There's always another way of skinning the proverbial cat.Very perceptive, and yes it is model railroading, in my case HO but I find that when I talk to fellow modelers all I get is this is the way we have always done it.
OK, for anyone following along who doesn't know what a "frog" is in railroad terms, it is a crossing point of two rails; the construction and explanation of which is somewhat involved. A photo is worth a thousand words, so click here:There is a newer device out here that's called the Hex Frog Juicer but is is made for DCC and it is for powering the isolated frog.
Well, the common denominator here is that people are interested in a variety of electronic and electrical applications; and exposure to different types of problems is interesting. However, when an acronym is introduced into the conversation that a person not interested in the hobby may not know about, it is most helpful to describe the acronym(s) that are particular to that venue; otherwise efforts that might be expended on helping with your solution are instead expended on simply looking things up!So we always know what section needs the power reversed but it needs to happen automatically when a short occurs and since the current is variable unlike DCC, that kind of magnifies the problem. Sorry about not being more specific earlier but figured I would be talking to people that might not be into any other hobby than electrical.
Sorry, that is not what I meant.Two amps max but for the most part 3/4 up to 18 volts dc, it is only supposed to go up to 12 volts but most manufactures fudge alot. Hope that is what you meant.
