As far as I can tell, the PA905C4 is rated for 400v, 20A, so should not be a limitation.

Nice. When I modify it I'll post results here.

two years ago i modified 2 S350-48 for charging my 24S lipo setup.

I recently got four 200-24 meanwells which i also want to cranck up to 10A instead of 8.4.
But if i look at it i don't see which resistor i have to change.
Does anybody has some experience in modifying this model ?

YOU seem to be wanting to do the reverse of what the rest of us do to the Meanwells...we all tend to REDUCE the output current, so we do not burn them out, not icnrease the currents

To illustrate the vain conceit that the universe must be somehow pre-ordained for us, because we are so well-suited to live in it, he mimed a wonderfully funny imitation of a puddle of water, fitting itself snugly into a depression in the ground, the depression uncannily being exactly the same shape as the puddle."
