DCC Power Supply

Model Railroader General Discussion (Model Railroader)

I plan to buy a Zephyr and use my 2 MRC Tech II Railmaster 2400s via the jump ports as throtles. I asked the question on another board if the AC output on the MRCs could be used to power a PM42 auto reverser. The answer was, that it may cause a feedback and it was suggested that I purchase a wall type power supply (wall wart).

Is this the best route?
If so, will I need a PS for each add-on to my DCC system?

How many of these small wall type PSs do you have on your layout?

Dave;

Here are some very reasonably priced:

in particular the ACTX-186

Snake,
The PS42 divides the output of your booster, for autoreverse sections and isolated sections. The power supply comes from your booster. So you will only need power supplies for each booster you add.Dave
