All measurements performed at room temperature, 47 Hz input frequency.
8.1 Efficiency
8.1.1 Active Mode CEC Measurement Data
The table below lists the operating efficiencies at specific load points measured at the
nominal input voltages. For the purposes of the CEC & EPA calculations, 2 W output was
taken as the 100% load point. The CEC & EPA spec shown in the table below was
calculated based on 2 W as the nominal 100% load.
