THEORY on TPU energy scource

[Magluvin]

Oh. Sorry. Those pics are from the net.  Im looking into variacs to buy.  May not have till next week or the week after.

So are they all decent for this project as long as they are 240v 2A?

Was looking for Malpin but none on ebay and looked at the Malpin site and put a search for variacs but nothing came up for that on the site.

Will be back in a couple hours to respond to the things you posted. Again, sorry, I should have specified that those pics were from the net.yahoo image search.

I was very very frustrated last night when I wanted to post them. OU.com was only letting me into the home page a couple times and when I finally got to making the post, OU was out again. Spent a couple hours trying. Sometimes it makes me paranoid.

I use a voice to tex system and it takes time for it to start to function without error ! Sorry if your heads have been programmed by the self-oppugnation of the extremals in the delirium one has only to see that a computer needs to compute in order to function. As yet they still need me to do that for them !


Now I see the transformer and yes not easy to make ! So plug it in and let me see what cap bank you have ready ? There are some simple tests to do that will completely surprise you.

I want you to use a step-down transformer 12v 2 AMP if your variac is a 2 AMP ! And try and get some thin 0.10 nickel wire as a load ...... Its best to set it out in a straight line for now and you will use it as a variable load.

If you, for now, have a 1F 12V DC capacitor that's ok to start to test your variac as the collector !

You will need a current metre to check input and put and that is the very basic set up .

You're going to go for a 2WATT INPUT FOR A 40 WATT OUTPUT with this setup and don't question the results as you really just need to move into an off grid situation.

Place your variac on a table 1 metre off the ground as there are some things you will need to study as I want you to drop the output wires 2 inch off the ground and don't let them short out !

You will need to use 5 different types of out-out wires and just do the same thing and test each set for volts only ! The gain in the out will show up slower with thicker wire than the thin wire so let me know what you will be using ?

Understanding ground connections is an important and different thickness in the wire does something not listed anywhere and you just need to take not of it for now !

Don't hurry and don't blow the transformer ! You have to have a 240v AC 10 amp grid supply or you are going to do things in a different way .

Is this ok with you ? I am sure you can do it but don't start messing around with all kinds of loads ! What you're looking for can simply be lost if the variac begins to heat up and is why its best to start with a new one ..... 

Parts

1 NICKEL WIRE

2 1 F 12V DC CAP

3 5 DIFFERENT OUTPUT WIRES 1 METRE IN LENGTH 

4 1 NEW VARIAC 1 AMP OR A 2 AMP

When will you have all the parts ? and please provide a time plan for your tests so we can all know when to expect the results .

Rember do not use your variac for any other purpose not even once ............. It has to be brand new !!!!!

Hey S9

From your last post, the paranoia thing is just the fact and timing of when I go to post on some subjects and hit post, the page sometimes goes to Page Not Available. Then I try to go to the home page and it is Not Available either. Then I try the site on my cell phone, not logged in, and it is fine. It has happened quite often when I post on subjects that seem possibly touchy. So I just feel it is odd considering... Not that the site is a root cause. Weird.

I do have a 1F 12v cap. Actually they are rated to 20v max, but are used to stabilize car audio amp power inputs. You had mentioned that they should not be leaky as in somewhat self draining. But these tend to be such, and more so the higher the voltage gets to the rated value.

Im not sure what I should do with the cap here, as I believe you stated it was to be of the same rating as the transformer earlier.  Are we going to input 12v into the variac from the 12v transformer? These 1F 12v caps are dc. No diodes?  Can you provide a simple diagram of what we want to do, or do you want me to wait till I have all the parts? Kinda anxious to get my mind on what I will be doing. But I will wait if need be.

You stated that I should not use the variac for anything else before hand. Would testing the variac at the manufacturer before boxing affect the do not use clause you have given? Just thinking. Or like you said, we just dont want to get the thing heated up in any way? Just wondering what problem would occur to the variac if it were used in a normal testing before hand. Like is it that we dont want to cause any possible heat expansion of the windings, or cause harm to the core. just interested in details on such as we have a little time to talk of these things before I get the parts together.

On the subject of the 2 wires that reach to the distance of 2in off of the floor...  Im wondering what you were saying about grounding. Like does it matter if the floor is concrete, tile or actual dirt ground like outside?  Is this 2in from the floor something that is in relation to the ground pin on the plug input of the variac? 

I dunno for sure and my mind is just trying to figure out your descriptions.  Some diagram would put me at ease.

Checking out RS Components site, in the US they are quite expensive. In the range of around $300 to around $2000.

Found 1 on ebay for $100 rated at 240v 8A

Ok, gotta get some sleep. Thanks

Nut cases do not normally follow rules Chet,and it seems we have another one here.

MAG if you're in the USA its going to be a bit of a problem as you need the 240v AC supply to set up the 2amp variac ! 8 amp can be quite difficult as you will need to magnetise the core so you get the 330v AC reading.

To isolate the TPU effect you have to set up the variac in such a way as it will hold the charge when switched off ! Or you will need a good cap bank and an inverter to stand a chance to get off the grid.

Hey S9

Just wondering.  Why does it have to be 240v in and looking for 330v out? Are these numbers critical to get the job done, or is it that you havnt tried with 120v with a 120v variac? We do have 240v here in the US. So is it that yours is 50hz and ours is 60hz? If so, is there not a work around to configure it to work here, or are we at a complete loss in the US for such a device?

In your depiction, is that just a setup to tune the variac and then move to the next step?  If you dont mind me asking, what is the deal with the 1 meter high table with the wires hanging down? I would like to understand these things if anything.

thanks
