I guess my experience is the reverse. Having spent 40 years in telecom, seems that almost everything rack mounted is –48 if you want DC power. I don’t recall ever finding +48 rack mounted telecom equipment.

My one Eltek site has an old Purewave WiMax basestation that I am about to decommission but I will need +48 and I don’t want to put in a DC-DC converter if nothing will be running off the -48.

This seemed to be something that would work for us (Mean Well SE-1000-48). Any thoughts or pros and cons that yall have found with this unit. Any units of similarity that might work well in place of this one.
