Mex, what is the lowest voltage a MegaWatt will goto with a 500 OHM potentiometer?
I get that these will mostly be in thee 14.5v range where the losing some bottom end does will not matter, but I'd personally hate to not be able to go as low as the low 13's.
When I replaced the 1K ohm pot( measured at 973 ohms) with a 10 turn pot(1024 ohms) On my Meanwell, my minimum voltage dropped from 13.23 to 13.12v. More resistance = lower voltage, Zero resistance = max voltage.
I think I would lose the lower end of My MeanWell voltage range with a 500 ohm pot, making it useless floating flooded batteries, perhaps even too high for my AGM.
I feel the 10 turns pot 1K ohm is precise enough I can dial in voltage to 0.01v easily enough, and The Meanwell rsp-500-15 has a 6+ volt range of adjustment with a 1K ohm pot.
What is the max voltage of the Megawatt? Trojan now specs 16.2v equalization voltage.
Perhaps those wanting more than 15.5v for flooded battery Equalization, might want a Meanwell rsp-500-15. 40 amps, power factor corrected, and a 13.12 to 19.23 voltage range, but also twice the price of the Megawatt.
