    Hi all,

    I've been looking for a 24V, 8A power supply for my booster and can't find one. I plan on having it run a turntable, about 30 switches, and my yard. My question is, do I need 24V, 8A for a medium sized N scale layout? I can find 24V, 5A, or 12V, 8A. Any recommendations?

    Thanks in advance!

    A number of options here....

    The stepper motor on my turntable is set for 1 amp. How are your switches controlled? Mine only take power when thrown. You could run a number of locos on a couple amps.

    Is there a reason for 24v? My table uses a stepper motor and runs on 9 to 42v. The servos for the turnouts need 5 volts. The Arduino's need 9 and I have LED's on 5 volts. The turntable controller runs on a 14.5v power supply brick (had it) and two very cheap buck converters drop the 14.5v to 9v for the Arduino's and 5v for relays and the hand controller.

    Also 8 amps at 24v is the same as 16 at 12 volts, a lot.

    I got a 24V, 5A supply. The yard and station are isolated and it works just fine. The next step is to figure out how to connect the turntable to the booster. It's an older version of the Walthers 130' turnrable. I don’t have a problem with powering the turntable motor separately, but I want the rails to carry the DCC signal. I've seen differing opinions about using the control box vs. programming it into the DCC controller.

    What I don’t want is to have the bridge track run at a different speed than the turntable lead.
