ICCP power-supply rating from required hull-protection current, voltage, and design margin - the unit spec for new-build / retrofit.
Formula
$$ P_{DC} = I_{design} \cdot V, \quad P_{AC} = P_{DC} / \eta_{rectifier} $$Symbol legend
| Symbol | Meaning | Unit | Source |
|---|---|---|---|
| $I_{design}$ | Design protection current | A | corrosion study |
| $V$ | Anode circuit voltage | V | anode characteristic |
| $\eta$ | Rectifier efficiency | - | 85 % typical |
