Safety of transformers, reactors,power supply units and similar products for supply voltages up to 1100 V - Particular requirements and tests for isolating transformers and power supply units incorporating isolating transformers Ingestion-build-67170 Regulatory authorities recognize the critical1 Scope Replacement: This part of IEC 61558 deals with the safety of isolating transformers for general applications and power supply units incorporating isolating transformers for general applications. Transformers incorporating electronic circuits are also covered by this standard. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here onward, the term transformer covers isolating transformers for
