We need to start another thread when we get into these, pretty sure it's off topic in this Fechter limiter thread. :lol:

To get back On Topic, I ordered enough parts from Mouser to make 4 limiter boards, so I'm just gonna take some project boards from Radio Shack and build them up. It wil be my first of such endeavors, I hope it's mostly straightforward.

I got mine today, and its HUUUGGE! A serious looking supply for sure.
I started a thread where we can throw all info on these supplies.

fechter,

Will this circuit for the 24-35V range work okay with the 600W 24V series (SE-600-24) meanwells? Do you have any boards left?

Thanks!

I haven't seen one of those supplies, but I assume it is similar to the smaller ones.
At that current level, I think the shunt would need to be doubled up, but otherwise should work OK.

I don't have any of the newer boards left, but I have a few of the older ones that require a little modding with jumper wires. They only have one spot for the shunt though, so would take some modding for two shunts.

It wouldn't be that hard to make one on a perf board.

I'll dig around in the files and post the latest configuration when I get a chance.

Thank you.. I figured the perf board wouldn't be that hard either. It would need to be two beefier shunts in parallel, that each have double the resistance of the one in the BOM, correct?

Will this work for the 48V 1200W version SCN-1K2-48?
Any left?

Sorry, no boards left, but it's not hard to DIY on a perf board.

Not sure about that model. Most power supplies will work with this though. The trick is to find the spot to tie in the sensing line. For that power level, you will need at least two shunts in parallel to handle the current.

Wait, this just limts current, it doesn't cut charing after the current drops below set point? I'm sure I've seen your schematic for the circuit which does that, but I can't find it now. Can you post it here?

Ah, looks like Fechter got there before I found it...the one I posted is slightly different I think...I edited it a bit, to match the board the gary at tppacks sent me

Now I am confused. i need 2 cards to do this?
I thought the Meanwells was constant voltage by default..

No, just the one board,

There were two designs of board, the basic one with just one adjustment pot that just limits current. They then created a second design, which is the two schematics above.


This second one, also monitors the current flowing into the battery.
When the current drops below the limit (set by VR3) then the board causes the output voltage of the meanwell to drop. the amount it drops is set by VR1 ..the float voltage setting

The version 4.2.5, with the three pots, was there ever a professionally made board for this design? I have a good relationship with a circuit board manufacturer locally. If there is any interest I can have them made and distribute them here for other members. The meanwell chargers are a great cheap option for newbies like myself and I think it would be a worth while project for everyone.

Yes there was versions of boards for three pot 4.2.5 4.2.6...Gary Goodrum at tppacks sold them ..They are no longer on the site, as there were supposed problems with them...but

I have got three of them and two are up and running on both my meanwell builds.
once the issue with gettting the componets in the correct way around was sorted, they worked fine.

one of the transistors...or FETS..can't remember had slightly diffferent versions..and the pinout was changed..BS107A and then BS107B or something similar.

If you read up you see Richard mentionin ghtat there were problems, but as I said, above that issue with the pinout they work fine.

And again..another BUT....
i am not using mine for current limiting...I have done that with the mod on the board..R37. The issue was supposed to be that these boards caused a buzz...but these things tend to buzz a bit anyway when current limtied .I only use these 3 pot boards as end of charge monitor and for the LED that changes from orange to green when done charging

Speak to Gaary at tppacks he may sell you them

I've got one from Fechter that I didn't have a chance to put together, because my Meanwell failed just before I got the boards in. :( :( :( :( :(

I have a 48 volt 500 watt Meanwell that would love to meet that board. I'll take it if you want to sell it!

I do have a picture of the PCB for the three pot version..but I am not going to post that up just yet I am afraid. It is not my design..and I can't go sharing something like that without the OK of Gary or Richard first..it is there design and they do have businesses to run, if Richard can OK, it then I can pass it on.

but not till I know I am not going to upset anyone

Totally understandable. I'm offering to have the boards made but I don't want to step on anyone's toes.
I'm sure that I'm not the only one that would love to get a few these boards. The Meanwell power supplies are well documented here on the forum and they come at a great price. I've been reading about them for a couple of weeks now. These limiter boards basically sum up a bunch of knowledge shared here already. It is much appreciated.

OK, here they are
There are three images: A front image, a rear , and then a third that is a composite, so you can see where the tracks coincide as it is a double sided board

But I would check with Gary at tppacks first, before you go spending money and making a load. He may still have some ready to sell. They are not on the site anymore, but he may still have some
