VOLTAGE TOLERANCE Note.3

1. All parameters NOT specially mentioned are measured at normal input (A:12Vdc , B:24Vdc) , 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 0.1 f & 47 f parallel capacitor.μμ

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. 3 seconds max., please refer to peak loading curves.

6. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with

the EMC directives. For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.
