Electrical Jackpot


So I found this huge thing I am not sure exactly what it is, but weighs around 120 pounds maybe more. It has 2 big transformers, one is bigger than the other, along with a random assortment of other things such as capacitors (not sure of their Voltage/uf yet). Any ideas what I should make? I was thinking an arc furnace or something else.



Pictures are way to big so here are links

Capacitors are 75VDC with 6500uf, Electrolytic Capacitors. the big inductor is 1057A, 11k69

The big 'transformer' is actually an inductor, a heavy ass one. The smaller one is a transformer though.

If there's 3 of everything its probably an industrial 3 phase balancing device.

Cheers,

Just going by the color of the cage it looks like something off of a naval ship. If it's military, then it will operate on a completely different system then anything commercial or residential. Anyway, all I'm basing this on is the color of the cage. If it were olive drab, I would have said it came from the army.

It does use MFD instead of the regular UF abbreviation for the capacitors. It does have a bunch of copper wire, only thing I can figure that would be worth making is to get a ton of super capacitors and make a badass EMP device with all of the parts haha. I do believe it was used for radio broadcasting, what type I don't know I do assume high power though.

There is some components which I have never seen before, when I disassemble it I will post pictures of them all.

I found an old manual for it, and a model number. It was made by Bell haha.

From that link:
Quote:
The voltage regulator, designed to operate on a
nominal +24 and —24 volt dc input will provide a
regulated output of +18 and – 18 volt dc supply
at loads up to approximately 1 ampere.


That is a massive chunk of hardware for a 36 watt power supply!

Looking at the transformer size and cores it looks like a low frequency switching regulator. Basically it takes the 24V input, switches it to AC, runs it through a step down transformer, then regulates and smoothes it again providing the 18V DC output. Added to that a bunch of protection and adjustment circuitry. Crazy! Ancient too.

I throw these sort of things away on a fairly regular basis.

Eh darn. Is that inductor comparable to the ones today? I noticed the capacitors are freaking huge, yet I can find similar capacity/volts the size of my thumb, so they are definitely outdated. But as far as the transformer/inductor goes, I believe they still should be good because technology hasn't really changed that much for them, at least the physical design hasn't that I can see. Copper winding around some sort of metal.
