PROTECTION
1. All parameters NOT specially mentioned are measured at 36,110VDC 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. Strongly recommended that external output capacitance should not exceed 5000uF. :(Only for RSD-300-5 / -12)
5. 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 mm* mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives.360 360 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)
6. The ambient temperature derating of 3.5 /1000m with fanless models and of 5 /1000m with fan models for operating altitude higher than 2000m(6500ft).℃℃
