Product Description
YCS8 Photovoltaic DC Surge Protective Device
 |  | General YCS8-series is applicable to photovoltaic power generation system. When surge overvoltage occurs in the system due to lightning stroke or other reasons The protector immediately conducts in nanosecond time to introduce the surge overvoltage to the earth, thus protecting the electrical equipment on the grid. Features T2/T1+T2 surge protection has two types of protection, which can can meet Class I (10/350 μS waveform) and Class II (8/20 μS waveform) SPD test, and voltage protection level Up ≤ 1.5kV; Modular, large-capacity SPD, maximum discharge current Imax=40kA; Pluggable module; Based on zinc oxide technology, it has no power frequency aftercurrent and fast response speed, up to 25ns; The green window indicates normal, and the red indicates a defect, and the module needs to be replaced; Dual thermal disconnection device provides more reliable protection; Remote signal contacts are optional; Its surge protection range can be from power system to terminal equipment; It is applicable to direct lightning protection and surge protection of DC systems such as PV combiner box and PV distribution cabinet |
