HISTORY:

Imported from an international research laboratory (by ship!) as the equipment was being disposed of due to the previous establishment upgrading their equipment in the early 2000's. This is yet another very nice item of industrial equipment which I have decided will become an organ donor.

It is the MATSUNAGA (Yokohama Japan) Frequency Converter, intended for laboratory use and providing up to 240V AC at a user adjustable variable frequency. Not only that, the AC voltage output could be varied across a wide range AND the user could set current limiting, so it could alter all three aspects of the AC output wavefrom, frequency, voltage and current limiting. I actually fired this gear up and it was working great but oh dear! What to do with it? Sure you could put up on the workbench but at that sort of weight it needed a lot of space and a good solid workbench. I decided a while back to offer this equipment as a complete unit "elsewhere" online for a while but there was no interest at all so I pondered over what to do with this equipment (to keep or not to keep) but it had a few things going against it.

As a complete unit it was EXTREMELY HEAVY, over 50Kg, which means that my arms are now 30cm longer from lugging this beast around the workshops! ... but more seriously, shipping would have been difficult to ensure safe travel AND very expensive. It also had other minor cosmetic issues because it is not easy moving such a monster around so it suffered scrap marks on various places of the all steel casing.

So, the "donor operation" has begun and here is bunch of the internal high current interconnect leads (fully described below) .... all use the same Sumitomo cable and are high current, high voltage, high temperature capable.

SUMITOMO ELECTRIC INDUSTRIES (JAPAN) - High Current Interconnect Leads With Connectors

Made and completely assembled in Japan

With the exception of one lead, all have a bright White sheath

Most leads have connectors fitted, these are all crimped and insulated fittings

CABLE SHEATH PRINTING:

CSA TYPE REW (XLPVC) 600V FT1 SUMITOMO-Y E41106-Y AWM 1431 105C VW-1 AWG12 -F-

Sheath is 5mm OD (measured)

Multi-strand core (not solid) is 2.5mm OD (measured)

Semi flexibility, not stiff like a solid copper core and reasonably easy to route the lead from point to point

Where the lead has a terminal fitted (some don't, the details are below) they are all the same terminal ...

Eye type: 5.2mm ID 9.5mm OD

This 'pack' of leads comprises the following leads ONLY
