CNV 504N/508N - Coupling/decoupling networks for signal/data lines
Surge pulses or Ring wave pulses are applied to unshielded unsymmetrical interconnection lines (signal/data lines) by coupling/decoupling networks. For such testing, EMTEST offers CNV series for either 4 or 8 signal/data lines.
Complied withEN/IEC 61000-4-5 and EN/IEC61000-4-12, the pulses are coupled by different coupling elements such as capacitors or resistors depending on the characteristics of line signals.
Coupling/decoupling networks as perEN/IEC 61000-4-5 and EN/IEC 61000-4-12
Coupling with 0.5 µF capacitor for Surge (3.3 µF capacitor for Ringwave)
20 mH decoupling inductor per line
Selectable Differential/Common mode
Test voltage up to 4 kV, 7 kV and 10 kV
Line voltage 50 V (higher voltages on request)
Line current 1 A (higher current values on request)
BenefitsCNV 504N/508N series - Multifunctional coupling/decoupling networks
The series of EMTEST CNV 504N/508N are multifunctional coupling decoupling networks for the application of Surge and Ringwave pulses onto signal/data lines.
The standard CNV 504N/508N models combine three different applications; the required coupling mode can be easily selected by means of jump line.
The CNV 504N/508N series consist of decoupling inductors of 20mH for each line. To further protect, an additional protection circuit is integrated at the signal/data line input.
EMTEST 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 applications.
