2.3.3 Ripple voltage test circuit

Figure 1. Ripple voltage test circuit

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.
