Meanwell S-350-24 or 48 volt DC power supply

Post by dozentrio » Apr 13 2018 1:53pm

I need to replace my Meanwell bulk charger and can't find any good sources for the old easy to mod (R33 mod) DC power supplies. Anyone have any of these or know a source?

There are several other models we have the modification data for.

Search for a S-400-48
or
T-400-48
or
AD448.3-400W

No guarantee the ones you get today will be the exact same layout as the older ones, even if the model number matches. In most cases, I can tell from a picture of the board where the "R33 equivalent" is.

What do you want the PSU to do, for adjustments? If you just need to adjust volts and current limit, theres at least two series of MW that do this with built-in controls, like the HLG-xxxH-xxA versions, so you dont have to mod them. Theyre also potted and sealed, so no fans needed and are weatherproof and can handle the vibrations if you need to carry them on the bike.

Get a Cycle Analyst and a Multimeter, you're still a noob if you don't have at least one of each.
