Having a hard time figuring out the exact part/price for something like this.
Which Meanwell part would take 48v and make it 50v or 54v 5A?

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.

Is there any way to assure it doesn’t float/charge above 54v, or maybe even just 50v?

So can the 7bc2 be adjusted slightly to output 50v instead of just 48v? There will be some loss going 100’ or so, right?

Can you guys give me an idea or example of the following? I want to take standard AC 15A in from a breaker outside the box. And using maybe one or two 12v 105AH AGM batteries, supply 50v 6A up the side of the house. I have never ordered DIN parts like this, guess I don’t have to use DIN, but would be nice. Having a problem finding a DC to DC converter that takes 12v and upconverts to 50v 5-6A. Is this the cost effective method?
