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).
