1. All parameters NOT specially mentioned are measured at400VAC 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.
5. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quick may lead to increase of the set up time.
6. The ambient temperature derating of 3.5
/1000m with fanless models and of 5
/1000m with fan models for operating altitude higher than 2000m(6500ft)
