Dual Power Supplies for Layouts

Written by David Head. Posted in Power Supplies

At EMRC we use two battery chargers ( with modifications) to power our trains. We use a split potential power system that means -12V DC 0V + 12V DC. In effect you are using one transformer in one direction, and the other for the reverse direction.

See the power supply picture for a example of a split power supply. See the second picture for an overall diagram of the layout's wiring.
