PVSPD DC Surge Protector
PVSPD DC surge protection device is applicable to the low-voltage standard IEC EN 50539-11, and is used to protect the DC system and other equipment from overvoltage and instantaneous overvoltage damage. When DC system experiences surge overvoltage due to lightning strikes or other reasons, the protector immediately conducts within nanosecond time, introducing surge overvoltage to the ground, thereby protecting the electrical equipment on the point network. DC surge protection device is a plug-in structure that can be quickly replaced after a 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.
DC Surge protection device are widely used in photovoltaic combiner boxes, power inverters, DC distribution cabinets, etc. It has the advantages of high discharge current, fast response time, and low residual voltage. The maximum photovoltaic voltage reaches UC≤1200VDC.
