Surge Protector AVS5A Voltage Protector

Welcome to TuFang Store - Electrical SeriesSurge protective deviceSurge protector, also known as lightning arrester, is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines. When the electrical circuit or communication line suddenly generates peak current or voltage due to external interference, the surge protector can conduct shunt in a very short time, thereby avoiding damage to other equipment in the circuit caused by surges.Surge protector is suitable for protecting indirect lightning, direct lightning impact, or other transient overvoltage surges in power supply systems with AC 50/60HZ and rated voltage 220V/380V. It is suitable for the requirements of surge protection in household, residential, tertiary, and industrial fields.Basic characteristics1. High protection flow rate, extremely low residual voltage, and fast response time;2. Adopting the latest arc extinguishing technology to completely avoid fires;3. Adopting temperature control protection circuit with built-in thermal protection;4. Equipped with power status indicator to indicate the working status of the surge protector;5. Rigorous structure, stable and reliable operation.The most primitive surge protector with a claw shaped gap appeared in the late 19th century and was used for overhead transmission lines to prevent lightning strikes from damaging equipment insulation and causing power outages. In the 1920s, aluminum surge protectors, oxide film surge protectors, and shot type surge protectors emerged. In the 1930s, tubular surge protective devices emerged. In the 1950s, silicon carbide lightning arresters appeared. In the 1970s, metal oxide surge protectors appeared again. Modern high-voltage surge protectors are not only used to limit overvoltage caused by lightning in power systems, but also to limit overvoltage caused by system operation. Since 1992, the industrial control standard 35mm guide rail plug-in SPD lightning protection module represented by Germany and France has been introduced to China on a large scale. Later, the integrated box type power supply lightning protection combination represented by the United States and the UK also entered China.
