HS25-C40-PV series of DC Surge Protective Device (SPD) for use in Photovoltaic applications. surge protective devices provide protection from lightning current and overvoltage surges in system from 500Vdc to 1500Vdc.

Providing power with photovoltaic solar panels is tremendously interesting in the context of renewable energy sources, as regards economical photovoltaic systems connected to the public electricity network. Because of their exposition, frequently in isolated sites and of the extended surface of photovoltaic systems (PV), lightning strikes are a major components in the risk to be assumed, both for the direct effect of lightning on the structures, and of the surge overvoltages on the installation.

Cells are generally associated with inverters. CUAJE® has developed a specifc Din

Rail product to protect DC side of cells and inverters against surge in power plant or residential application.

With the MOV (Metal Oxside Varistor), the overvoltage will be limited at the value of the voltage protection level of the OBV5-C40-PV DC surge protector. Our surge protector, as recommended in standards and guides, insure all protections (between + and-, + and Ground, – and Ground). On each surge arrester, as option, an available auxiliary contact will inform the end life status to ensure a maximum effciency.
