A simple rectifier circuit with a regulator that can be used to supply up to 12 volts DC to auxiliary equipment. Note that the DC output is not isolated from the DCC. For a 12volt output the DCC alternating voltage needs to be better than 15 volts. If a 9 volt regulator is used then a lower 12 volt DCC track power can be used. The Inductances were recovered from a switch mode power supply, used to isolate noise spikes from the mains input.
