Wow! That’s freaking awesome Dave! Thanks so much!!! The original schematic (in PDF format) showed he used a G6RW for the relays but when I ordered the kit, it actually came with two JS12N-K. I have the 15 volt power supply.
If I understand this correctly, the relays are what provides power to the UV LED boards. There’s 12 of them, 100mm x 100mm each. Essentially, you daisy chain them together to get one big top board and one big bottom board, each 200mm wide by 600mm long. There’s 32 LEDs per board. Do you think using a 5 volt relay would be enough?
I have a basic understanding of relays. They’re essentially a switch, right? So a 5v relay can handle a maximum of 5 volts, right? I really appreciate all the help you’ve provided. It’s great that I actually understand parts of the circuit. Still get a bit confused with the transistors and the relays though. I really struggle with transistors. I’ve read a lot about them but the documents are really confusing. They talk about holes and things like that. They talk about how they can be used as a switch or an amplifier. NPN, PNP, emitters, collectors, bases and all that stuff, just a bit confusing.
