Enclosed are links to some off-the-shelf solidstate switches I have had success with. The unit listing last I have used to switch 120VAC/15amp circuits with a Raspberry Pi output.

I tend to buy more than I build if I can. I can't make it for the price.

Thank you for your answer Colporteur,

I'm looking to regulate 0-24VAC with 0-10VDC, not to switch ...

Best regards

Actually, something like that :  https://www.huimultd.com/PHASE-SHIFT_TRIGGER_MODULE/TRIAC-JKKE/  but in DIL form or SMD for low power (6W)

Thank's

The terms used added some confusion.

You are looking to regulate the AC voltage using a triac?

There is a difference between regulate and control. 

Maybe provide some description of the goal of the circuit. "I want to vary a AC fan speed."

Sorry Colporteur, my english is not so good. (swiss french :-))

Actually I know very well how to do it (synchro sawtooth ramp, compararison with the set point and so on).

My question is  : has some supplier build an integrated circuit for this function (ramp building, comparison and triac driver) ? It's just a matter of space saving on the board ... but mainly because I was asking myself about it, and I like to know things, as it is supposed to be my job as engineer ... :-)

For information, the circuit is giving as output  Dmx signal, and a 0-10V signal. I have to add the 0 to 24VAC just for a damned bulb in a button, as I don't want to modify the whole wiring of the bulding.

Anyway, thank you for the time you allready spent for me

Please don't feel you need to apologize for the language challenges. I need to be reminded English is not everyone's primary language for communication. My assumption was you were fairly knew to the site.

Individuals make short posts (i.e. few details) hoping for a quick answer. I found you need to invest in your post if you want to improve your responses.

The E14 Community has members with a diverse range of knowledge. At times individuals assume we know what they are talking about and at other times there isn't enough detail to know what they are talking about. Throw language differences in the mix and it can take a while to achieve success.

There are some pretty bright and talented individuals that participate on the site. They are more than willing to help. The trick is how to avoid the wash, rinse & repeat the cycle of making post after post trying to get sufficient detail to get a response. I have found if your initial post attracts some of the bigger fish (i.e. knowledgable folks) then you will get more activity because individuals follow the big fish.

Describing the ultimate goal in a post usually helps. Diagrams, even if drawn on a napkin are great offerings in a post to achieve success.

I use the site quite often for technical answers and find it a wonderful resource. I value that individuals that take the time to respond.

I see some bigger fish are chiming in. Good luck on your quest.

Hello Colporteur,

You are right : it's the first time I'm trying to get an answer using a forum !

And you are right again : a little drawing will help ....

So ... the basic question was : does somebody knows if there is a supplier who has integrated the red surounded part of this simplified schematic (or similar function, or a part of it, ...) in a DIL6 ?

The T2 - T1 stage is the synchronized ramp building, the comparator is ... comparing, with the DC set-point, and the UJT stage firing the thyristor.

It is simple intelectual curiosity

Actually I'm firing the thyristor trough a pulse transformer, because I don't like the link between neutral and DC power zero, and some other implementation reasons.

Thank you again for your patience, and sorry for my poor english, I don't trust translating softwares ...

Best wishes

Piper
