I saw a few years back you discussed using the intellichlor power center's 35-40VDC to power your peristaltic pump.
It still seams to me that would be a simple way to grab 24VDC for the acid pump, using a cheap buck converter. Also it would have the added protection of only being a power source when the filter pump is running.
Actually, I was using the IntelliChlor's transformer to power a regular ole IntellipH, which is the standard practice for those using IntellipH..
However, back in the beginning of 2021, I discontinued my use of the IntellipH system (darn, that reminds me that I still need to remove that ipH controller from the wall adjacent to my equipment pad
Anyway, I switched over to letting njspC/REM control acid dosing based on pH readings obtained from an Atlas Industrial pH probe.
I retained the use of the original Pentair chemical tank and peristaltic pump however and just ditched the ipH controller.
Now I am powering the pump with a MEAN WELL EDR-120-5. 24V, 5-amp, 120W PSU
via the following relay card.

In addition, @rstrouse
really helped me out by suggesting the use of a Snubber Circuit Module and showing me how to connect it all up.
If you're interested, I provided further details of all of this in the first post of this thread.
One thing I should note. I can't tell you how effective and trouble free (no pun
), that this entire system has been for me over the last 18 months. From the hardware side of it as well as the software applications that really are the heart of it all.
Other than either replenishing acid in the chemical tank or making fine tuned adjustments to my IntelliChlor output level as indicated on either my njspC dashPanel or from looking at my Grafana dashboard, my pool maintenance is about as negligible as I can get it.
Hope that helps a bit.
Have a happy Independence day...
