We have an application where one less power supply would be helpful. In our case, could we use the Rio DC outputs to constantly supply (24/7) 12VDC to one of these, and then add another separate one ~6 times/day for 3 minutes on a timer set in Node-RED? (meaning two separate 12VDC units running independently)
My hope (perhaps misplaced) was that the Rio’s output would handle this. But in hindsight, I think we could take a regular 12V power supply and split it into 3 outputs so that one goes to the Rio (which requires 10–32 V DC) and one goes to each air pump.
