TVS - Varistors, MOVs are widely used in various electronics circuits, which can protect the circuit from over-voltage or over-current, and the device is also used to reduce the voltage drop due to surge. ROV20H390L-2 is a TVS - Varistors, MOVs device that provides over-voltage protection for a variety of equipment and applications.

Application Field

The ROV20H390L-2 TVS - Varistors, MOVs device can be applied in a variety of applications, including electronic control systems, communication systems, home appliances, automobiles, instruments, converters, etc. It can protect the circuit in the field of power line, overload surge, over voltage surge, short circuit, grounding protection, etc. For example, it can provide protection for the circuit when the air conditioner power is suddenly shut down, the anti-interference performance can be improved if it is applied in the communication system and the motor can be protected from being burned down when the electrical machinery has sudden impact.

Working Principle

ROV20H390L-2 TVS - Varistors, MOVs device has 20mm diameter, can be connected in series and can withstand voltage value up to 390V. It is composed of metal oxide varistors and a movable conductive element. When the over-voltage is detected, two metal plates in the device will instantly make contact and the current will be quickly diverted through the body, thus limit and reduce the voltage jump and protect the corresponding components in the circuit from excessive current and over-voltage. The device can be used in single-mode, multi-mode and common mode, it has a good effect of responding to impulse current and it also has great stability and self-recovery ability.

In conclusion, ROV20H390L-2 TVS - Varistors, MOVs device can protect different kind of circuit effectively and also has good stability and self-recovery ability. It can be used in many application fields with a satisfactory result thus it is a very ideal over-voltage protector.
