AC/DC Power reducing “Buck Converter” Installation on model building, to convert wall-mount power pack to AC transformer power. Connect a digital multi-meter to the output end of the “buck” using alligator leads, so you adjust the output and do not send excess voltage to damage the building LEDs. Connect your supply to the AC/DC-IN side

Nov 15, 2020 · LED is an acronym for L ight E mitting D iode. A diode only conducts current in one direction. Which means the LED only lights up when the current is flowing in one direction, and not the other. If you apply DC to the LED and it does not light up, then simply reverse the wires as pointed out above

Jan 16, 2020 · I was wondering about the mixing of AC and DC locomotives in a consist. During prolonged slow-speed/high-current operations, and assuming the DC unit(s) are trailing, how does the engineer in the lead AC unit know and respect the traction motor limitations of the DC unit(s) which cannot endure anywhere near what an AC unit can.

Yes, they all say LM2596. There is also an LM2596T which is more expensive and I'm sure has more functions. You are correct that once I get the regulator set up, it will be a permanent one. I do have a Greenlee multimeter. Thanks

Not quite, this is what I had in mind. Sorry for the scribble drawing.

Aug 25, 2022 · Recently I have been working with my 2 trains on 1 track systems, with blocks and relays. I fixed non operation when both sensor tracks lacked an insulator pin when assembling the train board on installation in the train room and with NO on the tracks, operation is the best ever. I have also finished reading A C Gilbert's autobiography "The Man Who Lives in Paradise". It is …

It depends on the brand of track and how it is installed/wired. Traditional three rail track has both outside rails electrically connected to each other, so that would subject your DC power supply to a short circuit. Check that first. If the outside rails are not electrically connected to each other, your scheme will be fine. Gargraves and maybe Atlas have all three rails isolated, but it ...

Stan, forgot to post back here with the info. Here is the new thread: ITADs and Making Your Own Opinions wanted! Also please add anything I haven't thought of? I tried to ask some questions in the beginning. I'm sure you have answers to many questions that I haven't yet thought of.

In practical reality there is no difference when you are talking an incandescent bulb, they work equally as well with DC or AC, to get the same amount of light out of the bulb you use the same voltage/power. People have theorized that DC will extend the life of the bulb because A/C is constantly changing its direction and that "wears out" the filament (I suspect some of this went …
