I built a uds along with a pid controller. I've done thorough research, or so I thought, about wiring everything up. I got everything wired and then plugged it in to test it out. The pid turns on and sends the signal to the ssr, but the fan doesn't turn on. I tested the fan on its own power supply and it works fine. I've attached some pictures of my fan and the power supply I'm using for it, should I be using something different??

Do you have two transformers going? The wall power supply is transforming inputting AC and outputting DC, for your fan. Is the SSR doing any transformation? It looks like its turning DC back into AC... and the fan is DC.
I would get a DC-DC solid state relay, see if that works.
