ONCCY Electrical Co., Ltd pioneers in delivering all-encompassing protection solutions within the surge and lightning protection domains, catering to a diverse array of industries. Our EDP Surge Protective Device (SPD) is a remarkable no-fuse, fail-safe surge suppressor, meticulously engineered to conform to the prestigious standards of GB/T18802.1 /EN 61643-11. It accommodates rated voltages of 275V~, 320V~, 385V~, and 420V~, with a maximum discharge current of 10kA. Designed for seamless integration, it is DIN-rail mountable and exhibits a fail-safe self-protected design, compact form, and a formidable 40kA surge capacity.
 

The EDP series surge protective devices stand as paragons of reliability, offering exceptional voltage protection levels and outstanding surge discharge and overload capacities. These devices are quintessential for safeguarding photovoltaic power generation systems against lightning-induced overvoltages. Equipped with a high-energy MOV chip, the EDP series promptly channels excess voltage into the earth at lightning-fast, nanosecond speeds, thereby preserving the integrity of your equipment.

 

Applications and Markets

One of the primary threats to solar panels is the devastation wrought by electrical surges from direct and indirect lightning strikes. The EDP series is indispensable when installed on the DC side, acting as a guardian for terminal devices in photovoltaic systems, such as solar panels and inverters, effectively mitigating the impact of lightning surge currents.

We are a dedicated manufacturer of AC and DC surge protection devices (SPD), boasting a decade of expertise in lighting and surge protection. We offer a 5-year limited warranty alongside OEM/ODM services. Our DC surge protective devices have earned esteemed approvals from TUV, CB, CE, and EAC, in compliance with IEC 61643-31:2018 and EN 50539-11:2013 standards. Elevate your plant's KPIs by safeguarding against power surges with our superior solutions.
