About this product
The ARCO Marine Zeus A220 is a heavy-duty, high-output alternator engineered for demanding marine and diesel engine applications. It is designed to rapidly charge large battery banks and support high electrical loads, often reducing the need for an auxiliary generator by producing additional power directly from the engine.
This unit features dual internal cooling fans to maintain lower operating temperatures for sustained performance and extended service life. Note: This alternator requires an external regulator (sold separately) for operation.
