Safety of transformers, reactors, power supply units and combinations thereof - Part 2-12: Particular requirements and tests for constant voltage transformers and power supply units for constant voltage
This part of IEC 61558 deals with the safety of constant voltage transformers for general applications and power supply units incorporating constant voltage transformers for general applications. Constant voltage 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 constant voltagetransformers for general applications and power supply units incorporating constant voltagetransformers for general applications.NOTE 2 Switch mode power supply units are covered by IEC 61558-2-16.This Part 2-12 is
