9 Performance Data
All measurements performed at room temperature, 60 Hz input frequency.
9.1 Efficiency
9.1.1 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, 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).
