•Regulated power supplies
Discuss the need for regulated power in garden railway applications
Low voltage lighting and smoke generators
Sound boards and other electronic circuits
Track power needs to be conditioned first by a bridge rectifier to produce DC with a consistent positive and negative polarity
Once that is done a voltage regulator can easily keep the voltage at a constant value
Capacitors can be used to smooth out “noise” and interference
Heat sinks are necessary to dissipate heat
