A quick search on eBay for '48v rectifier' has made me realize it's definitely doable at costs much lower than off the shelf options...

I'll start with a few examples of what I've found.

I'm assuming one would need to figure out a way to adjust the voltage, unless you can find something pre-programmed.

(I apologize for the terrible links, I'm using the ebay app to share the item and copy the link.)
These look promising because you could parallel them together to hit your target and/or have the ability to scale them.
