4.1.1. Coupling Surge and Ringwave
The coupling networks of the CDN 117A seriesare suitable for tests according the following standards:
IEC 61000-4-5 Surge impulse with combination generator 1.2/50 µs / 8/20 µs
The
GTD is line voltage related (90 V type) and inside the bridge located. Other line voltages may require an GTD
with adapted line voltage. For more information see 4.2.2. Coupling with 40 Ohm and Gas Discharge Tube (GDT)
