Which connector for PSU/chassis B+ supply?

[andyjevans]

We use a lot of the Tyco CPC plastic connectors at work. The prices aren't bad and pins run about 25 cents each. If you're good you won't need to buy an extraction tool

you're quite right to look at tyco - the one above's rated 250v. I need to be looking at about 380v DC. maybe another in the range?

Hi,

Using Amphenol connectors military serie... PT 06 Serie: MIL-C-26482
14/12 for 12 contacts 8 #20 and 4 #16 {Digikey}
1000 Volts AC
Socket: 15 cad$ pc
Plug: 30 cad$ pc

For my SE 6C33C-B separated power supply's
Driver PS is 420V DC and B+ 250V {Stacked so 670Volts needed}

Very good quality, 4 wires up to #16 and 8 wires up to #20

Alain.

Yeah - I have to say that Amphenol is nice. I'm slowly coming round to the idea. Just about perfect for me is this one:

C16-3

14P+E cable plug,4way(18A)+11(8A) C01610I0140021
14P+E chassis plug,4way(18A)+11(8A) C01610C0140001
14P+E chassis socket,4way(18A)+11(8A) C01610G0140001
14P+E cable socket,(18A)+11(8A) C01610E0140021

Cost in the UK is £23 or $43 per lead (4 connectors)

It's more expensive than others, but not ridiculous for a precision product and all the connections I need are in one connector.

But look at the above - ridiculously cheap D connector with 8 contacts rated 750v at 5A. This is very tempting - going to look at others in the range.

second opinion?

Hope I'ts not too rude to bring this thread back from the dead but its exactly the question I've got...

I'd like a second opinion. Ive managed to get some Cannon-6 connectors (part number MS3106E16S-1P and associated socket)

looking on the Cannon site yields:

Contact Rating at +20 °C (68 °F) - 22 A
Contact Resistance - 6 Mohm
Operating Voltage - In case of voltages greater than 50V the connector must be used in accordance with DIN VDE part 410, IEC 60364-4-41
Insulator Resistance - Acc. To VG95319, part 2, test no. 5.12
and VG95210, part 32, test conditions B,
standard insulator material > 1000 MÙ
Test Voltage - 1600 Vrms

These *look* like they are suitable to having read the earlier posts but I dont fully understand the notes on operating voltage...

I want to shift the 300Vac from PSU box to amp I'll rectify etc. inside the amp itself

Can anyone help me out here? perhaps I'm overworried but I'd much prefer a non-crispy death.

Thanks

Andy

I use one of those big metal Amphenol 10 pin connectors on my 845 amp with a B+ of 850vdc and its been fine for years now. As long as the connector shells are grounded I'm not worried. Once things get into the kilovolt range then I'll worry 🙂 Have you looked into anything by Jaeger?

 

[andrew_whitham]

Its probably pretty self evident if you know what youre doing but my problem was that I don't get the quote, "...must be used in accordance with DIN VDE part 410, IEC 60364-4-41",

I was looking for an explicit "use upto X volts" maybe thats in the spec and I can't see it?

The connectors I have very similar to the Amphenol ones I think?

Anyway a picture says a 100 words so...

The problem is that EU regs are moving the goal posts regarding voltage. I've had a number of quite contradictory quotes from Neutrik about their XLR series. for some reason they've adjusted the safe voltage down - seems totally beurocratic to me, but there we are. And the Neutrik speakons are surely capable of much higher voltages than quoted. The people who lose out on all these regs is us tube users - it's annoying not to know what actually is the safe voltage, not just some rounded off figure that satisfies a bean counter in Bruxelles.

Personally I've been collecting the odd numbered XLR series - 4,5,6 pole, plus in all these cases you can add another connector since earth can be carried in the body of the plug. Unified housing so it's easy to make a few holes for them and then select what's necessary, blanking off the unused holes. I reckon these are OK for 300v - particularly the 4 pin ones.

🙂 having just spent the afternoon in th ecompany of RoHS compliant solder I *very* see your point..

If you can get 300v across an XLR then these'll be OK - anyway I'm going to go for it! Guess you have to be empirical 😀
