Help with Nichia Nubm31

[ProGamer923]

Hi, I'm somewhat new to electronics and I wanted to set up a Nichia Nubm31. The picture, however, does not seem to make sense to me. Is this picture saying that I have to connect the pins to themselves with the input and output pins being connected regularly? I have been looking online for months, but since this diode array is somewhat new, and was made in a different country, I can't seem to find a whole lot of information about it. Any help would be appreciated, thank you!

Yes, it connects exactly like in the picture. In this case, it is so if you use one driver for power supply. I use two, you will have to make it like in the picture. One driver will power both rows of diodes, and the other will power the other rows.

Be very careful with the array pins. They are very fragile and can be easily screwed up. You use soft silicone cables because if they are hard they can twist the pins and break the threads in the array. That's why I use the board as a base, having previously disconnected all the contacts between the individual pins of the board.
You can use this 600W for power supply. You will need two drivers for every two rows. You need to set them up beforehand

You can also run the diode strings individually like I did so you don't have to use a boost driver and just use a linear regulator.

Either way will work, just depends on what you want to do

I was thinking about using this driver:

If I'm understanding you correctly you should wire the pins as shown in the picture if I plan to use a singular driver. Otherwise, I can hook them up differently if I use multiple drivers. Real quick, what is the benefit of using more than one driver?

Yes, if you use this driver you can connect all the pins exactly like the picture. I didn't recommend it to you because I recently received two, but they turned out to be a bad batch and couldn't power the array. There is information in my NUBM37 thread about this driver. I use the 600W ones because they work very stable. In this case, you need two of those 600W, because you cannot power the array with one. They put out about 60-64V, and you need a lot more.

New project with NUBM37 125W

I received a NUBM37 125W laser array yesterday. First I rewired it from the board to remove some of it and break all the circuits with the pins. Currently, each pin is independent. Previously, 2-3 pins were connected and making a connection. Now everything is broken. I'm using the board for...

Okay, sweet! Thank you kindly, this has been very helpful!
