All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
Tolerance : includes set up tolerance,line regulation and load regulation.
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.
Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
