NOTE

1. All parameters NOT specially mentioned are measured at 24VDC input, rated load and 25℃ of ambient temperature.

2. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on    a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMl testing of component power supplies.” (as available on http://www.meanwell.com}

3. 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}.
