Inside the new Korad KA3305P linear PSU

Scottjd:
I decided to do a review on this unit. I know some bugs have been mentioned, this one I tested and reviewed is the latest with none of the bugs mentioned in this thread.
I also wanted to post the review since I know some people asked about a video.

TORCH: I hope you don't mind, I also put this thread in the description of my video for people that want to see detailed photos of the internals since you have posted such nice photos.

Hi,

As I was in search of a PSU too and having read a lot I decided based on many of the opinions here to get a KORAD KA3305P power supply.

I got it yesterday and started to learn it.

OK with the unit there was a CD, a USB cable as well as 2 (two) yes 2(two) power cables with banana and crocodile clamps, but, yed but ... after seeing the images of the burnt PSU



and having seen in You tube the tear down of a similar unit by bigclivedotcom in which he analyzed the possible why of the fire



the first thing I did with the cables weas to inspect how the ends where mounted and ... SURPRISE ...

The same way as in bigclivedotcom video.

Well I am going to make a good connection by tinning the screwable end and soldering the cable to the crocodile.

I would like to thank all of you for those good messages which help a lot for taking decisions.

Attached some images of how I got the cables.

best regards Rainer

Congrats on the new power supply. It’s not the burnt one, right? JK
I don’t remember if I mentioned this in the newer triple, but I know I do mention it in the first kora triple older one I reviewed to just ditch the cables. I think the other one I didn’t even mention them bakes it came with? But I dint really remember.
Depending on the power supply you have, you want the cables to be good quality with low resistance. You can even get nice ones without spending to much from Frankie over at 99centHobbies

Hi Scott,

I got the KA3305P. Your review video was one of the main reasons I bought this brand.

Well as having read it comes with no cables I ordered some cables specifically the Brand Elenco and Type TL-16. Having seen the images on Amazon I thought they were good and OH what a deception. They are even stiffer then the ones supplied with the KORAD PSU. On the other side I also ordered some other cables from Elenco specifically the BNC cable type TL-3 as well as the TL-12 and surprisingly they are better then their own TL-16. The pair of Elenco TL-16 cost about US $ 8.00

I live in Mexico and it is even nowadays not so easy to find good stuff here. Unfortunately Mexican consumer wants everything cheap and the sellers adapt to it and if I shop in stores with good quality the stuff costs nearly double or triple the price somewhere else like in Europe or USA.

Already happened with a Arduino shield for a NANO. I plugged it into the power supply and PENG my NANO fried. Before that I had already contacted the Mexican seller to tell him that some soldered parts were all croocked on the PCB and his answer was ... Well you know you bought chinese and that is the quality I can sell. I ussed to sell better stuff but nobody bought it ... As you can see they do not know how to sell and go the easy way ...

So far at the moment my current requirements are not big so the cables more or less do work for me. Mainly Arduino projects but I was tired not being able to play with voltages and learn more about electronics.

Will keep searching for cables

What I found out is that if I have channel 1 voltage at 0.00 I can nor adjust channel 2 in any way. Getting the adjustment up to 0.01V in CH1 then I can adjust CH2 :-) I know it is nonsense not to have something adjusted but it happened by pure curiosity that I found it out. Same happens with the current adjustment. 

regards Rainer

Can anyone share the dimensions of the KA3305P? It looks like the dimensions listed by SRA are incorrect.
