VTL7 Series DC Surge Protection Device
Description:
VLT7 series surge protective devices have reliable voltage protection level, super surge discharge capacity and safety overload capacity, which are used for lightning protection of photovoltaic power generation system. The product is equipped with high-energy mov chip, so when the system has overvoltage due to lightning
stroke or other reasons, it can introduce the voltage into the earth with nanosecond response speed, so as to protect the equipment.
