Scope of application
SUP4 series C-level surge arrester protectors are suitable for photovoltaic power generation systems. When a surge overvoltage occurs in the system due to lightning strikes or other reasons.
The protector immediately turns on quickly within nanoseconds，introducing the surge overvoltage into the ground, thereby Protect the electrical equipment on the dot network.
The SUP4 series has a plug-in structure, which can be quickly replaced after the module fails: When the lightning protection module fails, the color of the indicator window changes from green to red, and at the same time, an alarm signal is sent to the remote alarm device connected to the product’s remote signaling terminal.
Application Environment
- The normal range of ambient air temperature is not higher than + 40℃ , not lower than-25 ℃, and the relative humidity is not greater than 95% ;
- The altitude of the installation site shall not exceed 2000 meters;
- Pollution level 3 ;
- There is no explosion hazard medium , and there is no gas and dust( including conductive dust ) in the medium which will be corrode metals and destroy insulation.
