Inside the new Korad KA3305P linear PSU

Opened it up and after finding no obvious loose connections, I re-seated every internal plug, which fixed the problem. Great PS at an even greater price!

SantaClaw:
Excellent news, yeah, it's a good psu for the money :)

FWIW, I got this Korad KA3305D for $139 delivered from SRA Solder. Although they are sold as refurbished units, the one I got looked brand new and was shipped in the factory Korad box. The only difference being that the manual was a black and white printout of the factory manual. Hard to get anything close to this for that price, especially since I didn't need the Programmable model. So far I am extremely pleased with this unit.

bitwelder:
Gotta ask: is it possible to find anywhere the USB module used in the Korads, or are the schematics available?
I have a rebranded version of the Korad dual PSU that doesn't have the USB interface (but has the metalwork done to host it), so if possible it would be nice to 'mod' it.

GREAT info and thank you so much for this thread.

I am just getting into electronics and am trying to get a few necessary tools without breaking the bank as I am new and this will be at a hobby level.  I just got a Bryman multimeter and am looking at this power supply.  It was fun reading the past 6 pages of dialog on this and helps give me a feeling for what you have been experiencing.  It seems like a winner at this price range to me.

I'm interested in doing some Arduino and Raspberry Pi projects for various purposes(mostly sensor monitoring and graphing of collected data currently, etc).  I have a LOT to learn and need to get the basics down but it's going to be a fun ride.

Anyway, thank you for all the info related to this PSU.   :-+
