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.
