Spud, boo-whoo, life is tough (LOL).

There isnt enough time in the day. My days are numbered as the wife is nearly 15weeks with the twins, but i cant complian.

[reknaw]

You may laugh now but week one of you having twins at home is the time I am going to laugh :lol: Your world is going to change as you know it........ That said they are awsome little animals - better than puppies or kittens.

lol she would just yell "DAD" at the top of her voice "there is dog POO in the yard".... lol :D

Hey spud just reading this old thread did you get that controller working did you need a fan as well as a heat sink plate? I was thinking of sending for one to use with a 2200 watt boiler :think:

Cheers Hoppy :mrgreen:

Hoppy,

Spud is no longer active on this forum ;)

If I were you I would use a PSR-25 for your controller, they are a proven & pretty easy to build unit that some members here can help you with 8-)

Okiedokie McStill Have looked at your build in the ammo box might have to go that way ,dont look too difficult :think: at worse i can only have sparks fly out my arse :o :laughing-rolling:

Cheers Hoppy

we have a few guys here that can guide you through it, we'll look after you..... if in doubt give us here a yell 8-)

Thanks for the quick reply McStill :text-thankyoublue: will do if i get stuck :pray:

i know there are a few "cheaper" options than the PSR-25 and i even built one of the triac based one's for about $15 but it was a death trap waiting to happen and took me about 5 hrs of driving around to get the right parts.

in the end i bought the psr and pot from RS-online and it works, it is easy enough to build and seems rock solid

the $100 (max) is worth the investment i reckon

Hi Guy's,

I've just been reading this thread as I am in the market for such a controller for my heating element. I have a couple of questions,

1) is there a DIY section on how to build these things and is the F175-25A filter needed to be used with the PSR-25.

Cheers

[maheel]

see here PSR does seem to be the best and "easiest" IMO

viewtopic.php?f=24&t=516

as for DIY make sure yo know enough about what your doing or get a sparky to sort it out.....
it's not complicated but you need to be safe with 240V

i dont have the filter, not 100% sure it's needed on what we are doing, i tried to get it to interfere with radio but could not get it to effect my old radios
who knows if energex etc can 'hear" it ?

i now have a dedicated 15amp line for my shed and use that but is does go back to the fuse box ?

Cheers Maheel,

Thanks for the direction

I would be interested in designing a element control system with temperature monitoring to keep exact temperature if anybody wants to get in touch maybe we could share the costs as I intend to use the design in future projects for other stills. Cheers

Just a quick mail to point people in the best direction by using zero crossing controls for elements this really stops all the noise and crap that filters try and remove. Controllers can be designed to give very close temperature control by using pid type controls too. I can't believe nobody has built a universal element and temp control unit yet that is cheap and reliable. always fuse you control boxes on the light side if you can too.

How much would this cost me?

I'm not clued up on this stuff but this is my understanding

A simple oven thermostat would suit your described needs?
A zero cross relay will simply switch the circuit on and off, not trim voltage like a leading or trailing edge dimmer/voltage controller?
What do you mean by light side?
