SAFETY STANDARDS

RIPPLE & NOISE (max.)

Note.2

VOLTAGE TOLERANCE

Note.3

1. All parameters NOT specially mentioned are measured at 230VAC 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. Derating may be needed under low input voltages. Please check the derating curve for more details.

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 360 360

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)

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).
