Yes, that make sense. No need to excuse, this is a great learning process for me. ☺ I ordered a 1000uF 63V cap and will try again when it arrive. Thank you for your assistance.

I soldered a 10k trimmer pot to R40 but when I powered the power supply I blowed one of the capacitors as you can see on the picture below. https://www.dropbox.com/s/rq765ytyt17sjrv/20160222_200153.jpg?dl=0 https://www.dropbox.com/s/ib2tyxoomksoz8i/20160222_200016.jpg?dl=0

Nice. Can I do this with a 10k trimmer pot?

Here is a video of the circuit: https://www.dropbox.com/s/ieesyv8h3xree0k/20160211_141817_001.mp4?dl=0 And here is a picture: https://www.dropbox.com/s/45zj8devjzcydvb/20160219_160959.jpg?dl=0 And a close up picture: https://www.dropbox.com/s/1lgmppbfsho8jmo/20160219_161200.jpg?dl=0 Does this...

Great. I'm looking forward to it. :)

I placed a trimmer pot across the R35 and tried to charge my 48V battery but the pot doesnt do anything. It has to be said that the current was starting at about 5A and went downward. The voltage was just 51.6V at maximum so I need to get the voltage up. Is it because the low voltage the trimmer...

Thanks. I'll give it a try.

Could you see anything on the video or picture? ☺

Here is a video of the circuit: https://www.dropbox.com/s/ieesyv8h3xree0k/20160211_141817_001.mp4?dl=0 Are you able to trace the circuit back to the shunt on this video?

Are you able to trace the circuit back to the shunt on this picture?

The number of the 16 pin chip is: 15407YH TL494CN The supply model is 48V 7.5A 360W Bought it here: http://www.ebay.com/itm/311001005100?_trksid=p2057872.m2749.l2649&var=610293600576&ssPageName=STRK%3AMEBIDX%3AIT Is it possible to reduce the current with your method on this supply?

Here is pictures of both sides of the board. Can you trace it out for me? Side 1: Side 2:

I've taken additional picture (look at the attachment under) of underside of circuit board so R35 function might, possibly, have a chance of being determined? Does R35 in this power supply controls amp output?

Thank you. How did you find out where to place the 10k trimmer pot so the current limit can be adjusted? I wonder if I can do the same on my 350w power supply...
