For adapters that are single input voltage only, the measurement is made at the rated
single nominal input voltage (115 VAC or 230 VAC); for universal input adapters, the
measurement is made at both nominal input voltages (115 VAC and 230 VAC).
To meet the standard, the measured average efficiency (or efficiencies for universal input
supplies) must be greater than or equal to the efficiency specified by the CEC/Energy
Star standard.
*Although the CEC standard does not apply to this design, the data are provided for
reference.
More states within the USA and other countries are adopting this standard. For the latest
