The highest I've seen is 48V, which is under the 50V "low voltage" limitation.

I followed VLM's logic and math.

VLM assumed one wire pair, 71W specification, 960mA worst case current draw == 70V+.

Which was incorrect, because there's 4 wires. In PoE classic, 2-pairs were for data + 2-pairs for power. In 4PPoE, there's 4-pairs for data and the _SAME_ 4-pairs for power.
