ONCCY offers comprehensive protection solutions in the fields of surge protection, lightning protection/earthing for many different industries.EDP Surge Protective Device (SPD) is a no-fuse, fail-safe surge suppressor featuring. Complying standard GB/T18802.1 /EN 61643-11, Rated voltage 275V~,320V~,385V~, 420V~, Maximum discharge current 10kA, it is DIN-rail mountable featuring a fail-safe self-protected design, visual indicator, small footprint, and 40kA surge capacity.
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.
