1. All parameters NOT specially mentioned are measured at400VAC 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. Dual phase operation is allowed under certain derating to output load.
Please refer to derating curves for details.
5. Installation clearances
: 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power.
In case the adjacent device is a heat source, 15mm clearance is recommended.
6. The ambient temperature derating of 3.5
/1000m is needed for operating altitude higher than 2000m(6500ft).
7. 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. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”
