Notes

1. All parameters NOT specially mentioned are measured at 110V/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 .
