Aug 19, 2021 at 14:27 comment added Lundin Now if you are looking at industry standards, you'd place a 230VAC -> 24VDC converter somewhere, preferably buy a pre-made from a well-known vendor. Then you would power your devices with 24VDC distributed, and place a local 24VDC -> 5V switching step-down converter on the node itself. That way you don't have to care if you lose a lot of volts along the way due to voltage drop. But probably whatever you are powering that needs 10A should be powered separately and not from your 5V digital logic supply.
Aug 19, 2021 at 14:21 comment added Lundin What's a "controller"? Which standard to use depends on which bus you are using. And distances matter a lot too. 5V with 10A means massive problems with voltage drop - if you want it to start as 5V, end as 5V while drawing 10A through it, you'll need copper diameter the size of an elephant. So what's the actual problem you are trying to solve here? The question is too broad and lacks details.

Aug 19, 2021 at 9:22 comment added jcaron Do you really need 50W or is that just a guess? Recent versions of PoE (802.3bt aka PoE++ types 3 and 4) support 51 and 71 W, but as they're pretty new you'll have a lot less choice. If you can actually fit in 802.3at (PoE+, type 2, 25.5W) or 802.3af (PoE, type 1, 13 W) you'll have a lot more choice.

Aug 18, 2021 at 11:00 comment added Criticizing Israel not allowed ^ don't overthink things. Just make it whichever way is simplest. And why does the cable need to be standard - what's wrong with just buying a cable?

Aug 17, 2021 at 15:28 comment added Boann Probably easier to use separate cables.

Aug 17, 2021 at 8:22 comment added oakad Use ethernet over power cable adapters. Very handy, good bandwidth, very high power on 2 conductors: netgear.com/au/home/wired/powerline/plp2000 (NetGear is just an example, plenty such products around).

Aug 16, 2021 at 23:48 comment added dandavis 5v is a bad/expensive way to send 50w. If you're making one thing, just use buck regulator module at the device end of the cable and feed it 24 volts instead of 5 from the supply end.

Aug 16, 2021 at 17:10 comment added Tyler @Fred Digikey also offers a wide selection of connectors for multi-conductor cables...

Aug 16, 2021 at 16:23 comment added user57037 Seems like PoE type 3 can deliver 51 Watts to the load. With an efficient buck, you can just about get 10 A at 5V. PoE type 4 can deliver 73 Watts to the load which seems ample. These versions of PoE are new-ish at the moment and I don't have experience with them. I am just calling it to your attention.

Aug 16, 2021 at 15:55 comment added Fred I guess i could just use a 4 wire cable then. I was hopping for a nice connector to go with it but i ll leave with that i guess. Thanks for the help.
Aug 16, 2021 at 15:50 comment added Tyler Digikey has a large selection Link is that not what you are looking for?
Aug 16, 2021 at 15:14 comment added Fred @TonyStewartEE75 The interface is not defined yet and at this point can be anything that fit my requirements.
Aug 16, 2021 at 15:13 comment added Fred @Tyler I m looking for a multi conductor cable that can carry power and control signals and that i can buy online at "mainstream websites" ideally, not some niche industrial thing.

Aug 16, 2021 at 14:47 comment added D.A.S. It’s atypical ,so no std., it depends on your interface specs to make it work.
Aug 16, 2021 at 14:43 comment added Tyler Are you looking for a 'standard' or a 'standard cable'? IE a multi-conductor cable that can carry power and control signals.
