1500VDC PV DC Surge Protection Device

  • No need to consider the load current, plug design, can be replaced live, easy to maintain.
  • Internal steal temperature control circuit breaker technology, high safety performance, no freewheeling.
  • Green indicates normal, red indicates fault, prompt replacement, clear and easy to distinguish.
  • Remote monitoring interface (dry contact) is provided to realize remote monitoring of working status.


HCSPD1 series surge protectors belong to the DC side lightning arrester of the T2 PV system. When the system has overvoltage due to a lightning strike or other reasons, the protector immediately turns on in nanoseconds to introduce the overvoltage into the earth for discharge, so as to protect the equipment on the power grid.

They have reliable voltage protection levels, super surge discharge capacity and safety overload capacity, which are used for lightning protection of photovoltaic power generation systems.

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.
