Bruker has no stock any more - if the product runs out of 'Service'. So there
are some left, until these are sold.
Nice to have a picture - so I found the real manufacturer of these boards:
https://www.emea.lambda.tdk.com/de/products/vega
Still alive - you may ask this company for help - may be these boards are on
stock there.
Also I have seen something interesting. You can 're-set' the currences. The
currence has some drift and drifts away over the years.
So the 15 Volts are 13.X Volts real. So there are some potentiometers inside -
so you can move the 13 Volts up to 15.5 Volts.
You can adjust this power supply quite easily. There is also the original manual
for the power supply on the top link.
So you can fix it by someone who knows about the old electronics.
I had the same troubles with my old 'B-ACS 60' - the power supply was broken -
I bought from the original manufacturer a complete new one.
It was easy to switch these units and then the BACS worked again. Bruker offered
me a spare part - with no garantee.
The unit ran with the new power supply several years then, until the unit was
replaced with an other BACS 60 unit.
Yours sincerely,
