NOTE

1. AII parameters NOT speciaIIY mentioned are measured at 230VAC input, rated Ioad and 25℃ of ambient temperature.

2. RippIe & noise are measured at 20MHz of bandwidth bY using a 12" twisted pair-wire terminated with a 0.1uf & 47uf paraIIeI capacitor.

3. ToIerance : incIudes set up toIerance, Iine reguIation and Ioad reguIation.

4. Derating maY be needed under Iow input voItage. PIease check the derating curve for more detaiIs.

5. InstaIIation cIearances : 40mm on top, 20mm on the bottom, 5mm on the Ieft and right side are recommended when Ioaded permanentIY with fuII power. In case the adjacent device is a heat source, 15mm cIearance is recommended.

6. The power suppIY is considered a component which wiII be instaIIed into a finaI equipment. The finaI equipment must be re-confirmed that it stiII meets EMC directives. For guidance on how to perform these EMC tests, pIease refer to “EMI testing of component power suppIies.”

7. The ambient temperature derating of 3.5℃/1000m with fanIess modeIs and of 5℃/1000m with fan modeIs for operating aItitude higher than 2000m(6500ft).
