1. All parameters NOT specially mentioned are measured at230VAC 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. All the EMC tests are been executed by mounting the unit on
a360mm*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 “EMI testing of component power supplies.” (as available on http://www.meanwell.com)
5. The over temperature protection (OTP) is the built-in function of the control IC (U1). The activating level described above is based on the specification
provided by the IC manufacturer.
6. Touch currentwas measured from primary input to DC output.
