NOM-029- ENER-2017

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

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

They are classified according to:

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