Hi all

I've recently got my hands on a 175 high current adaptor (thanks Phil), and
am in the process of procuring the connectors to make up the umbilical to
connect to one of my 575's.  There seems to be a dearth of information on
the list (the archives and images files), and even on the web about this
unit.  Seems to be fairly rare.

Does anyone have one of these and knows of any particular gotchas before I
connect this up in the next couple of weeks?  I do have the manual by the
way.

For the uninitiated this beast can supply a collector current of 200A single
family or 100A continuous (at 20V, and  and 40A at 100V) a base current of
12A.  It actually weighs more than the 575.  There are precious few
transistors out there even now that can cope with what this unit can put
out.  Collector dissipation of 1kW...

That is awesome. What wire gauge is used in there?

I'll post some pics once I've taken some.

Hi Craig,

?

I also have a 175 high current adaptor. I too need to find connectors to make up patch cord between 575 and 175.? As yet I have not powered up my 175. Maybe now is A good time to work on getting my 175 up and working too.? Did you find a place to get connectors for patch cord ?

?

Hi Keith

?

The cable plug (Amphenol 165-13) is coming from eBay France and was pretty cheap; item number 140541230954, and the cable socket (Amphenol 165-14) was more expensive and from DTL Connectors in the UK.

?

If you are Stateside, there may be many other and cheaper sources.? Amphenol still make the things, but the new price is just stupid money (>>$100++).

?

The high current (100A) connectors are also still made, part numbers and Suprcon catalog are here .? They are not cheap – around $50 each. Allied supplies them, for example.? Then you need sufficiently butch cable (welding cable for instance) to take the current.

?

Totally bonkers of course – but it just has to be done!

PS The 576 tracer also had a high current plug in option with very much the same spec – but it specifically ran in pulsed mode to keep the unit size small, and to reduce power dissipation in the device under test.
