Built expressly for the added demands of large multi-battery banks, inverter loads, and other substantial electrical demands, Extra-Large Case 97-Series Alternators provide the size, cooling and output across the range of engine RPM required to perform in a league with a small genset.
Extra-large 97-Series alternators ensure unexcelled output under the toughest marine conditions. This robust series of sustained duty alternators features oversized bearings for smoother, quieter rotation, high amperage diodes, bi-directional cooling , and isolated ground.
External regulation required – 97-Series Alternators are designed to be used with Balmar Mulit-Stage Regulators.
