Notes
|
1. All parameters NOT specially mentioned are measured at 110V/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 us tolerance,line regulation and load regulation .

FAQ：
What is CC and CV in power supply?
"CV" stands for "constant voltage", and "CC" stands for "constant current". Most types of load need constant voltage to operate, so if the "CV" LED is lit, it means the PSU works fine with your load.
