out board power supply connection

[slr 5000]

g,day all

Just about to build an outboard power supply so i can easily switch between my different fw clones with a simple plug in/out

I have a few questions regarding the best lead to use to connect the power supply case to the amplifier case/s
i,m thinking a 3 or 5 din plug with standard 3 core mains wire

any suggestions/advice would be much appreciated

I would use a plug with meatier pins than a standard DIN plug.

Any suggestions?
i was thinking normal ac plugs but they only come on 3 pin and i need 5 pin

something like this

Check fo russian Cannon plugs from military surplus.

I use them and when the surplus runs out the originals still around for ridiculous money....

Speakon or Powercon

there is variety of types ; choose on

they're good enough for XS-es

Thanks guys
are these the ones Pack of 4 8 pole Speakon connector with a metal latch lock for speaker cables. Can handle 8-16 mm cables.

i presume 8 pole means provision for 8 different wires/connections

Speakon and XLR both make good high current multi-pole connections.
But, the problem is that these are normally used for other duties.

How would you ensure they are never connected to the wrong socket?

No. Use something that is different than what your mains power is. It's the only safe solution.

IEC comes in a big variety, you don't need to use the same ones as your mains. I didn't.

My mains on the left. My DC cable on the right:

hi all
i would use the standard iec recepticle/power cord for power in to the power supply case and the speakon connectors for power out to the amp case

it would therefor be impossible to mix up the connections

Just read Tinitus,s thread
exactly as was suggested there
also should i keep the rails for each channel seperate?
i,m using these power supply,s
http://www.aussieamplifiers.com/psu.htm
they have 4 seperate rails so if i,m correct i can use the one transformer and still have a sepetrate rail for each channel of the amplifier

..... and the speakon connectors for power out to the amp case

I don't think Speakon was suggested
and the Powercon are for mains voltage

but you might be able to use Powercon safely, by 'reversing plugs'

meaning, a powercon cable would have normal mains plug in one end, and a Powercon female at the other end
and the box will have a male chassis plug mounted
thats the mains cable

so if you amp box have a fixed output cable with a male connector
and your power supply output have female chassis plug

this way you cannot connect any other way than the intended

hope I got that right 😛

with one hatch
a Powercon female chassis plug is actually intended to be used for mains out from a box

For about $10 a set a nos ITT/CANNON/AMPHENOL is my favorite.

If you can stand the vintage industrial look its a great connector.

An externally hosted image should be here but it was not working when we last tested it.

guess what's this ......

 

[tinitus]

not really sure like(trust) the internal construction of powercon/speakon for high power DC
I think it was why I disregarded it from the beginning

ever dismantled properly made one ?

 

[tinitus]

found a product called SOURIAU

 

[Zen Mod]

these are veery good looking

Gday all
Thats the speakon 8 pin i beleive Mr Zen and just what i was thinking of using

Tinitus i,m going to be using the plugs and making my own leads so i can make the umbilical totally different to the mains power cord

The speakon connectors i,ve looked at so far are rated to 30a continuos so will be fine

by 'properly made one', I suppose you mean how the cable is mounted

I was thinking of the way it makes contact when connecting
