note

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.Line regulation is measured from low line to high line at rated load.

5.Load regulation is measured from 0% to 100% rated load

6.The ambient temperature derating of 5℃/1000 m is needed for operating altitude greater than 2000m(6500ft)

7.The power supply is considered as a component which will be installed into a finalequipment.The final equipment must be re-confirmed that it still meets EMC directives.For guidance on how to perform these EMC tests.
