highly recommended for even the most demanding protection needs.
