Fixing a Biometra thermal cycler
« on: September 19, 2023, 01:16:34 pm »
Hi,
I am sorry, not sure if I am in the right session of the forum, but will try. I would like to repair something :-)
I am also not really very knowledgeable in modern electronics, but did something with it as an hobby before (but this was about 30 or 35 years ago, so other times, and don't really remember much about it).
Anyway, I have an old Biometra thermal cycler that I would like to fix (this is a piece of scientific equipment). The problem with it is that the inlet fused socket is damaged or broken. I would like to find a suitable replacement, but I cannot really understand the information on the label of the socket (so that I can buy some compatible socket from some place). In the PDF file attached I have photos of the broken socket and the information printed on its side. Unfortunately, the original company who sold this equipment no longer exists, and the current succeeding company doesn’t fix these old pieces equipment (I am in the UK).
I would be grateful if someone with expertise in this stuff could give some advise about some compatible replacement.
Many thanks,

That's a fused IEC 60320 C14 appliance inlet, with integral line filter, and what looks like spade terminals for the internal wiring.  The form factor is pretty standard, so just about any will do if it has the same style mountings, and the fuse below the connector, and an adequate current rating.

Search 'AC power entry module' on Mouser or DigiKey.  I found a few different options for you that should work fine if it fits the chasis frame.  Just stick a 2A fuse in there instead of 6A.  If this one doesn't work for you, just make sure whichever one you find is rated for your mains voltage and amperage.  Don't be concerned about matching the EMI filter circuit exactly.

I work as a lab instrumentation engineer for a biotech company so I have fixed my fair share of thermal cyclers  :)
