SPECIFICATION
NOTE
- All parameters NOT specially mentioned are measured at 230VAC input, rated load, and 25 of ambient temperature.
- Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1 μ F & 47 μ F parallel capacitor.
- Tolerance: includes set up tolerance, line regulation, and load regulation.
- Derating may be needed under low input voltages. Please check the derating curve for more details.
- The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitudes higher than 2000m(6500ft).
- 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 directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
