I asked today one provider and they have some power source but it takes 4 months to get it! In addition to that it seems that I will have to use a DC-DC converter for the "bridge voltage". I am at lost now...
Does anyone have a resource for a AD-DC dual power converter that receives 110 v and provides +V COM and -V? any advice?
I believe Hero999's is for something like this? (sorry I didnt understand magnatro's )
