Fisher Telcom Surge CDN
Surge Coupling-Decoupling Networks (SCDN) are used to couple the surge specified in IEC 61000-4-5 onto active telecom lines to determine if the telecom equipment sustains functional upset or damage due to the surge. The Surge CDN maintains all of its Technical Specifications while delivering the full range of open circuit voltage to short circuit current demanded by the EUT load.
