DC Cable selection

Rate this topic

Recommended Posts

Over the past 9 months I’ve upgraded my streaming network with tri-band router and Linear Power Supplies throughout. I then added Synergistic Research ethernet cables and placed the PSs on Artecama mini racks. The improvements were akin to upgrading amplifiers, DACs or Servers.  So now I’m looking at DC cables. My current installation uses regular 1m twisted pair DC cable and I’d like to try something a little more errrr optimised.  I checked the Ghent website and was blown away by the number of different brands, topologies, screening possibilities etc.  Given that we’re talking 4 cables throughout a dedicated 5GHz band wi-fi installation,  I would set a budget of say £150.00 per cable (budget, not target!). Given the application, are there any obvious choices regarding topology, conductor and connector selection? I’ve read enough about DC cables to ensure I’m well informed but at the same time due to the sheer volume of information and opinions,  thoroughly confused. Would really appreciate some guidance from anyone who’s put some time and effort into evaluating/optimising DC cabling. Thanks

No.

 

What about avoiding the DC cables at all ? I mean, I don't see any here. Yea, phone chargers.

5V Cable Modem

5V Router

5V WiFi Extender

5V AQVox Ethernet Switch  

 

There are no SMPSs anywhere near my system or its mains supplies

Except probably on the PCB's of the above kit...

 

At DC you can look at Resistance, capacitance and inductance of the cable (and whether it can carry the required current and voltage safely)... probably the most important factors.

What are the models for 5V router and WiFi extender?

Memory glitch. The Modem and Router are 12V 5amp.  The extender was 230V into a 5V DC output SMPS which I removed and replaced with the DC3

Can't offer help on DC cables and don't want to send the thread off the rails, but what's an Artecama mini-rack?  I come up empty when I Google. 

Sorry Mike, my spelling was always a bit shirty.  Atacama.....yea, that’s the one. Nice bit of kit....really worth the money IMO

The Gotham JSSG360 is probably the best.
