Note1.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.Line regulation is measured from low line to high line at rated load.
5.Load regulation measurement: from 0% to rated load of 100%
6.In accordance with the requirements of GB4943.1 power applies only to an altitude of 2000 meters in the following areas and non-tropical climate conditions for Safe use.
7.The power supply is considered part of the system components, to be with terminal equipment related to electromagnetic compatibility Relevant confirmation..
