DESCRIPTION
CSN EN IEC 61643-352
CSN EN IEC 61643-352 This part of IEC 61643 covers the application of surge isolation transformers (SITs) that are used in tele-communication transformer applications with signal levels up to 400 V peak to peak. These transformers have a high rated impulse voltage with or without screen between the input and output windings. SITs are components for surge protection and are used to mitigate the onward propagation of common-mode voltage surges. This document describes SITs' selection, application principles and related information. This document does not cover power line communication transformers. Original English text of CSN EN Standard. The price of the Standard included all amendments and correcturs.
