CDN, Immunity | 10 / 150 kHz - 230 MHz
IEC / EN 61000-4-6
NAMUR NE 21
Coupling/decoupling networks (CDN) are used for immunity tests against conducted disturbances induced by high-frequency fields in accordance with IEC / EN 61000-4-6 and Namur. The use of CDNs leads to a high repeatability of the tests and serves to protect additional and auxiliary equipment.
A variety of cable types and connector types as well as matching calibration adapters are available for different areas of application. We also manufacture special models on customer request.
