NOTES

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load, and 25°C ambient temperature.

2. Ripple & noise are measured at 20MHz bandwidth by using a 12" twisted pair-wire terminated with a 0.1uF& 47uF parallel capacitor.

3. Tolerances include set up tolerance, line regulation, and load regulation.

4. Line Regulation is measured from low line to high line at rated load.

5. Load regulation is measured from 0% to 100% rated load.

6. The power supply is considered a component, which will be installed into final equipment. The final equipment must be re-confirmed

that it still meets EMC directives.
