The layout is powered from six 240 Volt AC power supplies delivering a number of low voltage outputs for different purposes:
|1||15V DC 6A SMPS||DCC Booster||All track|
|2||12V DC 5A SMPS||CBUS modules and accessories||Michel Delving, Hobbiton and Rivendell|
|3||12V DC 5A SMPS||CBUS modules and accessories||Buckland, Bree and Staddle|
|4||16V AC||CBUS modules and accessories||Grey Havens|
|5||16V AC||CBUS point modules||Michel Delving, Hobbiton and Rivendell|
|6||16V AC||CBUS point modules||Buckland and Bree|
The 15V DC 6A SMPS supplies the DCC booster rated at 5A that powers all the layout track. The MERG CBUS modules operate from a 12V DC supply with the exception of those operating the points, which require 16V AC. A new, 12V DC version of the point module is available but had not been developed when the conversion work started. The 12V DC supplies also power ancillary circuits including lighting and other scenic effects.
