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. Derating may be needed under low input voltage. Please check the derating curve for more details.
	5. 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.
	6. 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 “EMl testing of component power supplies.”
