DC Circuit Breakers

[Ed Kapuscinski]

Doing further work on my control box for BANTRAK and realizing I should include some circuit breaking downstream of the wireless DC controllers.

The Lindsay throttles that we've been using for ages seem to have it built in, with those wonderful "screamer" alerts.

Does anyone know where to find those as stand alone components?

Hey Ed,
I put together several SAT-7 throttles in the 90's - They were kits back then but was a lot of fun building.  I dug out my manual and located the buzzer part.  It's a EFB-CB761 piezo electric buzzer. Can't find that part any more but Amazon has them https://www.amazon.com/piezoelectric-buzzer/s?k=piezoelectric+buzzerd

If your interested I have 3 SAT-7 throttles I willing to part with.  Let me know if your interested.

Do you know if the circuit breaker part is separate or integrated?

How about these?  https://www.ebay.com/itm/224126511915

I bought one to use to protect my Power Cab when I run it on a battery instead of its wall wart.

Ooh, that's a very good option. I'd love to find an option with the screamer and a remote LED, but that is a VERY solid plan B!

Both of those features could be likely custom-added to pretty much any breaker device which has a short indicator LED by someone with electronics knowledge. Most model clubs have such a person.

Yeah. I could do it too, but I'm a bit nervous when dealing with surface mounted components like the ones on this. I know I could unsolder the existing LED and replace it, but honestly, I just don't want to, lol.

LOL, for six bucks plus shipping, buy a few.  Even if you ruin one or two while soldering, you will learn to finally succeed.  I wouldn't even unsolder the LED but connect (both external LED and buzzer) to the common (either positive or negative - whatever they use) and the "short indicator" signal which drives the LED.  That way both, the original LED and the add-on components would signal the short.

Lol, that is what I did. Although I only got the two I need. I probably SHOULD have gotten more though, duh.

We'll see how it goes and how adventurous I am when they arrive.

Ya know, Ed... that overload thingy I created can do all this, and it has an aux output for another "indicator" that can be anything that will work on a 5v supply.  So you could just hook one of those piezo buzzers to that and Bob's yer uncle.
I can't build them for $6, though, LOL.  Still, if you are at all interested, shoot me a PM or an email.

Lets see how the $6 option (currently in the air from China) works. I'll keep this in mind though!
