CN 200N Series - Single-box transformer assembly for LF conducted immunity testing The CN 200N Series is a standalone coupling network unifying up to three audio transformers, each with 100 A capacity, being configurable for various test requirements (e.g. LV 123, ISO/TS 7637-4 draft). The CN 200N Series is used to apply the test signals to the lines under test via an audio transformer to perform ripple voltage tests and continuous or transient conducted immunity tests.
