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.
Coupling Modes:
  • 0.5uF/40ohm for signal/data lines, I/O ports and auxiliary AC power ports
  • 0.5uF/40ohm for DC power ports
  • 9uF/10ohm for AC/DC power ports (L/N-PE)
  • 18uF for AC/DC power ports (L/N)
