I had my dcc system only a few days and it burned up. I did not plug it in wrong or have any shorts which should have showed up, I connected a DC power pack to tje same track and loco and it worked fine. any ideas what went wrong?

Is it possible to upgrade the basic 1 amp command center with the 5 amp booster? how does one do this, do you just run the booster to the track or plug in to the 16 V input on the controler? The controler input says 16 V and only 1 amp. Will pluging in a booster  directly overload it or burn it up? I am very new to DCC and just got the system today.
