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.    
4. Derating may be needed under low input voltage. Please check the derating curve for more details. 
5. The power supply is considered a component which will be installed a final equipment. The final equipment must be
re-confirmed that it still meets EMC directives.      
6. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the
set up time.
