Surge Reduction Filter

Surge Reduction Filter Application range: LDY-C/X series surge protective device for control signal are applied to the front side of the control signal system equipment, providing protection against overvoltage arising from surge to the control signal wire or misoperation. (Option from standard IEC61643-21 and GB50343).Main features: High current capacity, low residual voltage;Introducing multilayer protection technology, strong protection ability, high reliability;Build-in earthing terminal, strong wiring ability, more reliable grounding;Modularization design, wiring terminal connection, convenient for installation and replacement;Protect two pairs of data line meanwhile, and space saving.Main technical data: TypeLDY-C/X5LDY-C/X12LDY-C/X24LDY-C/X48Rated working voltage Un V5V12V24V48VMax. continuous operating Voltage Uc8V18V36V75VVoltage protection level Up< 50V< 50V< 80V< 150VPart No.085401085402085403085404Nominal discharge current In (8/20μs)5 kAWiring modeWiring terminalTransmission rate Vs (bit/s)2MInsertion loss dB≤0.3Enclosure materialEnhanced flame retardant nylon(light gray, flame retardancy degree: V0)Installation method35mm standard DIN rail installmentCross-sectional area≥ 1 mm2 stranded/flexible conductor Installation instruction: 1. The protector connected in serial between the signal channel and the protected device;2. Connect the input terminal to the signal channel, and the output terminal to the protected device, reverse connection prohibited;3. Connect the earthing wire of the protector to the equalizing ring of the lightning protection system;4. Invalid system the earthing short circuit or open circuit.
