8 Performance Data
All measurements performed at room temperature, 60 Hz input frequency.
8.1 Efficiency
8.1.1 Active Mode CEC Measurement Data
All single output adapters, including those provided with products, for sale in California
after Jan 1
minimum active mode efficiency and no load input power.
efficiency is defined as the average efficiency of 25, 50, 75 and 100% of rated output
power with the limit based on the nameplate output power:
For adapters that are single input voltage only, then 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.
