NOTE
  1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25¡æ of ambient temperature.
  2. Ripple & noise are measured at 20MHz of bandwidth by using a 12¡åtwisted pair-wire terminated with a 0.1¦Ì & 47¦Ì parallel capacitor.
  3. Tolerance: includes set up tolerance, line regulation and load regulation.
