Product Description
DC Surge Protective Device (SPD) is designed to protect photovoltaic (PV) systems against lightning-induced surges and transient over-voltage. It safely diverts surge current to ground, preventing damage to sensitive DC equipment and improving system reliability.
The device adopts a compact modular design for DIN rail installation and features a visual status window for easy operation monitoring. When the indicator turns red, the module can be replaced quickly without removing the base, reducing maintenance time and cost.
With high discharge capacity and fast response time, this DC SPD is widely used in PV combiner boxes, inverters, DC distribution boards, and solar power systems. It complies with IEC 61643-31 standards and is suitable for residential, commercial, and industrial photovoltaic applications
