Safety of transformers,reactors,power supply units and combinations thereof. EMC requirements
适用范围：This international product family standard applies to transformers, reactors, power supplyunits and combinations thereof covered by the IEC 61558 series of standards. This standarddeals with the electromagnetic compatibility requirements for emission and immunity within thefrequency range 0 Hz - 400 GHz. No measurement needs to be performed at frequencieswhere no requirement is specified.Transformers, reactors, power supply units and combinations thereof delivered with orincorporated in an appliance or equipment should follow the relevant EMC standard applicableto that appliance or equipment. However, this standard may be used as a guide to test thetransformers, reactors, power supply units and combinations thereof separately beforeincorporating them in the appliance or equipment.This EMC standard covers performance only. Other operations of the transformers, reactorsand power supply units (e.g. simulated faults in the electric circuitry for testing purposes orfunctional safety due to the effects of the electromagnetic phenomena, or evaluation of humanbeing for exposure to electromagnetic fields (EMF)) have not been taken into consideration inthis standard.This standard does not apply to:– uninterruptible power supplies (UPS) covered by IEC 62040 series;– power supply units covered by IEC 61204-3,(i.e. DC-DC converters, DC power and distribution equipment and power supply units foruse in applications covered by IEC 60950-1, IEC 61010-1, IEC 60601-1, IEC 60065 and IEC62368-1);– power supplies and converters for use with or in products covered by IEC 61347-1.
