Design criteria based on

GB GB-4943

Note: 1) the over detection indicators are measured under the following conditions:within the range rated input voltage and rated output load ,environment is 25 ℃, 85% RH,no wind

2) output DC voltage ripple detection:With a length of 30cm 1mm2 cross section one end is 0.1μF and 0.47μF bypass capacitor in parallel twisted wire detection points were detected 100Hz

Frequency ripple maximum peak Vp-p100Hz and integrated ripple maximum peak Vp-pmax

3) Li voltage regulation: a load of ratings,Input voltage fluctuation in the nominal range ;Lo Load Regulation: the rated input voltage and load variations from zero to rated.
