I am pondering on using a switch mode power supply with a solid state relay, bit is that a good idea?
My concern is the solid state not disconnecting it completely, and maybe allows the power supply to be powered up a bit.
I have tested this with a smaller switch mode power supply (500mA wallwart), and with a LED on, the LED is still lit after turning the solid state relay off.
But will something like this scale up? My plan was to use it with a 30A switch mode power supply for my 3D printer, but when turned off, it should be turned completely off!
The reason for the solid state relay is that it uses so little power to turn on, and the mechanical using more power than I got avalible on the printer without the external power turned on.
