This is probably the most universal model of the series. Great durability, but now we will end up re-purposing some of them.

The original Power Input voltage rating was 9-60VDC in the pdf spec sheet. Now the spec sheet for the same model shows 9-72VDC.

Was there an actual power supply upgrade, or were the original power supplies very conservatively rated, but could handle 72v all along?

If the supplies are physically different, is there a way to tell, because I don't recall markings on them?

We need to know because the battery charge controllers had to be tweaked to stay within 60V.

There was a change, the 9-60V models do shut down somewhere just above 60V. The label on the front of the unit was changed as well, it will state either 9-60V or 9-72V as appropriate.

Netonix can probably tell us the revision this was changed at.
