RIPPLE&NOISE(max.) Note.2
VOLTAGETOLERANCE Note.3
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 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. Derating may be needed under low input voltages. Please check the derating curve for more details.
For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.
