Mexico’s NOM-029-ENER-2017 published in October 2017 became effective on April 25, 2018. All external power supplies require this certification, which is obtained through test evaluation. The NOM-029-ENER-2017 is applicable for all power supplies intended to convert electrical voltage from alternating current (AC) to a single level of voltage or direct current (DC), and with a maximum output power that is less or equal to 250W.
In addition, power supplies that allow switching to manual output voltage levels, independent from the product, also require testing and certification. There are a few exceptions depending on characteristics of the power supplies which the NOM-029-ENER-2017 is not applicable.
Furthermore, when approving your electronic device under NOM-019-SCFI-1997 or NOM-001-SCFI-1993, its power supply will not require this additional certification.
Please contact LARCG for more information regarding the timeline of these and other requirements in Mexico, Latin America and Caribbean countries.
