9.1.1 Active Mode 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. Minimum active mode
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:
Nameplate
Output (P_O)
<1W
≥ 1 W to ≤ 49 W
> 49 W
Minimum Efficiency in Active Mode
of Operation
0.49 × P_O
0.09 × ln (P_O) + 0.49 [ln = natural log]
0.84
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).
