NOTE

1. All parameters NOT specially mentioned are measured at 230VAC 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. Line regulation is measured from low line to high line at rated load.
5. Load regulation is measured from 0% to 100% rated load.
6. Length of set up time is measured at cold first start. Turning ON/OFF
the power supply very quickly may lead to increase of the set up time.
7. 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 direc ves. For guidance on how to perform these EMC tests, please refer to EMI tes ng of component power supplies.
8. The ambient temperature derating of 5℃/1000m is needed for operating altitude greater
than 2000m (6500ft).
