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 and 47uf parallel capacitors.

3.Tolerance includes set up tolerance,line regulation and load regulation.

4.Derating output is required under low input voltage.Please refer to derating curve for details.

5.The power supply should be considered as a part of the components in the system.All EMC tests will test samples on a metal iron plate with a thickness of 1mm,a length of 360mm and width of 36mm.

6.Please contact with SMUN customer service for more details.
