Hi Guys,
When I disassemble a machine "made in China", it has a AC/DC module low-power ( I guess it's 12V/1A output).
I observe these design and discover something weird. It has (look like) the tuning traces and serial with MOV. MOV'name is "vdr 10d561k"
As in my picture below.
It is connected directly to 220VAC input before come into capacitor and common choke.
So, what is the purpose of this tuning trace ??
It's the first time I see this kind, please explain clearly.
Thank you.
