Electromagnetic compatibility (EMC Directive) governs the electromagnetic emissions of equipment in order to ensure that it does not disturb radio, telecommunications and other equipment. The directive also governs the immunity or susceptibility of the equipment to interference from radio emissions normally present, when used as intended.
There are various standards set out under this directive to standardise product safety and performance by intended application. The base of the EMC Directive is 89/336/EEC, this has been modified by Directive 92/31/EEC, 93/68/EEC & 91/263/EEC. Repealed Directives include 76/889/EEC and 76/890/EEC. EMC Directive 89/336/EEC will be repealed by the new 2004/108 EC Directive in July 2007.

You must ensure that you select the appropriate power supply based on the EMC standard that it is designed to as different equipment require varying degrees of electromagnetic emission and immunity protection.
