eft/burst coupling network
High frequency pulse signals can result in cross-talk between conductors running in parallel even over
short distances. This behavior is taken into account in the latest and currently valid edition of the EFT/
burst standard IEC/EN 61000-4-4 (2004). Only the single coupling mode of „all conductors together against
reference ground“ is called for in interference immunity measurements with fast transients.
3-phase coupling network
For AC and DC up to 100 A per
channel
Short-term overstress capability
Easy handling
Secure and durable construction
Compatible with all types and
brands of EFT/burst generators
This simplies the construction and utilization of coupling networks considerably, complicated coupling
switches can be omitted.
The CDN 163 is a 3-phase EFT/burst pulse coupling network for large EUT currents. Although designed
for continuous duty at up to 100 A per phase, the unit can be subjected to considerably higher currents
for short durations. For 1-phase or DC applications it‘s possible to connect the input channels parallel,
thus to increase the EUT current. As a result, high inrush currents or pulse-shaped peak currents can
be handled with ease. The current limitation is largely down to a matter of thermal loading. A built-in
thermometer enables the heating effect to be monitored. The type of construction, using a metal housing
for use directly on the ground reference plane, ensures excellent HF earthing. The power and EUT con-
nections take the form of generously dimensioned screw terminals.
