Doepfer

I bought a Doepfer DIY #1 kit used recently that came with a Digitrax 3A 15V Power Adapter. the seller was using it with 4 84HP rows without issue.

My question is, does this mean the Doepfer DIY #1 PSU is putting out more than the rated 1200ma? is it now putting out 3000ma?

I am hoping to to also use it with 4 rows and would love to have a clear idea of how much power I have to work with.
