Scope of application
UP4 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.
