id love to get my hands on some leftover transformers and whatnot, variacs, etc

This is the biggest one, which I got yesterday. I've got more smaller ones out in the garage.

It's big, haha.

The metal (iron or steel?) is over 5" long and it's surprisingly heavy!

yeah pretty good size, dont fuck with it until you have a very good understanding of electricity it can be dangerous

whats it rated at? id like to get one about 10x that size.

im pretty sure its iron ferrite because it has to be magnetized for it to work

I was going to plug it into the wall and see what it could do //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Not really sure what to do with it, but I figured it was worth saving from the dumpster

i wouldn't even touch it myself, i need to do more research before id be confident in my ability to wire it up to a 120vac source with multiple phases. the wiring may be straightforward, other nuances may not be

only takes one slipped tool/finger and you're dead. it's a little different than low voltage DC

True. I could use a circuit breaker inline with the power cord for more safety :shrug:

I'm pretty sure I know which wires go into the wall. I know which wires are 12v dc positive. Not sure about the ground connection. Was going to use a miltimeter to figure out what everything was //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

We're on the electricity unit in physics class and were talking about transformers the other day. My physics teacher is also a college professor and a smart guy, so I brought the transformer to class today. He said there were either diodes within the wraps, or there were diodes on the external circuitry that I didn't save because that changed the output to DC. I knew about diodes from learning about alternators and how they change AC current to DC. However, before class began he went more in-depth with explaining to me how diodes worked. They're less of a mystery to me now, but I still have more questions to be answered.

Well, I'm going to go to bed. I've got calculus at 8:05 tomorrow morning. The test is on Friday and I still haven't started the review //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif some stuff I just don't get //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

haha back on topic..How do you think amps like the FSD 2600 will hold up at .5?

Thanks, lol.
Besides the obvious benefit of earning money, working at the battery shop has given me lots of good experience and knowledge.

Also, I get quite a bit of free stuff, haha. I've got a ton of jumper cables that were going to be just thrown away, some transformers, circuit breakers, plugs, miscellaneous parts, and some small free button cell batteries. Can also borrow tools like the hammer crimper and heavy duty battery charger so I don't have tom buy them!

like batteries are a bandaid? hehe

I wouldn't bank on it. but honestly it depends on the coils and the impedance rise of the alignment..

what the **** are you doing with a ballast transformer? lol

I used to think that. Now, not so much. Yes alternator power is vital, because that's what's actually supplying the power for your whole system. I would recommend getting the biggest alternator you can and then adding batteries to finish it off (not as just a bandaid)

Pulled it from a power supply at work that was getting thrown away. The power supply just had some blown FET's, so I think the transformer should still be good.

Too hard to say with the FSD. It is a cheaper amp for its size, but from a reputable buildhouse. Would probably do fine if you don't clip it a bunch and spend the money for a high output alternator!

you can have a primary battery supply with a charge on it. its fine, but i dont typically suggest it because of the duty cycle it can present on the alternators. in this case as long as its not dropping past 12.9 or so your good to go..

whats the winding ratio on that transformer?

Yeah, I don't push it below 14v.

Not 100% sure what the winding ratio is. I know it converted 120v to 12v, so I'd assume it's 10 to 1 based on the transformer lesson we had in physics class

that *****. looks like a multi tap.. too back you can use it..lol

NVM its not a multitap. *****.

There are multiple wires coming off, so I'd guess that there are other windings inside that produce a different output voltage

i see a input hot/neutral and the outputs are obviously the larger gauge wire is you low voltage side. i see a black(ground) blue and brown.. **** test the coils windings..

what power supply was that it had to have a bridge rectifier to turn it into DC.. you should get you a lil side project going.. lol you could bump you voltage up to 120v run some much smaller wire then know it back down to 12..
