Note:1.All parameters not specially mentioned are measured at 230VAC input, related load and 25of ambient temperature.
|
|
2.Wave&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.
