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|
|2||12V DC 5A SMPS||Michel Delving, Hobbiton and Rivendell CBUS modules and accessories|
|3||12V DC 5A SMPS||Buckland, Bree and Staddle CBUS modules and accessories|
|4||16V AC||Grey Havens CBUS modules and accessories|
|5||16V AC||Michel Delving, Hobbiton and Rivendell CBUS point modules|
|6||16V AC||Buckland and Bree CBUS point modules|
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.
