Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Starting to clear a path through a lot of stuff under the house when I had to get to the hot water cylinder under the house. Controller broken down. Wire in temp controller. Then unrelated to hot water cylinder found an industrial board having what I believe is an Intronics Inc. power module on a pcb of some size.:

Intronics
SM 300/5-150/12

I believe it is a 240V (there is a fuse 3AG 313 littlefuse, 250V) driven by 240V having 5V and 12V DC out.

Have searched the internet but the Intronics Inc I knew back in the last century seems gone.

Anybody by chance having a power catalogue from them with the SM series?

Hi plover,

I don't have a power catalogue and I know nothing specific about the SM 300/5-150/12.
But I found this https://core.ac.uk/download/pdf/51243018.pdf.

Quote Alimentation stabilis�e �12 V, 150 mA
(mod�le SM 300/5 150/12 de Intronics).

I don't know if that helps a little ...

Regards
Michael

Thank you, it helps. Canada mains power listed as 120V and I could not determine from the pdf if they also use 240V AC. The current large enough to drive a number of OP amps.

Is there a reason you want to replace that specific device? Space/tidyness etc?

5V & 12V PSU not hard to come by if you are forced to home-brew.
