Has anyone built one of these? I have a PWM on the boil kettle and am looking to try something new for giggles.
I found this unit online. http://www.nuwaveproducts.com/ssrman-1p.htm

I was thinking of wiring that into a box with a random SSR and see how that compares to the PWM that I have.
If no one has done it no big deal, but was wondering if anyone had any experience?

I know very little about phase angle, and what knowledge I do have revolves solely around amplifiers for audio. In that sense, it's important to know phase angles so you know if your voltage rails can handle the pos/neg swings. With SSR's that operate either on or off, I don't see how adjusting the phase angle will help anything since on/off is associated with square waves.

what kind of control are you looking to get out of this?

Just boil control, I think it will work better than a PWM, because I use my controller for temp control in other "heating applications."

My understanding is if you use a random SSR that won't wait for the zero cutoff, you can smooth out the frequency of the off and on. It may not make much difference for just boil control, but its pretty inexpensive and offers more control for about the same money. (More like a stove control.)

Oh it looks like I need to read up on SSRs instead. When you said random SSR, I imagined you reaching into a grab bag and working with what you pulled out.

All you need is one of these http://www.ebay.com/sch/i.html?_nkw=...va+r&_osacat=0

And a potentiometer. It is NOT a typical ssr, it's a modular phase angle control unit. All you need to do is hook the potentiometer across the control outputs, and the ac hot through the other two outputs, and voila, you have a variable control.

Lots more information here. http://www.artisan-distiller.net/php...hp?f=62&t=6079

Thanks Swede! This looks easier and cheaper than the PWM while allowing even better control.

The only shortfall is if you want to control multiple elements or have individual element control. These are well suited to a single element, but once you start running say two 4500's in a BK, then you would need to get a little creative with your wiring.

For my larger control panels, I use PWM because it can easily be manipulated for multiple element control, and each element is individually controllable. Check out my sig to see what I'm talking about.
