So what’s the Traco parts list for that? I don’t do this stuff normally, so excited to get started and try it out.
If I’m pushing 48v up top to a roof, what’s the voltage drop? I assume these DC units can somehow be tweaked so that output can accommodate for voltage drop. What size wire is everyone using typically for this, usually 30-100 ft max length? I’m assuming it’s something like 10 AWG? At 48v and 5A and 50’ is maybe 47.5v at the end? So I would push 49 or 50v just to be safe?

I agree with others - your battery plant should be 48VDC.

If the radio freaks out above 54, just set it at 54 and you should be fine. Battery strings don’t exceed the float voltage of the rectifier. If you are worried about it float at 53.75 volts.

Any telecom equipment made for 48v I would have assumed they intended it to be used with a rectifier, and consequently I would assume it'd be ok up to at least 56v continuous; and maybe more like 60-70v for a short duration. But yeah, DC-DC converter is the fix. On 6/18/2019 11:36 PM, Sean Heskett wrote: You need to use a DC-DC converter for sensitive equipment like that. Meanwell has a good selection.
