| NOTE |
| 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25ºC 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. 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 a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. |
| 7. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time. |
