On December 5, 2016, the Comité Consultivo Nacional de Normalización para la Preservación y Uso Racional de los Recursos Energéticos (CCNNPURRE) published on its official gazette, a project which aims to establish the Mexican Official Norm with the general requirements, testing limits, methods and labeling guidelines for external power supplies. The main purpose of this project is to regulate all aspects regarding External Power Supplies intended to be commercialized, distributed or sell individually or as part of the end product use in the Mexican state.
Takeaways:
• Official Norm will apply for those external power supplies that are used to convert alternating current AC to fixed output levels of direct current DC. It is applicable also for some units with switches that permit to choose manually diverse voltage output levels.
• The maximum power must be 250W, determined physically by design and independent from the product
This norm will be valid 120 days after it’s publication as a definitive and official norm. From that date all power sources must comply with what will be stated in the norm PROY-NOM-029-
