Re: How much track voltage is needed for N Scale?


Correct, N scale was designed with a max voltage of 12V.  So 11.5V is close
enough and with the decoders you will not see any issues at all.  Having the
11.5V everywhare insures uniform operation.

DCC track voltage of 11.5V for N scale is more than adequate.

Hello list,

I have just rewired our club's n-scale DCC power system. I installed a pair of
PSX-2 units from DCC Specialties to improve the circuit breaker functionality
and to divide the layout into 4 sub-districts.

The command station is a Digitrax DCS100 (not powering the rails) and the rails
are powered by 2 DB150 boosters. All 3 units are set to N scale. Each booster is
connected to a PSX-2 and they are both attached to a 12AWG power buss. All
connecting wiring is 12AWG.

I have measured the track voltage on the buss using an RRamp meter and am
getting what appears to be low readings. The voltage is consistent in all
sub-districts, but only reads 11.5V

Any ideas?
