1.All parameters NOT specially mentioned are measured at 230VAC input,rated load and 25℃, 70% RH temperature.

AC intent voltage testing: measured at 50% loading and at the end of connector.

2.Ripple & noise are measured at 20MHz of bandwidth by using a 20"twisted par-wire terminated with a 0.1uF &

47uF parallel capacitor.

3.Tolerance:includes set up toletance,line regulation and load regulation.

4.Line regulation is measured from low line to high line at rated load.The power supply is considered a

component which will be installed into a final equipment.

5.The dinal equipment must be re-confinnned that it still meets.EMC directives.For guidance on how it

perform these EMC test,please refer to EMI tesing of component power supplies.
