1. All parameters NOT specially mentioned are measured at 800Vdc input, rated load and 25
of ambient temperature.
2. Ripple & noise are measured at20MHz of bandwidth by using a 12" twisted pair-wire terminated witha0.
&4 _
parallel capacitor.
3. Tolerance: includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltage. Please check the derating curve for more details.
5. 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).
6. 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.
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.”

parallel capacitor.
3. Tolerance: includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltage. Please check the derating curve for more details.
5. 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).
6. 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.
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.”
