BS EN IEC-62041-2020 pdf download.Transformers, power supplies, reactors and similar products — EMC requirements.
This document is applicable to transformers, reactors and power supply units covered by the
IEC 61 558 series of standards. This document deals with the electromagnetic compatibility requirements for emission and immunity within the frequency range 0 Hz to 400 GHz. No tests need to be performed at frequencies where no requirements are specified.
For associated transformers, associated reactors and associated power supply units either supplied with or incorporated into an appliance or equipment, the relevant EMC standard for that appliance or equipment applies.
This document covers normal operating conditions only. Other operations of the transformers, reactors and power supply units (e.g. simulated faults in the electric circuitry for testing purposes or functional safety due to the effects of the electromagnetic phenomena, or evaluation of human being for exposure to electromagnetic fields (EMF)) have not been taken into consideration in this document.
Requirements are specified for each port considered. If requirements are different, the most severe takes precedence.
This document may also be used as a guide to test transformers, reactors and power supply units separately before these are incorporated into an appliance or equipment.
NOTE When EUT (Equipment under test) is used, it covers transformers, reactors and power supply units where applicable.
This document does not apply to:
• uninterruptible power supplies (UPS) covered by IEC 62040 (all parts);
• power supply units covered by IEC 61 204, (i.e. DC-DC converters, DC power and distribution equipment and power supply units for use in applications covered by IEC 60950-1 , IEC 61 01 0-1 , IEC 60601 -1 and IEC 60065);
• power supplies and converters for use with or in products covered by IEC 61 347 (all parts).
