Solid State Relay Input Circuits

[@cindystewart66]

I had been looking for an explanation of the input to an SSR for a long time. Thank you for explaining it.

[@juliocabrera3191]

good work friend, is the first video that places the internal diagram of a commercial ssr. I congratulate you

[@electrucs219]

Thanks you Lewis for sharing this useful information, given with a very clear explanation.

Its the best solid state ac regulator congrate Mr. Levis,ur explanation & practical, theoratical wonderfull is it can use for 1 hp motor inductive load, starting current 12 amps ur feed back appreciated

[@xavierr4508]

I've just found your videos. They are great, congratulations!

The ssr40dd shown at 1:46 is a CMOS type fo DC control. Triac ssr type has a DA suffix instead of DD.

[@LewisLoflin]

Right it's a DC relay. You don't use SCRs or Triacs for DC.

[@SharifKhan-kt3hq]

Very good example

[@electronic7979]

You share very useful information. thank you

[@dalenassar9152]

Thanks Lewis, So on the input of an SSR that reads 3-32vdc input, am I correct in assuming, that with a typical SSR, you do NOT have to use an input resistor...just applu 3v to 32 VDC directly with NO input resistor? (I will be using 12v to 24vDC to drive the input) I HAVE ALWAYS WONDERED ABOUT THIS!!!

[@LewisLoflin]

That is correct.

You are my best master thanks a lot for sharing this

[@ayhamalrefaei2613]

Thanks for sharing this information

[@Yousef-bg9ky]

how did you maintain 1.85V across the collector and excess current is not entring to the photo diode rather than going to the emmiter

[@LewisLoflin]

Leakage current.

[@Yousef-bg9ky]

@@LewisLoflin what about the voltage then.. cuz even with the drop voltage doesn't reach 1.85V .. thx again

[@LewisLoflin]

Build the circuit and make some actual measurements. Not simulated, real parts.

Thanks Lewis

Can I use a solid state relay to activate ignition coil in a model spark ignition engine?

[@robertfournier947]

Clearly explained

WHAT IS THE PURPOSE OF D1 IN THE REGULATOR

[@LewisLoflin]

Connecting it backwards.

[@davidluther3408]

@@LewisLoflinIS THAT A ZENOR DIODE?IF IT IS THE SYMBOL WRONG.

[@LewisLoflin]

@@davidluther3408 It is a rectifier diode not a Zener.
