Default relay behavior

I am designing a 12v controlled power outlet for my amplifiers. Since they draw 20 amp, easch amp needs its own circuit. I tested uxcell SSR-25 DA 25A 3-32V DC / 24-380V AC Solid State Relay + Heat Sink

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1


When 12 v is applied to control side, load resistance goes to 0 as expected. However, in 5 sec, resistance increases to 22 kOhms. This is without any power connected to load side, I am just testing the relay. Is this expected behavior for a solid state relay?

I'm not familiar with this particular device but suspect it is normal. If testing a solid-state device the normal ohms scale will not give an accurate reading due to the way it measures and diode effect (junction resistance and biasing on the junction) use the diode test position on your meter.

Also remember when choosing a relay your amps will not draw max-current normally, only at full power output.

As I recall, a solid-state relay may need current flowing through the load side for it to conduct. Not sure though.
