note 1. All parameters NOT specially mentioned are measured at 230VAC input,
rated load and 25°C 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.
