skippy32 Posted April 5, 2018 Posted April 5, 2018 (edited) An MMO mesh anode that I recently purchased states that max anode current density is around 250 - 300 mA/cm^2. I've been trying to figure out how to calculate the max amperage I can send through the anode without damaging it, so far I made this calculation but I'm not sure if it's correct... For a 3" x 5" MMO mesh:3" = 7.62 cm5" = 12.70 cm7.62 cm * 12.70 cm = 96.77400 cm^2If running it at 250 mA/cm^2: 96.77400 cm^2 * 250 mA = 24193.5 mA = 24.1935 A ≈ 24 AIf running it at 300 mA/cm^2: 96.77400 cm^2 * 300 mA = 29032.2 mA = 29.0322 A ≈ 29 A Are the above calculations correct? Also would I need to account for the area displacement from the mesh? I'd assume that if the above calculations are correct, it would correlate to a MMO sheet of that size, and not to a mesh.

Baldor Posted April 8, 2018 Posted April 8, 2018 A link to the datasheet of the anode will be useful. When there is a datasheet or some other tech info about a product we are speaking, a link is always useful. Even a link to where you purchased it. Who knows what overlooked information is hidden in it. For what I have seen in other mesh anode datasheets, mesh size is contemplated when giving you the current density, so you don't need to worry about it. Area calculation is OK, max current calculations are OK too, assuming the current density you give us is correct.
