How is the on-mode power measured in case of an external power supply?

The Regulation describes the measurement of the on-mode power in Annex IIIa Point 1.2.7.

The on-mode power must be measured at the AC input in the following cases:

  • displays with an internal power supply,
  • displays with an EPS of any kind packaged (bundled) with the device,
  • displays with an unbundled but non-USB EPS.

The on-mode power must be measured at the DC input for displays with an unbundled EPS, i.e. not included in the package, compliant with USB-compatible power delivery standards (e.g. IEC-EN 62680).
