I have a number of H0 MTH engines with P3 DCS/DCC. I have never used DCC but am used to DCS. DCS needs about 16v to get loaded and running. In DCC, do they also need the higher voltage?
thanks
Steve

"HONGZ" stands for HO scale, N scale, G scale, and Z scale.
Post your non-O scale stuff here!

This is from an MTH HO manual. Looks like as low as 6 and as High as 24.
When I ran my O scale MTH engines in DCC mode I used 11.1v and 14.8v batteries very successfully. So that might be an acceptable range.

Again, I'm by no means a DCC expert, but the answer to your question might be dependent on the needs of the DCC equipment you are using to run your DCC engine, on how large your layout will be, and on how many DCC equipped engines you plan to run. I remember reading something about DCC "boosters" (more amperage") sometimes being required.

the power supplies for most DCC systems are 15 volt AC. Boosters with power supplies are used on larger layouts to divide up the load (amperage) most DCC systems are 5 amp (NCE and Digitrax also have a 10 amp system) so splitting the layout up into more than one section splits the load. The DCC signal is passed from the system to the booster's via the control buss.
Most HO DCC systems have 15volt power supplies but output 13 volt AC square wave about 5 kHz

Those are the instructions for running under analog, not DCC. I think Steve was asking about using DCC.

^ I think that's the answer Steve is looking for.
Based on my use of DCC (for N and HO, but not MTH O scale engines), my thought is that the best way would be to hook up the entire DCC system - it will provide the desired amount of power (usually 14-16v AC).
Our large HO club layout uses NCE DCC. We have one MTH HO DCS/DCC Challenger that runs fine on the NCE 13v DCC
