Default Confirming umbilical connector choice

These look suitable for an umbilical for the Edcor 131 power supply but I wanted to check with the knowledgeable. It will only be the PS on the umbilical, everything else is staying PCB side.

Just need to find some 9 conductor 600V rated wire; a rummage around in the basement to begin with then off to Google

So I found a thread that offers up different suggestions that clearly do work.

Checking it out!

Those were 9 pin and now I am thinking I might need more. Not sure why I am thinking that, might be the Riesling

I use Tyco connectors. They are not expensive and good enough for audio amps.

Thanks Evan, they look like just the thing and the cost is a real benefit

18 gauge insulated wire for the connections rated to 600V should do the job, right?

Thanks.

So connectors are sorted and the cable is sorted so ow just the braid.

If I use this cable in 20g NEOTECH - Solid Core Copper, Teflon Jacket (UP-OCC Mono-Crystal design) and run a grounding wire through the umbilical do I need shielded braid?

Thanks.

I wouldn't advise running solid core in an umbilical - it's not made for continual flexing and may be prone to breaking, depending how much you move the umbilical.

Also, IMO, and if you believe in exotic materials more power to you, but there's no advantage to this wire over standard $0.18/ft 600V stranded.

Thanks for the advice JP, stranded wire it is then. I usually net out in the low end of exotic but I understand what you mean. Sometimes I just can't resist
