Samlex heavy-Duty bench supply filter question
#1

Hello Everyone,
I have one of my Heavy-duty bench powersuplies made by Samlex it's 13.8 volt dc 20-25 amp supply.
What I would like to do is replace it's main filter electrolytic capacitors which it uses six 4700ufd capacitors to add up to 28,000ufd .
they used a no-named brand and I was wondering about getting some higher value capacitors to replace those six .
or should just stick with the original design ?


Here are a couple photos of this monster        


Sincerely Richard
P.S. the other thing I thought would be handy is volt and amp meter to add to it !
this unit really used seven 4700ufd capacitors

I suggest sticking with the original values. Depending upon the design if you increase the cap values too much the increase in inrush current may damage components ahead of the caps.

Hello Dale,
What I plan to do is to use a couple  of  14,000 ufd capacitors and put them in parallel and take that circuit board with the 6 4700ufd capacitors are mounted on them to the chassis .
