DCC Power

The CFRR is powered by DCC from Digitrax.  The layout is broken down into seven main power districts. There are three power districts on each level and one for the helix. Each district has a DCC specialties PSX-1 solid state circuit breaker to protect the block. Two AR-1's are used on the layout to handle reversing loops. The upper level uses the command station (a DCS-100) for power. The lower level uses a booster (a DB-100+) for power.

The power supply is a 16VAC 10 AMP power supply. This power supply powers both the booster and the command station. A old computer power supply supplies accessory power ( 5VDC and 12 VDC)  to the layout.

Twelve gauge solid core wire is used for the main buses throughout the layout.  Twenty-two gauge solid wire is used for feeders to the track.  The feeder wires have been precut to eleven inch lengths to speed installation.  The track wiring color code  is red and black. 



Below is conceptual propulsion circuitry diagram for the main control circuits of the layout.


Below is the actual circuit diagram and photo of the actual circuits.


    

I recently "inherited" a few Digitrax PM-42 circuit breakers and wired them up.




Below is the diagrams of the feeder locations throughout the layout.
