Mexico Adopts Mandatory Energy Efficiency Standards for External Power Supplies
The Mexican government has established mandatory energy efficiency standards for external power supplies. Slated to enter into force on 25 April 2018, the new regulation sets minimum energy efficiency standards for external power supplies in on-mode, maximum power limits for external power supplies in no-load or vacuum mode, as well as test methods and conformity assessment and marking requirements. It covers external power supplies that convert alternating current voltage to a single level of fixed continuous current voltage with a maximum output power of 250 watts or less. Excluded from the scope are external power supplies incorporating a battery, battery pack or battery type/chemistry switch, as well as supplies that form part of equipment and apparatus that are not sold to the public and are intended for special uses.
