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 ofbandwidth 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.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.
7.5V when the load factor 0-50%, the switching power less is reduced by burst operation, which will cause reipple and ripple noise to go beyond the specifications.
8.The ambient temperature derating of 5ºC /1000m is needed ffor operating altitude greater than 2000m (6500ft)
9.The power supply is considered a component which will be installed into a final equipmentt . All the EMC tests have been excecuted by mounting the unit on a 360mm*360mm metal plate with 1mm of thiickness . The final equipment must be re-confirmed that it still meets EMC driectives.
