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 witha0.
&4
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 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. The power supply is considered
a component which will be installed into a final equipment. All the
(with FG) EMC test are been
executed by mounting the unit on
a 360mm*360mm metal plate with 1mm of thickness.
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.”
