    NOTE 1. All parameter NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
    2.2. Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uf & parallel capacitor.
    3. Tolerance: includes set up tolerance, line regulation and load regulation.
    4. Line regulation is measured from low line to high line at rated load.
    5. Load regulation is measured from 0% t0 100% rated load.
    6. The power supply is considered a component which will be installed to a final equipment. All the EMC tests are been
     executed by mounting kthe unit on a 230mm*230mm 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 ”EMI testing of component power supplies.”
    7. The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000mm(6500ft)
