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. lnstallation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. ln case the adjacent device is a heat source, 15mm clearance is recommended.
	5. Derating may be needed under low input voltage. Please check the derating curve for more details.
	6. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the 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 )
	7. 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).
