I have had great luck using cheap LED drivers. They say 110-240 vac input but they rectify the input to DC. I have used them to run 12 and 24 volt stuff off of 48 vdc and even 400 vdc. They operate down to about 35 volts dc. They are available in a variety of output voltage and current. And they are isolated. And they only cost a few dollars. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F152134115704 David Katz
