Your prototypes look even more interesting now. Where did you get those car-audio like heatsinks, terminal blocks and fuse holders?
Eva, i think the heatinks are regular aluminum U-girders, nothing car audio spesific. Thr fuse holders and terminal blocks i guess is either bought on a car electronics store or salvaged from a broken beyond repair car poweramp.
The gate resistors are 20R.
Yes the heatsinks are 8mm thick aluminium girders as finding suitable aluminium extrusions are a pain in the butt. These were machined by an engineer to fit the steel plates and PCB. At full power they remain relatively warm after a while +/- 45 deg C.
The connectors are not second hand I assure you. They were obtained from a manufacturer in China that specifically makes terminal blocks. Beats the other forms of connecting power hands down and looks a lot more professional if I may say so myself.
There is nothing in that psu that is not new.

Please, could you tell me how to contact this car-audio terminal block manufacturer or any of its dealers? Please send me a private message in case you feel that posting such information is inappropriate.
Thanks 🙂

I dont mind telling you. The only problem is they supply manufacturers of power amplifiers like Alpine, Pioneer etc. so they have a minimum order quantity that would make your eyes pop out. I managed to get a few samples from them and when I requested a pricelist I was astounded as to how cheap they are and let me assure you the quality is excellent.
If you have a few thousand Euros lying around let me know

Hi Archimedes
Can you post schematic for your smps or send me email, I would like to see how you made under-voltage shutdown.
Thanks, Luka
