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 0.1μF & 47μF 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. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”

(as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

5.  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.

6.  The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
