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 regulation and load regulation.  4. The output needs to be reduced under the condition of low input voltage, refer to the derating curve chart for details.  5. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may increase of the set up time. 6.Please contact with SMUN customer service for more details.
