VOLTAGE TOLERANCE
Note.3
1. All parameters NOT specially mentioned are measured at 230VAC
input, rated load and 25 of ambient temperature.
°C
2. Rippl
e & noise are measured at 20MHz of bandwidth by usin
g a 12"
twisted pair-wire terminated wit
h a 0.1uf & 47uf parallel capacitor.
3. Toleranc
e : includes set up tolerance, line regulation and load regulation.
4.
The power supply is considere
d a component which will be installed int
o 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 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)
5. Derating may be needed under low input voltages. Please check
the derating curve for more details.
6. The ambient temperature derating of 3.5 /1000m with fanless
models and of 5 /1000m with fan models for operating altitude high
