Has anyone used this? It seems pretty universal from a power input standpoint as it appears that it can connect to the accessory posts on a transformer. I’m considering using it for some streetlights and a few other LEDs to be turned on when it “gets dark.” There are some other versions for sale as well.
Bob, couldn't find any picture?
What's it do? Why the electronic components? It's obviously more than just a terminal board.
Ultimately, that is my question. It appears that it allows an input of various voltages and output those to either 3 or 12 volts. There are also some connection points labelled 1 to 4. It seems that it should do more than just distribute different inputs to 2 alternate outputs?
