Test conditions and notes5
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25β 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. The final equipment must be re-confirmed that it still meets EMC directives.
- 5. The ambient temperature derating of 3.5β/1000m with fanless models and of 5β/1000m with fan models for operating altitude higher than 2000m(6500ft).
