As a well-known lightning protection brand in China, Anhui Jinli has been committed to the electrical safety of electrical systems and focused on lightning protection technology for electrical systems. It has 18 years of research and development experience. The backup protectors and surge protectors produced are of various types, novel styles, and high quality, which can meet the needs of different customers. To better serve customers, it should be noted that backup protectors and surge protectors are not the same. They are different in function, installation location, and role.

1) Surge protector. Also known as overvoltage protectors, they are used to protect electronic equipment from overvoltage damage. When voltage surges or transients occur in the circuit, surge protectors can guide these overvoltages to the ground or normal power supply. To protect the protected equipment, it is usually installed in front of the terminal equipment.
2) Backup protector. It is a backup power device that is used to provide a short-term power guarantee when the main power supply fails or the power supply is interrupted. It can enable the power equipment to maintain normal operation under abnormal conditions such as power outage, unstable voltage, high or low frequency, etc. Electrical equipment operates normally and is usually installed in front of a surge protector.

It should be noted that the back protector must be installed. It cooperates with the surge protector and is indispensable to protect the circuit from damage.
