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 luf & 47uf parallel capacitor
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. The power supply is considered a component which will be installed into a final equipment.
