View Full Version : Wall wart dead after hooking to SSR?

I killed my Ramsey FM25B wall wart stock power supply (not the transmitter) by plugging it into an SSR channel. It died after about 10 seconds of being connected to a channel that was 100% on. It never switched off or dimmed. I did have a C7 bulb on the same line just to be sure I had enough current....

Anyone successfully run a wall wart off a SSR without killing it?
Anyone else fry a wall wart with a SSR?
Anyone else kill anything using a controller?

Thanks,
Dave

I have to say up to this point I have not broken the homicide cherry yet. I have not even seen magic smoke yet.

Actually now that I think about it I did have some strobes go out last year and they were controlled by a ssr. I also had water infiltrate the bridge rectifiers on some "sealed" "outdoor" led strings that caused some issues for me. They were on ssrs but the water was the deciding factor.

I guess I am a MURDER after all!!!!!

I had a wall wart for the 24volt strobes.
but it died too, only 3 volts out,
and I wasn't doing dimming,
just on-off.
Thought maybe just a bad wart,
but . . . :cry:

Not good..... as a rule, I guess wall warts shouldn't get hooked to our SSR's. I need to look at the AC output of our SSR's with a scope. I bet it will look pretty ugly! Perhaps something resembling the AC equivalent of a square wave?

I used a wall wart with puck SSR and I it failed after about a week.

xmus, please get back to us on what the output looks like! I too am curious.

Thanks Wake,
I was just about to use a puck to control the wart.
Well,
I guess it's onto using a relay controlled by the SSR,
maybe with a light parallel to it to provide a lower resistance.
Could be the SSR's don't like a small load.
And many SSR's are listed for resistance or incandescent load only.
No inductive loads!
