Product review (4 stars): Easy to install, works well
I bought this item so that I could use low voltage control to enable and disable my oil-less air compressor. It is easy to install. My air compressor draws about 16 amps at 120VAC single phase. So far this solid state relay is performing as expected.

It does say it needs a heat sink. My air compressor only runs for maybe a minute or two at a time, so I haven't noticed any appreciable heat output from this device. I used some heat sink goop on the back and simply mounted it in a 4" square metal electric box that had a smooth back; that seems to give it a bit of heat sink.

I used a spare 4.5VDC cell phone charger with the end cut off as the DC supply for control voltage. It seems to be working fine.
