notes

1. all parameters not specially mentioned are measured at 110~277VAC 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 .
