Hello all,
I am new to arduino, and am still in the research stage of my project. I plan to use an arduino mega. My goal is to replace my home pool control board that controls 2 pool pumps and the saltwater chlorine generator. I think I have been able to research solutions for most of what I need (including controlling pumps and monitoring water levels) except for the matter of supplying power to the salt cells. Currently the salt cells are connected to the control panel (Autopilot DIG-220, malfunctioning at the moment).
There are different power levels for the cells, depending on how much chlorine needs to be generated, but the max level supplied is 26VDC at 8 amps. My supply could be either 120VAC or 240VAC, as both are present at the control board.
My question is what are the options for obtaining that voltage and current (which seems like a pretty strong current)? In my research I have not seen any power supplies that supply that voltage and amperage, at least not affordable. I have researched a little about bridge rectifiers and using transformer + diodes + capacitor + regulator. Is this the best method? Are there other methods I have not come across?
Would controlling such a current with an arduino be feasible? Would I be able to adjust the voltage and current depending on chlorine levels?
Thank you all for your help.
