The reason I mentioned the 48V not being necessarily ideal is some electronics are made with almost zero headroom above their limits.
For example, I own a 12V DELTA power supply that can be adjusted to output 14VDC; however, its filter caps are only rated for 16V!
That's 2V of headroom!
Which is absolutely fine, that is the way the designers intended.
