Varistor technology has been in use for decades, but it is only recently that it has become a viable option for use in power-related applications. Today, varistors can be used as surge protection components in a wide range of applications, from consumer electronics to industrial power systems. ROV07H180M is one such modern varistor and this article will look at the application field and working principle of the device.

What is ROV07H180M?

ROV07H180M is a metal oxide varistor (MOV) module, a product of Littelfuse, Inc., that offers excellent protection against surges and overvoltages. It is designed for three-phase applications mainly in commercial and industrial power systems, but its wide voltage range can be used in many applications. The module consists of three varistors in series and can be connected either in parallel or in series to improve the overall protection ability.

Application Field of ROV07H180M

ROV07H180M is applicable in three-phase power distribution systems either in commercial or industrial applications. The device can be used as a surge protection component in power lines, such as between the utility and the service entrance, between the service entrance and the load, or between different power distribution systems. Furthermore, the product can be used in applications that require a higher surge protection level, such as motor control systems, lighting systems, and so on.

Working Principle of ROV07H180M

A varistor is a semiconductor device that is used to protect against electrical overvoltages. It consists of a junction of two different types of semiconductor material, usually a metal oxide-semiconductor junction, and works by blocking voltage when it passes a certain threshold. The metal oxide layer acts as a resistor, and when the voltage across the junction reaches a certain amount, typically between two and ten volts, it will start to conduct, effectively reducing the amount of voltage to the load. This is known as the “breakdown voltage”, and is used to protect the load from damage.

When an overvoltage occurs, the overvoltage will cause the varistor to go into conduction, thereby reducing the voltage applied to the load and protecting it from damage. When the voltage return to normal, the device will return to its non-conducting state, allowing power to flow as normal.

Conclusion

ROV07H180M is an excellent option for surge protection in power distribution applications. The device is designed with a wide voltage range, is easy to install, and provides excellent protection against overvoltages. The working principle of the device is based on the breakdown voltage of the metal oxide layer, and when the voltage reaches a certain amount it will start to conduct, effectively reducing the amount of voltage to the load.
