Great read. Question, what about DC applications?
Background:
I run both ac and dc on an old school conventional two rail pike. Each power source is attached to one end of a d.p.d.t. toggle. The center toggle pair goes to the posts on an MTH terminal board which distribute either ac or dc to blocks around the layout.
There are four major branch lines totally separated electrically. So there are four pairs of ac and dc power sources feeding into four MHT power distribution terminal boards.
So I can run conventional dc on one branch line while a PS-3 is on another branchline.
All branch lines converge to a interchange yard.
Application questions:
I am guessing a TVS connects each end pair of each d.p.d.t. terminals with respective ac or dc TVS devices.
What TVS for dc?
Is there a multi use ac&dc TVS to use for the MTH terminal board posts?
If attaching both ac and dc TVS do they play nice with one another?
In addition to the main panel there are also 7 other towns or yards around the 2 rail layout each with fully selectable ac or dc option.
Main panel:
Tape on power pack controls same color tape on schematic. Other packs adjacent,
White, red left side & black, yellow right side tape above toggles above the Z-1000s flip ac and dc.
Typical of town power:
There are also some individual 3 rail ac only ZW & Z-1000 routes running at different levels which I will treat as recommended earlier.
