Notes

1. All parameters NOT specially mentioned are measured at 110V/230VAC input , rated load and

   25℃of ambient temperature.   

2. Ripple& noise are measured at 20MHz of bandwidth by using a 12”twisted pair-wire terminated with

 a 0.1uf &47uf parallel capacitor.   

3. Tolerance:includes set us tolerance,line regulation and load regulation . 

4. Loading should be 60-100%.
