NOTE

1.All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12twisted pair-wire terminated with a 0.1 & 47 parallel capacitor.

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