VM-TDRDATA/SIGNAL LINES PROTECTIONIEC category / EN type: C1/C2/C3 (IEC 61643-21)Design:Replaceable plug-in moduleNumber of protected pairs: 1 (2 lines)Coarse Protection:3 terminal GDTNom. Operating Voltage U n:110VDCMax. Operating Voltage U c:170VDCSeries Resistance: 9 - 11ΩFreq:< 16 MHzSurge Discharge Ratings: I n: 10kA 8/20µs, I max: 20kA 8/20µsSeries load current:300mASafety:Internal thermal runaway disconnectorIndication:1x end-of-life status flagEnclosure:DIN 43880 1TE, DIN rail mountTerminals:Multi-strand to 6 mm 2The VM-TDR series has been developed as a generic protector for use on data transmission circuits.Coarse protection is provided by a three terminal gas discharge tube.Internal thermal disconnectors are used to reduce the hazards of thermal runaway during fault conditions, or ifmains incursion onto the low voltage data circuit, occurs.Technical characteristicsTypeProtection constructionNumber of protected pairsNominal operating voltageMax. continuous operating voltageRated spark overvoltageUnUc(a/b-PG)(a-b)Rated operating current at 25oCI LNominal discharge current (8/20µs) I nMax. discharge current (8/20µs) ImaxResidual voltage at 5 kA (8/20µs)Response time of overvoltage protection t AThermal protectionInsulation resistance of the protectionSerial resistance RTransverse capacitance CLimit frequency f GTerminal cross sectionOperating temperatureDegree of protectionHousing materialDimensions DIN 43880Mounting EN 60715Ordering code Base + Replaceable plug-in moduleReplaceable plug-in moduleVM-TDR110VTwo parts: base + replaceable plug-in module1 (2 conductors)110V DC170V DC184V - 276V184V - 550V300mA10kA20kA< 500V< 100 nsThermal disconnection in lines a and b≥ 1GΩ9 - 11Ω10 pF16 MHzMulti-strand to 6 mm 2-40oC … +80oCIP 20Thermoplastic; yellow, extinguishing degree V-O1TEOn a 35mm DIN rail703 052703 051Dimensional drawingsConnection diagram68904517.5Legend:TDGDTRPGthermal decouplergas discharge tuberesistorprotective groundingPGbaTDGDTTDRRbase,b,awww.iskrazascite.si31
