NOM-029- ENER-2017

Energy Efficiency of External Power Supplies. Limits, Test Methods, Marking, and Labeling.

Applies to external power supplies (EPS), establishes minimum energy efficiency values ​​in operation, and maximum electrical power limits in no-load or empty mode, which are imported, manufactured, marketed, distributed, or supplied for promotional purposes within the country.

They are classified according to:

  • USB output voltage: Nominal output voltage (DC) of 5.0 V ± 0.25 V, with a nominal output current greater than or equal to 500.0 mA DC.
  • Low output voltage: Nominal output voltage less than 6.0 V DC, with a tolerance of ± 5.0%, with a nominal output current greater than or equal to 550.0 mA DC.
  • Generic output voltage: Nominal output voltage greater than or equal to 6.0 V DC, with a maximum output power less than or equal to 250.0 W.
