2.3.2 Definition
The ripple voltage of the outputs shall be measured at the pins of the output
connector when terminated in the load impedance specified in figure 1.
Ripple and noise are measured at the connectors with a 0.1uF ceramic
capacitor and a 10uF electrolytic capacitor to simulate system loading.
Ripple shall be measured under any condition of line voltage, output load,
line frequency, operation temperature.

2.4 Overshoot
Any overshoot at turn on or turn off shall be less 10% of the normal voltage
value.
2.5 Efficiency.
Power supply efficiency typical 87%/20% Loading, 90%/50% Loading,
87%/100% Loading, at normal AC 115V voltage.
