TVS, MOVs and Varistors are three of the most important components of overvoltage protection. ROV05-820K-S is a lightning surge Varistor which is suitable for different application fields and works according to working principles.

Application Field of ROV05-820K-S

ROV05-820K-S Varistor is often used in communication systems, and they can protect from indoor lightning overvoltage and also from electromagnetic interference (EMI). This lightning surge varistor can be used for communications and networks, such as wireless LAN, data bus, Bluetooth, cabling networks, power supply systems, etc. It also can be used in industrial automation systems, such as PLCs, CNCs, SCADA, etc. Moreover, it can be used in automotive systems, such as the charging circuits of automobiles, HVAC systems, anti-lock brake systems, airbags, charging ports, body control modules, transmission control module, etc.

Working Principle of ROV05-820K-S

ROV05-820K-S Varistor works according to the non-linear characteristics of the varistor material, when the varistor is connected to a power supply, and the input voltage is below its rated voltage, the varistor keeps its high resistance, which blocks current flows. However, when the input voltage is above its rated voltage, the varistor changes its resistance from high to low, and it allows the current to flow through the varistor and protect the circuit from over-voltage. The varistor material features high energy absorption capacity, low inductance, fast response time, and excellent electrical characteristics for over-voltage protection.

ROV05-820K-S Varistor also features high reliability and easily system integration, low energy consumption, long service life, and good electrical performance. The varistor can absorb and disperse large amount of high energy over-voltage surge in a short time, which effectively protects the connected circuit from over-voltage damage.
