I wanna bring this up once again:

Any ideas or experience making a resistor-pot mod for changing the output Current ??
like the output voltage mod, just for current.

The reason for it would be to make a slow and fast charging switch to the Eaton

Someone experienced has to find where it measures current and how to trick it.. I have not found it. Or maybe a logic switch to MC and change firmware.

Please how you was able to get 90v out of it?
Higher resistence of pot means higher voltage.. but my APR doesnt go over exactly 70v even open circuit (cut line, no pot)

only allows to crank up to 67v.
How low could you set the output voltage minimum ? (with both mods pot and programmer ?)

OK. Done firmware patch. Now my upper voltage is capping at 75V and the lowest i can go is 43.4V

Some 9V out, bummer

Can you check your resistor value?

Could someone tell me the resistance range of the POT to use to adjust the voltage from 43 volts to 57 volts?

If you have 4 of these in series for 200 volts and want to adjust the amps. Would you need to adjust all 4 PSU, or can you just adjust 1 PSU?



Thanks

Allex, I'm trying to reprogram a couple of APR48's and have followed all your very helpful info on doing this. I have 2 problems...firstly, I get an error message regarding a clock error when downloading the config hex file from the PSU, although it does appear to download the data. I then save the downloaded file OK but can't open it using Eaton.exe, it just comes up with File Error. I have downloaded a supposed good config hex file from a Russian web site and that does exactly the same. Interestingly, my hex file looks rather different to the supposed "good" Russian one, although I can decode the model number etc. from the HEX ASCII data. Any ideas?

Hi Downdale,

Take a look at my post on page 4 at 10:30

Hope that helps

I use these Eaton modules as chargers for about 2 years already (made by Russian engineer). I often have the same problem: one of the fans stops and need to move its blades with a toothpick to work again. It continuously happens with all chargers made by that guy. Does anybody else have this issue or there is some individual defect?

Thanks

Does anyone have the Eaton patch .exe???

Google won't let me download it with the link provided because it thinks it includes a virus...

I decided to go a little different route. D9 connectors to a breadboard. I'll be using a Raspberry Pi I have to do the AVR flashing since it has a fancy 26 pin GPIO. I'm building this one for my E-bike, but the end game is to have a bank of them on my diesel/electric drive sailboat project, which is already going to be automated with Pi's.
