NOTE
|
1.All parameters NOT specially mentoned are measured at 110VAC, 220VAC 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&10uf parallel capacitor.
3.Tolerance:includes set up tolerance,line regulation and load regulation.
