They must ensure safe electrical separation and comply with the statutory requirements in terms of EMC. Power supplies must also be able to withstand extreme conditions and be immune against external interference, as well as protecting connected appliances, such as sensitive electronic modules.<\/p>\n<p>When developing the first generation of MGV switch-mode power supplies between 1981 and 1983, control of emission and immission was a major issue, even long before EMC legislation and CE conformity came into force. Today we ensure that our power supplies offer especially high resistance and are equipped for daily use by incorporating certain immission values that are in some cases far above required standards.<\/p>\n<\/div><\/section><\/div><div  class='hr av-t19qe-80f58921454e74badb3d411dcb453eb2 hr-default  avia-builder-el-6  el_after_av_one_full  el_before_av_one_full '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div><\/p>\n<div class='flex_column_table av-kycqm-df2ac0a9d1b458b2a8837f0c2af06e79 sc-av_one_full av-equal-height-column-flextable'>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-kycqm-df2ac0a9d1b458b2a8837f0c2af06e79\">\n.flex_column.av-kycqm-df2ac0a9d1b458b2a8837f0c2af06e79{\n-webkit-border-radius:0px 0px 0px 0px;\n-moz-border-radius:0px 0px 0px 0px;\nborder-radius:0px 0px 0px 0px;\npadding:25px 25px 25px 25px;\nbackground-color:#f2f8f6;\n}\n<\/style>\n<div class='flex_column av-kycqm-df2ac0a9d1b458b2a8837f0c2af06e79 av_one_full  avia-builder-el-7  el_after_av_hr  el_before_av_hr  first flex_column_table_cell av-equal-height-column av-align-top '     ><p>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-jnegtikq-20ea269f4d9a3e29bc685a251f40cab7\">\n#top .av_textblock_section.av-jnegtikq-20ea269f4d9a3e29bc685a251f40cab7 .avia_textblock{\ncolor:#017655;\n}\n<\/style>\n<section  class='av_textblock_section av-jnegtikq-20ea269f4d9a3e29bc685a251f40cab7'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock av_inherit_color'  itemprop=\"text\" >\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-88lku-5f9c10e7086d37943cd2388df9b695a0\">\n.av_font_icon.av-88lku-5f9c10e7086d37943cd2388df9b695a0 .av-icon-char{\nfont-size:20px;\nline-height:20px;\n}\n<\/style>\n<span  class='av_font_icon av-88lku-5f9c10e7086d37943cd2388df9b695a0 avia_animate_when_visible av-icon-style- avia-icon-pos-left av-no-color avia-icon-animate'><span class='av-icon-char' aria-hidden='true' data-av_icon='\ue812' data-av_iconfont='entypo-fontello' ><\/span><\/span>\n<p><strong>Tested in our own EMC laboratory<\/strong><\/p>\n<\/div><\/section><br \/>\n<section  class='av_textblock_section av-jnegtikq-9db2f7daf6df9d2e9c0bd6205c16c434'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>For many years, we have been testing the electromagnetic compatibility of both our power supplies and DC\/DC converters in our own laboratory.
