Nameplate Output (W) Minimum Efficiency in Active Mode*
0 to < 1 Watt 0.49 * Nameplate Output
≥ 1 and ≤ 49 Watts 0.09 * Ln(Nameplate Output) + 0.49
> 49 Watts and ≤ 250 0.84
Maximum No-Load Energy Consumption
0 to < 10 Watts 0.5 Watts
≥ 10 to < 250 Watts 0.75 Watts
*Ln (Nameplate output) = Natural Logarithm of the nameplate output expressed in Watts

Effective July 1, 2008

Nameplate Output (W) Minimum Efficiency in Active Mode*
< 1 Watt 0.5 * Nameplate Output

> 51 Watts 0.85
Maximum No-Load Energy Consumption
Any Output 0.5 Watts
*Ln (Nameplate output) = Natural Logarithm of the nameplate output expressed in Watts
