NOTE
1.All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25¡æ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12¡åtwisted pair-wire terminated with a 0.1¦Ì & 47¦Ì parallel capacitor.
3. Tolerance: includes set up tolerance, line regulation and load regulation.
4. 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.
