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??
