Working principle of product:
• Surge protector is an indispensable device in lightning
protection of electronic equipment. It used to be called "lightning
arrester" or "overvoltage protector". The function of surge
protector is to limit the transient overvoltage to the power line
and signal transmission line within the electric pressure range
that the equipment or system can bear, or to inflow the powerful
lightning discharge into the ground. The protected equipment or
system is not damaged by impact.
