VMS-TC SeriesDATA/SIGNAL LINES PROTECTIONIEC category / EN type: C1/C2/C3 (IEC 61643-21)Design: Replaceable plug-in moduleMode of protection:Longitudinal, TransverseCoarse Protection: 3 terminal GDTAvailable voltages: 5, 12, 15, 24, 30, 48, 60 V DC, 110VACFreq: 0.6 - 3 MHz (see specification sheet)Surge Discharge Ratings: I n: 10kA 8/20 µs, I max: 20kA 8/20µsSeries load current:1AEnclosure:DIN 43880 1TE, DIN rail mountTerminals:Multi-strand to 6 mm 2The VMS-TC series of low voltage protective devices has been developed to protect against the effects of inducedvoltages onto data, signal and communication circuits.It is intended for those applications where high ground potential rises may frequently occur, such as in locationsclose to electric railways.The circuit topology consists of a multi-stage protector providing both common (longitudinal) mode and differential(transverse) mode protection.Coarse protection is provided by a three terminal gas discharge tube while fine protection is provided using a highspeed silicon avalanche diodes or metal oxide varistor stage. Care is taken to ensure coordination between thesetwo stages without voltage or surge current blind spots occurring.Thermal protection is provided to reduce the hazards of thermal runaway should there be an inadvertent mainsincursion fault.Both common (longitudinal) mode and differential (transverse) mode protection is provided.Technical characteristicsTypeProtection constructionNumber of protected pairsNominal operating voltageMax. continuous operating voltageRated spark overvoltageU c(a/b-PG)(a-b)Rated operating current at 25oCNominal discharge current (8/20µs)Max. discharge current (8/20µs)Residual voltage at 5 kA (8/20µs)I LI nI max(line-line)Response time of overvoltage protection t A (a-b)Response time of overvoltage protection t A (a/b-PG)Insulation resistance of the protectionU n(a-b)(a/b-PG)Serial resistance RTransverse capacitance C (a-b)(a/b-PG)Limit frequency f GTerminal cross sectionOperating temperatureDegree of protectionHousing materialDimensions DIN 43880Mounting EN 60715Ordering code Base + Replaceable plug-in moduleReplaceable plug-in module5V5V DC7V DC280 - 500V6.5 - 9V1A10kA20kA< 20V< 1ns100ns≥ 6K Ωca 1Ω5nF8pF0.6MHz702 005702 00412V12V DC15V DC280 - 500V6.5 - 9V1A10kA20kA< 39V< 1ns100ns≥ 15M Ωca 1Ω3nF8pF0.9MHz702 008702 007VMS-TC15V 24V 30V 48VTwo parts: base + replaceable plug-in module1 (2 conductors)15V DC18V DC280 - 500V6.5 - 9V1A10kA20kA< 45V< 1ns100ns≥ 18M Ω702 011702 01024V DC28V DC280 - 500V6.5 - 9V1A10kA20kA< 65V< 1ns100ns≥ 28MΩ702 014702 01330V DC33V DC280 - 500V6.5 - 9V1A10kA20kA< 77V< 1ns100ns≥ 33M Ω702 017702 01648V DC52V DC280 - 500V6.5 - 9V1A10kA20kA< 135V< 1ns100ns≥ 52M Ω> 1G Ω / 100Vca 1Ω2.2nF8pF1.1MHzca 1Ω1.9nF8pF1.4MHzca 1Ω1.4nF8pF1.8MHzca 1Ω0.82nF8pF2.2MHzMulti-strand to 6 mm2- 40oC ... + 80oCIP 20Thermoplastic; yellow, extinguishing degree V-O1TEon a 35mm DIN rail702 020702 01960V60V DC64V DC280 - 500V6.5 - 9V1A10kA20kA< 150V< 1ns100ns≥ 64MΩca 1Ω0.7nF8pF3.0MHz702 023702 022110 V110V DC170V DC400 - 680V16 - 20V1A10kA20kA< 450V< 25ns100ns≥ 170MΩca 1Ω90pF8pF10Mhz702 002702 001www.iskrazascite.si25
