Note

1. All parameters not specially mentioned are measured at 12,24,48VDC input,rated load at 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1 uf &47 uf parallel  capacitor.
3. Tolerance : includes set up tolerance ,line regulation and load regulation.
4. The power supply is 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 er-confirmed that it still meets EMC directives.For guidance on how to perform these EMC tests,please refer to “EMI testing of component power suppliers”.
