ONCCY is a pioneer in delivering top-tier protection solutions, expertly crafted for a myriad of industries requiring surge and lightning protection. Our EDP Surge Protective Device (SPD) is an innovative surge suppressor that operates without fuses and ensures fail-safe protection. Conforming to GB/T18802.1 and EN 61643-11 standards, it supports rated voltages of 275V~, 320V~, 385V~, 420V~, and handles a formidable discharge current of up to 10kA. Its DIN-rail mountable design boasts a fail-safe, self-protecting feature with a compact build, and is capable of withstanding a powerful surge capacity of 40kA.
The EDP series surge protective devices are engineered to deliver outstanding voltage protection levels and exceptional surge discharge capabilities. Developed for photovoltaic power systems, these devices feature high-energy MOV chips that swiftly redirect any overvoltage caused by lightning or other factors to the earth, ensuring equipment safety with a rapid nanosecond response.
The prime cause of electrical surges damaging solar panels is direct or indirect lightning strikes. The EDP series is specifically designed for DC side installations in PV systems, offering robust protection for terminal devices like solar panels and inverters against deleterious lightning surge currents.
As a seasoned manufacturer with over a decade of expertise in AC and DC surge protection, we offer products with a 5-year warranty and comprehensive OEM/ODM services. Our DC surge protective devices are TUV, CB, CE, and EAC certified, adhering to IEC 61643-31:2018 and EN 50539-11:2013 standards, enhancing your plant's KPIs through superior power surge protection.
