EDP 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.


Product Benefits

  • 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.
