NOTE| 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load, and 25℃ of ambient temperature.

2. No minimum load required.

3. 33% Duty cycle maximum within every 30 seconds. The average output power should not exceed the rated power.

4. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.

5. Tolerance: includes set up tolerance, line regulation, and load regulation.

6. Derating may be needed under low input voltages. Please check the derating curve for more details.

7. Touch current was measured from primary input to DC output.

8. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitudes higher than 2000m(6500ft).

9. The power supply is considered a component that will be installed into the final equipment. 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 )
