I spoke to a company today that said a device that did this from them was 7k dollars?

Can I put (8) 12vDc 30amp power supplies together in series to get 96vDc and 30amps?

Assuming that the outputs are fully isolated, yes, you should be able to stack supplies.

If the negative output of the supply is connected to earth ground, for example, the supplies will not stack.

Thank you, that is what I thought. The sellers replied saying that I could not do that without explanation as to why and I had thought that you could, just like batteries as there is no difference.

Do you have any idea where I can find the 24vDc's or the 48vDc's? Let components would be preferred, they need to be 30amp though.

Thanks

yes or four 24's or two 48's.

Depends on what you need it for.

Isolated, non-isolated, regulated, allowable voltage over and under limits.

That sort of stuff needs to be known before anyone can make recommendations.
