Increasing amps for a DCC system

    Would it be possible to avoid the cost of a larger power supply by paralleling smaller power supplies into the dcc controller? I have a 5 amp 12/volt Radio Shack power supply and an MRC prodigy DCC system with a 3.5 amp power supply that puts out 16volts.

    WOuld the voltage difference be a problem as long as the additional source is at a lower voltage?

    Unfortunately a bad idea. The voltage difference between the two supplies has to be accounted for somewhere, it is going to be in the wiring between the two. Since the resistance in the wire is small, the current is going to be high, and something is going to go poof:mad: ! There are situations where you can parallel supplies, but they need to be closely matched, and it has to be done carefully.
