PACKING
1. All parameters NOT specially mentioned are measured at 12, 48VDC 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
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. (as available on http://www.meanwell.com)
5. To insure proper operation, a 47uF/100V electrolytic capacitor with Esr <1
Ω
must be added to the input line.
