All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25�C of ambient temperature.
Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47 uf parallel capacitor.
Tolerance: includes set up tolerance, line regulation and load regulation.
De-rating may be needed under low input voltages. Please check the de-rating curve for more details.
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.
