      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 0.1uf & 47uf parallel capacitor.

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