Inside an SSR

Dismantling a solid state relay - not a cheap rip off this time...
As requested, the link to the one I dismantled is www.amazon.co.uk/gp/product/B...
Obviously I cannot guarantee that these will always be the same :-)

These were a game changer in the 80's and 90's industry for controlling loads like heaters. Never realised you could take them to bits. Very reliable but they do need a BIG hestsink

Very useful video! I now know they aren’t filled with magic smoke! 😂

Really cool I remember when I was trying to fix a Uniden Satellite receiver they had a 3 or 4 pin part that looked like a voltage regulator or transistor but it actually had 50 parts inside It was SS and it regulated the voltage. The old days there would have been a section of 50 parts that did the same thing and took up 4 by 8 inches. Looking at old two way radios from the 70,80, 90s, the parts are huge compared to the parts now that you need a microscope to see

Thank you for this video sir

[@LeeBeasley]

Better than the last one. Any chance of a link to these. I want some to run themoelectric radiator valves so there's no clicking as their on and off all the time.

At 40 amps you better strap it to a water cooled heat sink .

C'est la qualité de la résine qui fixe le prix du relais .

Anybody watching this video has to thumb it up. Purely based on you tore down an SSR for us.

My boi prying with a knife.

I used a dc version of this on my ebike so the 5v alarm circuitry could switch the 84v battery for the motor. bit of overkill as I suppose I could have used an optocoupler and a P channel fet, which no doubt is all that's inside what i bought

[@nitinkumar29]

That triac is most likely a copy of the original so 40A may not be possible. As rule, I assume 1/3 of the usable capacity of whatever printed on chips from China.

Hi, thanks a lot for the video. I clicked on the Amazon link on the description and the SSR that appears is DIFFERENT from the one that your tear apart on your video. Could you correct the link or acknowledge that the one on the link(Heschen Single...) is indeed a genuine SSR with a 40A TRIAC inside? I have seen the FOTEK ones are bullshit and they have 16 and 24 Amp TRIACs inside. Thanks again!

[@nomadicoasis9260]

thanks just got one of these, I wondered what was inside. still wondering how on earth a PID controller is programmed!? I thought it would maintain a constant temperature for my oil filled electric heater. ie. set 27degrees C turn on. boy was I wrong.

[@tiagoferreira086]

google "Ziegler-Nichols method", but there is other methods

[@hillppari]

cheapones wont work with 3volts as the voltage drop from the status LED makes it drop under and not work

[@britishtechguru]

I have one similar to that. Works well as a 12v DC relay. I'd forgotten I had it, to be honest. Right now I'm using two mechanical relays to run my 120v AC 20 foot long morse code flashing penis.
