The International Electrotechnical Commission (IEC) has published IEC 61558-2-10 ed1., “Safety of Transformers, Reactors, Power Supply Units and Combinations Thereof – Part 2-10: Particular Requirements and Tests for Separating Transformers with High Insulation Level and Separating Transformers with Outpit Voltages Exceeding 1,000V.” The standard is available in the IEC’s webstore here.
“IEC 61558-2-10:2014 deals with the safety of separating transformers with high insulation level and separating transformers with output voltages exceeding 1 000 V. Transformers incorporating electronic circuits are also covered by this standard. This first edition cancels and replaces Chapter ll Section Three of IEC 60989 published in 1991. It constitutes a technical revision.”
“The main changes consist of:
- updating this part in accordance with IEC 61558-1:2005, and
- adding power supply units to the scope.”
