Car amp smps needed

kissendi · 27th January 2008, 01:12 PM

Dear members,

I would like to buy a SMPS for my car audio amp circuit. The circuit uses 1 LM3875/channel and I would like to use 4 channels (LR Front+LR Rear). Supply voltage is single +50 V. 2-3 Amps should be enough. I saw many posts in the theme, but single supply was not among them. I would pay for a ready one, if someone would be so kind to made it.

Thanks in advance

E.K.

Perry Babin had one a while back. Not sure if he made more than one or if he still has the one he originally made but you could check with him.I'll try to dig up the link.

Thanks the link. This is was my first thought, but before ask him I just wanted to know is there any ready kit or enclosed version.

I believe that there is a bottom plate with mounting feet that goes with that power supply.He just had it off to show the internals
