DCC To DC - Accessory Power Supplies
These circuits can be used to supply low current DC accessory circuits by tapping into the DCC track supply Bus. This might be done if a regular DC supply was not available and the power required by the accessory was small. The unregulated power supply circuit could be used to supply power to the Automatic Grade Crossing circuit on this site. WARNING - Accessories supplied by these circuits must not share common electrical connections with circuits connected to other power supplies, either DCC or AC powered. Any inter-connections with other circuits should be through optoisolators or relays to prevent possible short-circuiting between the supplies.
