A surge protector is a device that is installed in the circuit of electrical or electronic equipment to protect its safe operation. Typically, a surge protector serves to limit overvoltage in a circuit, thereby protecting the equipment. It has a high response speed and energy absorption capacity, and can be fused in time when the circuit is subjected to overcurrent or overvoltage impact, to protect the equipment from damage.
Surge protectors are widely used in a variety of fields, such as industry, communications, transportation, medical and so on. In the industrial field, surge protectors are often used in industrial process control systems to keep equipment running properly and ensure data accuracy. In the medical field, surge protectors are used in the protection of medical equipment to protect patients from the dangers of current or voltage surges. In the transportation field, surge protectors are widely used in equipment such as signal lights, control systems and construction equipment.
Surge protectors are also regarded as one of the essential components in modern circuits. With the continuous development of electronic technology, the performance of surge protectors has also been greatly improved. Nowadays, more and more surge protectors have higher protection level, which can effectively protect various equipments from overcurrent and overvoltage. Therefore, the application of surge protectors is very broad.
