BS EN IEC 62041:2020 pdf free.Transformers, power supplies, reactors and similar products – EMC requirements.
BS EN IEC 62041 This document is applicable to transformers, reactors and power supply units covered by the IEC 61558 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.If the apparatus is part of a system, or can be connected to auxiliary apparatus, the apparatus shall be tested while connected to the minimum representative configuration of auxiliary apparatus necessary to exercise the ports in a similar manner to that described in CISPR 32. In cases where manufacturer’ s specification requires external filtering and/or shielding devices or measures that are clearly specified in the user’s manual, the measurement requirements of this document shall be applied with the specified devices or measures in place.BS EN IEC 62041 pdf download.
