14、9-03-01. This European Standard supersedes EN 61558-2-4:1997. The main changes consist of updating this part in accordance with EN 61558-1:2005, and increasing the supply voltages up to 1 100 V to be in line with the standards of TC 14. This part is intended to be used in conjunction with the latest
15、 edition of EN 61558-1 and its amendments. It is based on EN 61558-1:2005. This part supplements or modifies the corresponding clauses in EN 61558-1, so as to convert that publication into the European Standard: Particular requirements and tests for isolating transformers and power supply units inco
16、rporating isolating transformers. Where a particular subclause of Part 1 is not mentioned in this part, that subclause applies as far as is reasonable. Where this part states “addition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. The following dates we
