NOTE|

All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C 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.
Line regulation is measured from low line to high line at rated load.
Load regulation is measured from 0% to 100% rated load.
The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. 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 http://www.meanwell.com)
The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000m(6500ft).
