Scope of application
The MGSPD series C-class surge protector is suitable for photovoltaic power generation systems. When a surge overvoltage occurs in the system due to lightning or other reasons, the protector immediately conducts within nanoseconds, introducing the surge overvoltage to the ground and protecting the electrical equipment on the grid. The PJ SPD series adopts a plug-in structure, which can be quickly replaced after module failure; After the lightning protection module fails, the color of the indicator window changes from green to red, and an alarm signal is sent to the remote alarm device connected to the remote signal terminal of the product.
