Hi
I trying to design myself a linear psu using a 24v rms center tapped transformer upto 20v around 2A. It's digitally controlled so it needs a 3.3v supply. Due to being a linear supply I've put in a 12v fan. The easiest way to implement this AFAIK is to use one of these transformers that have a 5v and 12v secordary then regulate it to 3.3v and 12v resopectively
However am an amateur as my name suggests. Why is the input voltage 265v but the primary 65 to 130v? Is the pimrary not where the input voltage goes? Any help on a driver would be appreciated
Here's a link to the transformer am thinking of using
