DC Surge Protection 40kA 2P 500VDC With Indicator AUX

• DQSA-PV-COM-C40 series of DC Surge Protective Device (SPD) for use in Photovoltaic applications. Surge protective devices provide protection from lightning current and over-voltage surges insystem from 48VDC to 1000Vdc.
• Providing power with photovoltaic solar panels is interesting in the context of renewableenergysources, 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 photovoltaicsystems (PV), lightning strikes are a major components in the risk to be assumed, both for thedirecteffect of lightning on the structures, and of the surge over-voltages on the installation.
• Cells are generally associated with inverters. We have developed a specific Din Rail product to protect DC end of cells and inverters against surge in power plant or residential application. 
• With the MOV(Metal Oxside Varistor), the over-voltage will be limited at the value of thevoltageprotection level of the DQSA-PV-COM-C40 surge protector.
• Our surge protector, as recommendedinstandards and guides, insure all protections (between +and-, + and Ground,-and Ground).
• On each surge arrest-er, as option, an available auxiliary contact will inform the end life status to ensure a maximum efficiency.
