The MOST POWERFULL 12V PSU EVER...

[hipro5]

HA, HA, HA.........We have "mixed" the two PSUs here.....
Just forget the 1200Watts one in this thread......I'll open a NEW one for it some of these days that I'll have the FINAL PSU here......

NOW 4500Watts PSU.......Efficiency of it will be MAX ~68% (God's willing first).....

ONLY the heatsink of it, weights about 20kgrs....

Thanks guys for the links of the shops....

using a lineair design? I don't think so
I haven't seen shematics yet but assuming that opamps are used for the voltage regulation in combo with powertransisotrs, you can probably bake eggs on warmt genereted by the total quiscent current

Nope.......The heatsink will work aprox. at 38 - 45*C MAX with 2 x 12x12cm DELTA Funs blowing it.....:p
