8. Please Note

1.All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.

2.Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1 uf & 47uf 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.

5.Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
