Sicherheit von Transformatoren,Netzgeraeten,Drosseln und dergleichen. EMV-Anforderungen Power transformers,power supply units,reactors and similar products EMC requirements Transformateurs,blocs d'alimentation,bobines d'inductance et produits analogues. Prescriptions CEM Remains Current
适用范围:This international product family standard applies to independent transformers, reactors and power supply units covered by IEC 60989 and the IEC 61558 series of standards. It prescribes the electromagnetic compatibility requirements for emission and immunity in the frequency range 0 Hz to 1 000 MHz. Transformers, reactors and power supply units delivered with or incorporated in an appliance or equipment shall comply with the relevant EMC standard applicable to that appliance or equipment. However this standard may be used as a guide to test the transformers, reactors and power supply units separately before incorporating them in the appliance or equipment. This EMC standard covers only performance. Abnormal operation of the transformer, reactor and power supply unit (e.g. simulated faults in the electric circuitry for testing purposes or functional safety by influence of electromagnetic phenomena) are not taken into consideration in this standard. NOTE When the term transformer is used, it covers transformers, reactors and power supplies where applicable. This standard does not apply to: - motor-generator sets; - uninterruptible power supplies (UPS) covered by IEC 62040; - power supply units covered by IEC 61204, (i.e. DC-DC converters, DC power and distribution equipment and power supply units for use in applications covered by IEC 60950, IEC 61010-1, IEC 60601-1 and IEC 60065); - step-down converters covered by IEC61347-1 and 61347-2-2; - power supplies and converters for use with or in products covered by IEC 61347-2-2.
