BS EN IEC 61204-7:2018

This standard BS EN IEC 61204-7:2018 Low-voltage switch mode power supplies is classified in these ICS categories:

• 29.200 Rectifiers. Converters. Stabilized power supply

IEC 61204-7:2016 is available as IEC 61204-7:2016 EXV which includes the provisions of the general rules dealt with in IEC 62477-1:2012.

IEC 61204-7:2016 specifies the safety 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. This product standard covers both stand-alone and component SMPS as defined in this document. DC power and distribution equipment which provides, distributes, monitors, and controls isolated secondary circuit power to other equipment typically used in information and communication technology equipment installations. This edition includes the following significant technical changes with respect to the previous edition:
a) use of IEC 62477-1 as reference document, instead of IEC 60950-1;
b) modification of the title by deleting the wording "DC output-" and adding "switch mode".
