I just finished building my 240v control box with a DSPR320, 5500 watt element, using a Leviton 3032 switch to allow power to the SSR. I have a 240 LED indicator light wired to come on when the SSR is on. My problem is that as soon as I turn my switch on the LED comes on and I read 230v across the SSR, even with nothing hooked up to DC side of the SSR. I've tried three different SSR's and all three do this. Should I be getting power across the SSR with nothing on the DC side? The odd thing is, when I do put DC power on the SSR to activate it, the LED on the SSR turns on and my LED indicator light gets brighter, but my voltage reading drops to near zero. To say I'm a little confused by this is an understatement. My understanding of how this should work is that there should be no voltage across the SSR when there is no DC power to activate it. Then when I do apply DC power my LED indicator light should come on and I should read 240v across the SSR.
Is my understanding of how an SSR works completely wrong?
