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. (ln order to meet tolerance, it is recommended that CH1 load > 10% rated current.)
	4. Line regulation is measured from low line to high line at rated load.
	5. Load regulation is measured from 20% to 100% rated load, and other output at 60% rated load.
	6. Each output can work within current range. But total output power can't exceed rated output power.
	7. 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 “EMl testing of component power supplies.”
	(as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
	8. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
	9. 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).
