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 0.1μ & 47μ

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. The final equipment must

be re-confirmed that it still meets EMC directives.
