Ted S posted:Getting a bit off-topic, but I was hoping to use it to convert our track ~16-19V AC to a constant 18VDC, to feed a radio-control receiver that was originally designed for on-board battery operation. The manufacturer of the receiver warned me that it was designed for a battery source, and very picky about not being subject to voltage fluctuations.
So I purchased some of these modules from the auction I mentioned. They're quite small, maybe 2" x 1" x 1"-- definitely small enough to fit in a loco tender, even with the R/C receiver board in there too. I didn't think much about heat dissipation. But if I heat-sink it to the frame hopefully it will be ok. It just occurred to me that being so close to the receiver, I wonder if it will create radio frequency interference? Haven't had a chance to try the experiment, too busy with other hobbies and holiday preparations.
Well, a linear supply won't be likely to produce RF issues. First off, what is the actual current requirement for this RC receiver? I can't imagine it's in the amps range, so a much smaller supply would likely do the trick. How about starting a new thread with your issue and some details and we'll see if we can help you?
