Remark:

1.All technical data if not mentioned, it should be measured at 230v,rated load and 25 °c of relative temperature

2.Ripple and noise are tested at 20mhz of bandwidth via 12" twitsted pair-wire terminated with 0.1uf and 47uf parael cap.

3.Tolerance:set up tolerance,line regulation and load regulation are included

4.derating may be loaded with low input voltage, it should double check the detailed static characteristics

5.As power supply need to connected with final terminal equipment, which require the equipment to comply with EMC standard on the complete installation process again
