**NOTE*| 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1F & 47F parallel
capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. 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 360mm360mm 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 https://www.meanwell.com//Upload/PDF/EMI_
