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 12″twisted pair-wire terminated with a 0.1μ & 47μ parallel capacitor.
3.Tolerance: includes set up tolerance, line regulation and load regulation.
