I have my new Panworld 30PI-Z-D hooked up to the meanwell Nikhsub linked me to a few weeks back. It's working great now, however, it's running at like 25-26volts because the meanwell seems to over-volt a little. This would not be an issue if the pump didn't dump so much heat at these voltages, but it does. The PSU has a pot on it, however when adjusting and measuring with a multimeter, nothing changes...almost as if the pot is not connected or something. Is this the case? Do I need to connect the pot to something? I assumed it just was wired through the pump and just worked...but unless it's broken, it's not doing not.
