I've a question about solid state relays:
Why is there a MINIMUM output or load voltage? I mean I understand why
there's a maximum load voltage, any more and you'll fry the thing. And
I
understand why there's a minimum INPUT voltage, any less and it won't
trigger the relay.
But why is there a minimum voltage on the output? Will they not work
below
this minimum voltage? Because I'm looking to switch a 12V DC load, and
I
don't get why there's a minimum that can be switched.
But why is there a minimum voltage on the output? Will they not work
below
this minimum voltage? Because I'm looking to switch a 12V DC load, and
I
don't get why there's a minimum that can be switched.
If you look at these on Farnell's website, you'll see what I mean:

Most of them have a minimum load voltage of at least 19V.
Does what I'm asking make sense?
Thanks, James.
