Hello,
I have built a power supply using the attached uds file. The output voltage should be 24V but it is 50V. I have verified the components on the board are correct per the schematic. I have also checked the feedback circuit by connecting an external supply and it appears to be working. I have tried changing R12 to 20K with no effect. My thought was a problem with the transformer but the manufacturer has stated they were wound correctly. What else could the problem be?
Thank You!!!
I didn't find the right solution from the Internet.
