Using a wall dimmer switch to control ON-OFF SSR relay.. will it work??

[ingenuitys]

Hi, looking for help to control a SSR relay.
Would like to know if I can control a SSR-AA relay with a wall dimmer switch,
I just need the relay to switch On and Off to power a separate PSU unit, as I turn On the dimmer switch.
Will the change of wave as you dimming up or down will cause the SSR to malfunction?

Hope this diagram makes sense

It sounds a really bad idea!, and the diagram seems quite bizarre.

Sorry for the diagram novice here..
The thing is I need to control one of the LEDs PSU unit with the dimmer switch and also switch on the other PSU unit which I don't want it dimming, also the PSU that feeds the dimming LEDs is over the rated Amp that the wall dimmer is rated, that's why using a dimmer controller for the PSU.

You've got no incandescent bulbs (and certainly shouldn't have by now), just dump the unused dimmer and replace it with a switch.

Yes, all my lights are now LEDs but I would like to dim this led lighting that's why having a dimmer

You use an LED dimmer, not an incandescent one, and just feed the relevant LED's via it.

Or just use Philips Hue.

The dimmer switch is just used to send the signal to control the (led dimmer control unit) but I also want it to switch On the other PSU unit without dimming

The thing is the load on that LEDs is greater than the dimmer can handle

No, it won't work like that.

Which PSU do you have? I don't know any PSUs that can accept variable voltage AC input to adjust the DC output.

The PSU output is controlled by a triac dimmer control unit that is controlled by the dimmer switch

Unlikely.

How could I make an On/Off switch using a dimming signal as control? Is it possible

That would be an odd, or at least a very specialized, PSU

It's difficult to answer your question without knowing the details of all of the individual parts of your system, Please post links to all the datasheets.

no... the control voltage for an SSR is DC at a maximum of 32V (minimum 5V), and it's only on or off. the output of a dimmer is AC, up to 120V.... so that would fry the driver circuit in the SSR. and putting the AC terminals across the dimmer like you did in the diagram will only fry the dimmer if the SSR happens to turn on, because the AC terminals of the SSR are the "relay contacts"...
