Low-voltage switch mode power supplies. Part 3: Electromagnetic compatibility (EMC) (IEC 61204-3:2016)

Alkalmazási terület

1.1.1 Equipment covered by this document This part of IEC 61204 specifies the electromagnetic compatibility (EMC) requirements for switch mode power supply (SMPS) units supplied by source voltages up to 1 000 V AC or 1 500 V DC providing AC and/or DC output(s), except inverter output(s) establishing AC mains (see exceptions under 1.1.3.) NOTE 1 This document by definition covers DC/DC converters. NOTE 2 Power supplies can provide accessory AC mains socket outlets, when such outputs are supplied from the AC mains. NOTE 3 Ringing generators used in telecoms applications are covered by this document. This product standard covers both stand alone and component power supply (PSU) units as defined in this document. It covers PSU units for use in or with IT equipment normally covered by IEC 60950-1 and/or IEC 62368-1; PSU units for use in or with measurement, control and laboratory equipment normally covered by IEC 61010-1; PSU units for use in or with medical equipment – normally covered by IEC 60601-1; PSU units for use in or with audio, video and similar electronic apparatus – normally covered by IEC 60065 and/or IEC 62368-1. It also covers DC power and distribution equipment and DC/DC converters. Where no standard exist, use of this document for other applications is not precluded. 1.1.2 Additional requirements Requirements additional to those specified in this document may be necessary for • PSUs intended for operation in special environments (for example, extremes of temperature; excessive dust, moisture or vibration; flammable gases; and corrosive or explosive atmospheres); • PSUs intended to be used in vehicles, on board ships or aircraft, or in tropical countries; • PSUs intended for use where ingress of water is possible. NOTE Attention is drawn to the fact that authorities in some countries impose additional requirements for health, environmental and similar reasons. 1.1.3 Exclusions This document does not apply to • motor-generator sets; • uninterruptible power supplies (UPS) to IEC 62040-1; • PSUs covered by IEC 61558-1 (i.e. power supply units incorporating safety isolating transformers providing SELV or PELV output(s) in accordance with IEC 60364-4-41) and PSUs for use with household and other consumer products, except those covered by IEC 60065 and IEC 60950-1 and/or IEC 62368-1; • transformers covered by IEC 61558-1; • step-down converters covered by IEC 60146-1-1; • PSUs and converters intended for DC supplied bulb lamps, halogen lamps or LED lamps covered by CISPR 15. 1.1.4 Types of power supply Two types of power supplies are covered by this document: a) stand alone (or end-product) power supplies Power supplies intended for free-standing operation (individual apparatus). This part of IEC 61204 is applicable to PSUs developed as a unit with a direct function and sold on the market as a stand alone unit. b) component power supplies These can be divided into two categories: 1) component power supplies considered as equivalent to stand alone power supplies (apparatus) This part of IEC 61204 is applicable to this category of component PSUs. These PSUs are considered to be apparatus with respect to their EMC requirements, for example those PSUs intended for use in installations or sold to the general public, cases where no further EMC tests are anticipated. This does not include PSUs sold as spares for repair which have been tested as part of an overall equipment. 2) component power supplies intended for a professional installer This part of IEC 61204 is applicable to this category of power supplies only as an aid to specify relevant EMC requirements in order that various end-product standards may be met. These are component power supplies that are intended for incorporation into a final product by a professional installer. These products may be sold to a professional installer or placed on the market for specialized distribution and use. Further EMC tests of the assembly are assumed. 1.1.5 Configurations and combinations of power supplies
