NOTE

1.  All parameters NOT specially mentioned are measured at 400VAC 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 & 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.  The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft}.
