Surge protectors are devices used to protect electronic equipment from damage from power surges. They are installed between the equipment and the power source, and they work by absorbing or redirecting the excess energy from a power surge. When properly installed, surge protectors can help extend the life of electronic equipment and prevent costly repairs. There are a number of different types of surge protectors on the market, so it is important to choose one that is suitable for the specific needs of the equipment. In most cases, surge protectors need to be replaced after they have been used to absorb a surge, so it is important to have a replacement unit on hand. With proper maintenance, surge protectors can provide many years of protection for electronic equipment.
