question on track voltage

(1/2) > >>

nortoneye:
Just wondering on what ideal track voltage is for RP...at our club layout I have significantly more issues with dead spots and stalls than my Digitraxx colleagues.  HC-1 indicates track voltage under that dips under 13v.  This is with clean track, truck wheels, etc.  Not sure if our layout requires a booster or if KAs would solve the issue.  I appreciate your input....hoping RE comes up with a KA of their own design.  I do have a single K-4 that I have not installed yet, wanted you all to comment.

As always, thanks for the help

14v is the nominal voltage for RailPro. The power supply for the PWR-56 is 14.2v but a little gets lost in the circuitry.

A KA will help of course but the 13v your HC is reporting sounds low for a DCC system, one would have to check the DigiTrax manuals on what the output is supposed to be (not me, sleep beckons right now). The club may need a booster and to make their power districts smaller. If the output voltage from the DigiTrax system is supposed to be higher there could be too much running on the power district for the size of the bus wires they used. This is all speculative of course, I've never measured what voltage the HC reports on any DCC systems track output.

Thanks Tim,

Researching Digitraxx information, track voltage for HO is to be 15v, I will check the voltage at the club each rail to ground to see how close it is to that.  The voltage can be adjusted it says.   A bit higher than the 14v recommended for RP.  Any risk of running at 15v?  If this has been answered before, I apologize.

The maximum voltage allowed for an LM-3s is 18v. The club I used to frequent had a DCC voltage that was never stable. It varied between 9.5 and 15v. Used to drive me crazy but the DCC guys rarely complained. I doubt if Digitrax is designed to vary like that but they couldn't stabilize it. Now and then it worked very well and the voltage was fairly stable. I suppose there could be several reasons for the erratic behavior, but RP wasn't very happy about it.  ::)

You're going to grow old and frustrated if you're waiting on Tim Ring to deliver anything in a timely manner. We've been told of a 'coming' Ring KA for a long, long time. And I'm still waiting on a decent 567 sound file. My suggestion is to install a KA in the manner proven and enjoy running the trains now. The $20 you'll drop is more than worth a year (or more) or reliable operation and you can look at upgrading when, and if, something better from Ring comes our way.
