9.2 Energy Efficiency Requirements
The external power supply requirements below all require meeting active mode efficiency
and no-load input power limits. Minimum active mode efficiency is defined as the average
efficiency of 25, 50, 75 and 100% of output current (based on the nameplate output
current rating).
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 standard.

For the latest up to date information please visit the PI Green Room:
9.2.1 USA Energy Independence and Security Act 2007
This legislation mandates all single output single output adapters, including those
provided with products, manufactured on or after July 1
active mode efficiency and no load input power limits.
Active Mode Efficiency Standard Models
No-load Energy Consumption
This requirement supersedes the legislation from individual US States (for example CEC
in California).
