Note 1: At cold start. (More current may flow at restart.) Note 2: Ripple noise is measured with a 100 MHz oscilloscope, using a 1:1 probe. Note 3: Output characteristics are measured at the output connector. Ripple noise is measured at a point 5 cm from the output connector, with 47 µF electrolytic capacitor attached at that point. * "Rated input/output conditions" means that the switching power supply is operated under the rated input voltage, rated output voltage, rated output current, rated frequency, and at an ambient temperature of 25°C and 60% humidity.
