Sound very acceptable to me. I have 4 MRC20 power supplies with 3 DC Masters and 3 Quantuum Engineers and I have wired in a selector panel using rotary switches. You can select the MRC 20, DCM, or the QE outputs, then that feeds the selector panel of rotary switches that control which power supply feeds which track. I have a 4 track mainline, run 4 trains at once or any train anywhere, I have to acquire 1 more of the DCM and QE to complete the installation. Good Luck!
Does anyone know if it is possible to wire the BLI DC MASTER to two (2) power packs at the same time using an A-B Switch to assign the controller to the correct power pack?
