ROV05H121K-S-2 Application Field and Working Principle

TVS (Transient Voltage Suppressor) Varistors, MOVs (Metal Oxide Varistors) are widely used in many high-voltage applications such as power supplies, circuit protection and other related components. The ROV05H121K-S-2 is a specially designed MOV varistor with excellent fire-resistance and improved dielectric absorption characteristics. It can effectively suppress transient voltages that are higher than normal standard voltage.

Application Field

The ROV05H121K-S-2 is used in a variety of applications such as equipment protection, reverse polarity protection, over voltage protection, power line protection, surge protection, high voltage protection and lightning strike protection. It is also widely used in a variety of industrial and commercial applications including automotive, aircraft, defense electronics, communications, medical devices, power, home appliances and many others.

As its name suggests, the ROV05H121K-S-2 is highly suitable for electrical circuits that require higher levels of fire-protection as compared to traditional MOVs. The ROV05H121K-S-2 is specifically designed to safely dissipate large amounts of energy into the circuit in order to prevent possible permanent damage to the electrical components connected to the circuit.

Working Principle

The ROV05H121K-S-2 works on the principle of transient voltage suppression (TVS). When a voltage greater than its rated value is applied to the MOV, it experiences a momentary increase in its electrical resistance, this increase in resistance prevents the excess energy from passing onto the circuit. To further enhance its fire-resistant capabilities, the ROV05H121K-S-2 is designed with a special type of polyethylene insulation which is thermally resistant and helps to limit the dissipation of the energy into the surrounding environment.

The ROV05H121K-S-2 is designed with a unique structure that uses a monolithic component consisting of multiple layers of conducting material. This design helps to improve the capacitance value of the MOV varistor, which prevents it from saturating due to high surge voltages. The ROV05H121K-S-2 is also designed with a high energy absorptive capacity, which helps in dissipating excess energy into the circuit and prevents damage to the downstream components.

Conclusion

The ROV05H121K-S-2 is a highly efficient and reliable MOV varistor designed to provide superior protection for high voltage applications. Its excellent fire-resistance and improved dielectric properties make it ideal for a variety of applications. Additionally, its unique structural construction ensures a high energy absorption and dissipation capacity which prevents electric shocks and circuit damages.
