9.1.1 Active Mode Efficiency (CEC) Measurement Data
All single output adapters, including those provided with products, for sale in California
after July 1^st, 2006 must meet the California Energy Commission (CEC) requirement for
minimum active mode efficiency and no-load input power consumption. Minimum active
mode efficiency is defined as the average efficiency at 25, 50, 75 and 100% of rated
output power, based on the nameplate rated output power of the supply.
