Surge Arrester

Surge Arrester Application range: LDY XA230BC series monitoring synthetic lightning protection device are applied to lightning protection of power, control signal, BNC video signal of monitoring system, with function of characteristics of low clamping voltage, quick response, etc.. which can be used to release and prevent the damage to the protected device arising from inductive lightning from power and control wire or the other surge overvoltage. So they are widely used in the field of security monitoring system, “Global E-eye” system of telecom.(option from standard IEC61643-1, IEC61643-21 and GB50343).Main features: modularization, DIN rail design, convenient for installation and replacement; Build-in temperature control and circuit breaking technology and strong protection ability, high reliability;Green light on in notice window indicates normal, off indicates broken, which is clear and distinguished;Function of multilayer protection: power, power, video signal, control signal;Build in 4mm2 elevating earthing terminal, more reliable earthing.Main technical data: Function modulePowerControl signalBNCNominal Operating voltage Un220V24V12V12VMax. continuous operating Voltage Uc320V36V15V18VVoltage protection level Up<1500kV< 600kV< 80kV< 80kVNominal discharge current In (8/20μs)5kA5 kA5 kA5 kAMax. discharge current Imax (8/20μs)10kA10kAConnection modeWiring terminalWring terminalWring terminalBNCTransmission rate Vs (bit/s)2M16MInsertion loss dB≤ 0.5≤0.5Housing materialEnhanced flame retardant nylon(light gray, flame retardancy degree: V0)Cross-section≥ 3 mm2 stranded/flexible conductor
