NOM-029-ENER-2017: Energy efficiency of external power supplies. Limits, Test Methods, Marking and Labeling

Last updated: 8 August 2019

This standard sets the minimum energy efficiency levels of external power supplies in operation, the maximum limits of electrical power in non-load or vacuum mode. They are classified according to:

  1. the USB output voltage;
  2. low output voltage; and
  3. generic output voltage. See the attachment for the minimum energy efficiency levels.
