ROV20-560L

Varistors, MOVs, and ROV20-560Ls all serve the purpose of protecting electrical components from getting damaged from high voltages by redirecting current from them. Varistors are voltage dependent resistors that have a non-linear current-voltage curve and tend to have much higher resistance below a certain voltage threshold than above it, while MOVs (Metal Oxide Varistors) are similar to Varistors, although they come with the added benefit of durability and better temperature stability. Lastly, ROV20-560Ls are special types of MOVs with a greater capability to absorb energy when voltage spikes, and due to their reliability and effectiveness, they are often used in industrial practices and in many commercial applications.

While the application field of Varistors, MOVs, and ROV20-560Ls is quite large, they are most commonly used in electrotechnical and industrial equipment, such as switching power supplies, electronic circuits and power transformers, in order to protect them from overvoltages. Additionally, they are also often used in computer and telecommunications networks, as well as in electrical appliances and consumer products, often in the form of a two-wire component such as a voltage clamp or ROV20-560L. Furthermore, they are also commonly used in lightning protection systems in order to prevent electrical damage that could occur during a lightning strike.

Regarding the working principles of all three types of voltage suppressors, Varistors and MOVs work by redirecting current from its input to its output when a input voltage spike is detected. These can usually handle up to 1500V and are often used in low-power applications. ROV20-560Ls on the other hand are designed to be able to absorb over 3,000V, and have an internal thermal cycling mechanism, which allows for a greater level of protection. They are designed to “clamp” incoming voltages more quickly and accurately than Varistors and MOVs, and due to their ability to absorb greater levels of energy, they are more suitable for higher-power applications.

In conclusion, Varistors, MOVs, and ROV20-560Ls are all important voltage surge suppressors that play an important role in protecting electronic components from voltage spikes. Varistors and MOVs are more suitable for low-power applications, while ROV20-560Ls can absorb greater amounts of energy and are more suitable for higher-power applications. All three types of voltage suppressors can be found in a range of applications, including computer and telecommunications networks, electrical appliances and consumer products, lightning protection systems, and industrial electrical equipment.
