10,000w SCR vs SSR

[Lyonsie]

There is nothing wrong with the layout of your box. Nobody could safely answer your other question without a schematic.

I looked in 2 old pcs I've got, and if I understand correctly, I'll need use the power supply, on 240, to use fan out the pc. Is that big external fan cooling the power supply and supposed use smaller fan that's the heat sink the motherboard? Seems easier to just order a 120 fan use it from one of my 120 wired on my incoming 240. The power supplies are and heavy too.

I just got a 240 fan of Amazon for about $12 free shipping

The fans you find in a PC are almost guaranteed to all be 12v fans. You'll let the smoke out if you hook them to 120/240v directly. You can use an old cell phone charger that outputs 12v or less, or as you mentioned, you can buy a cheap fan that's meant to run on higher voltage.

[pointhunter75]

I'm sorry, I left out that part about the 12v. That's the whole point of using the power supply . lol

[masonsjax]

Oh I see. That would make for an extra large controller, but it would probably work. The alternatives are better options IMO.

[pointhunter75]

Well people talk using a wall wart, are taking the plug apart and hooking it up inside the controller box or having plug into the wall to power these pc fans?

[ddizzle22]

My under standing of the wall wart idea is doing it inside the controller itself. But it has to be a 4 wire gfci outlet. I was going to go that route but just bought a 240v fan off Amazon and hooked it up. My white wire is just tapped off in my setup now.

If you take a look at my setup pics here: http://homedistiller.org/forum/viewtopi ... 4#p7425974 look in the right lower part of the pic. I have taken an old wall wart and wired it up to run a 12V DC computer exhaust fan. It's an extra plug and it can be a little annoying but I know its running when I have to plug it in every time...

[pointhunter75]

I think I'll just get a 120 fan. Not really a reason use a 240 fan is there? The Ferrule thing from the blue digital Meter goes on either one the hot wires as soon as it comes into the box Correct?

Are you asking about the torroidal transformer? Yes, you insert one of the "primary power legs" through it (one of the legs going to your element).

The torridal transformer uses the EMF field from the current (conducting in the power feeder) to generate a current in the transformer windings. That current will be proportional to the current in the primary feeder. So, the proportional current then drives the ammeter, or an analog to digital converter to measure the current (and calculate the current in your primary).

Still stirrin I'm using same scr 10000 as rgreen and ddizzle.

[pointhunter75]

Oh ok, I think thinking about the Meter, it ties before the scr right?

[masonsjax]

I used a small phone charger to power a fan in one of my controllers. I soldered directly to the plug and shrink wrapped it rather than wiring up an outlet. Works great.

[pointhunter75]

Ddizzle, do you have a pic of the inside of your box after wiring was complete?

[pointhunter75]

Thanks masonsjax. I wondered about doing that too.

[skow69]

The current transformer can go on one of the hot leads anywhere in the box. The current will be the same throughout. The power and ground need to connect before the SSR, not after.

There are several on the first page of this thread...

[TxBrewing]

What switch are you guys using as the master power switch?
...and is it rated for 220v/30a???

thanks

I saw them but a little bit hard to see where some wires go. I wanted to see ddizzles because it's the exact box I've got And his are closer up but His doesn't have the incoming And outgoing wires in his pics.

Anyone using the 10000w SCR know if a standard 6mm knob will fit?

I want to use a knob from an electric guitar

Should fit just fine... The main variation is whether the shaft is smooth or knurled...

[TxBrewing]

Got all the parts in. Taking them to Lowes to find a box

Got my box together and ready wire. Still would like a pic ddizzles box inside after completion.

[pointhunter75]

Where is my incoming common from the wall plug going to on the dual pole switch? I really need pic the completed box internals.

[masonsjax]

Sounds like you need a book on electrical practices or a buddy that's an electrician. I wouldn't recommend learning this stuff from a pic on the internet, it can kill you.

[pointhunter75]

I know some about it and very cautious. I'll take it to my cousins. He's an industrial maintenance supervisor at plant.
