Instruction sheet LEIK RJ45-POE SPD base on IEC and ITU-T standard,apply to multi-protection of electric circuit,LK RJ45 Signal SPD adopt aluminum alloy as the shell material. It can work stable under the severe environment. And it is with the advantage of easy installation, dustproof, anti-corrosion, and good appearance. This signal SPD is suitable for the POE power supply High Definition Digital Security Camera, POE power supply Exchanger and Concentrator. This product can prevent the equipment from the permanent damage or wink out caused by induced over-voltage, over current, and other induced surge voltage. LK signal SPD is combined with Intelligent Line Adapter (ILA). When the SPD is used in the POE system, it can automatically discriminate the idle line power supply from the data line power supply, so that it suitable for any kinds of POE power supplies system Product typeTypeLK-RJ45/8-POESignalpowerRated working voltageUn5V48VMaximum continuous voltageUc5.8V72VNominal discharge current(8/20μs)Line/lineIn3KA3KAline/ground3KA3KAMaximum discharge current (8/20μs)Imax5KAProtection of voltage level(@In)line/line≤80V≤200Vline/ground≤80V≤200VTransmission rate (3dB)fg>100MHz--InterfaceRJ45 interfaceProtection line1,2,3,64,5(+) 7,8(-) Shell materialAluminum alloyInsert losslL≤0.5dB/Series resistanceR4.7Ω/
