EM Test CNV 504N1.3

Description

EM Test CNV504N1.3 coupling/decoupling networks for unshielded  unsymmetrical interconnection signal/data lines. Surge pulses or Ringwave pulses are applied to unshielded unsymmetrical interconnected lines by means of standalone coupling/decoupling networks for 4 signal/data lines. CNV 504 N1.3 combines three different applications; coupling of Surge pulse via capacitor or gas arrestor and coupling of Ringwave pulses via capacitor being required by EN IEC 61000-4-5 and/or EN IEC 61000-4-12.

The required coupling mode, Differential or Common, can easily be selected by means of a simple jumper. In accordance with EN IEC 61000-4-5 and EN IEC 61000-4-12 pulses are coupled via different coupling elements such as capacitors or gas arrestors depending on the characteristics of the line signals.

The EM TEST CNV 504N/508N series of coupling decoupling networks are multifunctional CNVs for the application of Surge and Ringwave pulses onto signal/data lines.

The standard CNV 504N/508N models combine three different applications; coupling of Surge pulse via capacitor or gas arrestor and coupling of Ringwave pulses via capacitor being required by the relevant standards. The required coupling mode can easily be selected by means of a simple jumper.

The CNVs also include the required decoupling part consisting of decoupling inductors of 20mH for each line. To protect the auxiliary equipment being needed for testing the DUT an additional protection circuit is integrated at the signal/data line input.

EM TEST offers CNV 504N/CNV 508N coupling/decoupling networks for various test voltages up to 10kV and for higher signal voltages/currents (up to 600V and up to 4A). Dedicated CNVs are available e.g. for railway applications as per EN 50155 and for other customer specific test
