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.
