Seems impossible to find adapters for RG6 to DC so I just used these on a short length of RG6 and some heat shrink....

Thanks all, some interesting ideas. In my situation I (at least to start with) don't have to run things too far, so don't see the point in starting high and then still needing an adaptor to reduce the voltage. Also seen some compact DIN mountable PSU's which might fit my needs.

Plenty of DIN PSUs on Aliexpress etc

Can highly recommend DIN fuse terminal block connectors too, just pop it out if you need to reset or isolate a device

Voltage drop is a PITA with DC cabling.

There are a bunch of calculators online that choose cables based on acceptable voltage drop, distance and amps.

You generally limit voltage drop to 3% for electronic devices.

Hi,

Also interested in this topic.

SumnerBoy:

Very interested in this as well (but don't have anything to share sorry).

A mate is almost at pre-wire for his new house and asked me about wiring/lighting options. I am meeting his sparky next week to discuss. I like the idea of running low voltage wiring around the house to all lights and light switches. Then run them all back to a central location.

Just curious as to if this meeting took place and what the outcome was?

The sparky agreed about the control wiring but not the loads. Voltage drop over long runs the issue.

I run a large amount of devices in my property on 48V PoE, have so far had no troubles at all and allows me to just run Cat6 wherever I need power.
