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 0.1uf & 47uf parallel capacitor.  3. Tolerance : includes set up tolerance, line ragulation and load regulation.  4. The power supply is considered a component which will be installed into final equipment. The final equipment must be re-confirmed that it still meets EMC directives.  5. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power.In case the adjacent device is a heat soure, 15mm clearance is recommended 6. Derating may be needed under low input voltage. Please check the derating curve for more details. 7.Please contact with SMUN customer service for more details.
