The ripple is obtained by measuring the peak-to-peak value using an oscilloscope with a bandwidth of 20MHz. When the DC output is fully loaded, AC rated input, and an ambient temperature of 25℃, the output terminal is connected in parallel with a 10uF electrolytic capacitor and a 0.1uF ceramic capacitor.
The ripple is measured from peak to peak with band width limit of 20MHZ, By passed at the end of connector with 10uF electrolytic and 0.1uF ceramic disk capacitor under DC output full Load, AC nominal input 25℃ambient temperature
Note2:
The output voltage rises from 10% to 90%, rated load.
Output voltage is increased from 10% to 90%, rated load.
