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

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?
