NOTE 1.All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25ºC 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 up tolerance, line regulation and load regulation.
