Power supply for Thorlabs laser
I tried to power the ThorLabs ULN15TK with a UX4 EXCELSYS power supply. It seems as though we have the XgF/Xg8 powerMods installed, each with a max current draw of 3A, so I wired two modules together in parallel to surpass the 4A asked for by the laser.
Plugging in the laser results in a green power light and no status light, but the emission light does not turn on after hitting enable.
We should perhaps buy another DS12 to power the ULN15TK, but I remain confused as to why the other power supply did not work. It is providing the correct voltage, but perhaps wiring two modules in parallel does not increase the current supply as I expect?
The state of the lasers is that both lasers and the amplifier are off. The signs remain on.
Laser seeder and amplifier are back on
The new DS12 arrived in the mail. After using it to power the ThorLabs laser, we found that the 900Hz noise is present, but at a much smaller magnitude compared to the old supply.
