Overvoltage Absorber

Overvoltage absorbers, also known as surge absorbers or surge suppressors, are devices used to protect electrical and electronic equipment from voltage spikes or surges. These surges can occur due to lightning strikes, power grid fluctuations, or switching operations.

The main function of an overvoltage absorber is to divert excess voltage away from sensitive equipment, preventing damage or malfunction. They are typically installed in parallel with the equipment they are protecting.

Overvoltage absorbers work by providing a low-impedance path for the surge current to flow through. They are designed to have a higher voltage rating than the equipment they are protecting, allowing them to absorb the excess voltage without damaging themselves.

There are different types of overvoltage absorbers available, including metal oxide varistors (MOVs), gas discharge tubes (GDTs), and silicon avalanche diodes (SADs). Each type has its own characteristics and is suitable for different applications.

In summary, overvoltage absorbers are essential components in electrical and electronic systems to protect equipment from voltage surges. They help ensure the reliable operation and longevity of sensitive devices by diverting excess voltage away from them.
