17 / 32 page ![]() 08-Nov-2005 EP-89 6.2 V, 322 mA Adapter Nameplate Output (PO) Minimum Efficiency in Active Mode of Operation < 1 W 0.49 × PO ≥ 1 W to ≤ 49 W 0.09 × ln (PO) + 0.49 [ln = natural log] > 49 W 0.84 W For adapters that are rated for a single input voltage, the efficiency measurements are made at the input voltage (115 VAC or 230 VAC) specified on the nameplate. For universal input adapters, the measurements are made at both nominal input voltages (115 VAC and 230 VAC). To comply with the standard, the average of the measured efficiencies must be greater than or equal to the efficiency specified by the CEC/Energy Star standard. More states within the USA and other countries are adopting this standard, for the latest up to date information on worldwide energy efficiency standards, please visit the PI Green Room at: http://www.powerint.com/greenroom/regulations.htm 9.2 No-load Input Power 0 0.02 0.04 0.06 0.08 0.1 0.12 0 50 100 150 200 250 300 Input Voltage (VAC) Figure 8 – No-load Input Power vs. Input Line Voltage, Room Temperature, 60 Hz.
