BALMAR 97-SERIES ALTERNATOR DATA SHEET REVISED 08/24/10 Balmar’s 97-Series, extra-large case alternators deliver the size and charging output required to support battery banks of up to 750 amp hours at 12 volts or 500 amp hours at 24 volts. These 12-volt and 24-volt alternators are engineered for use with external multistage voltage regulation, making it possible to tailor charging voltage to maximize safety and efficiency when replenishing a wide variety of battery types. A robust J180 saddle-style dual foot mounting configuration is ideal as a replacement for standard J180 mount alternators or for use as a second alternator on custom J180 saddle mount brackets. Isolated grounding termination provides sure continuity to system ground. High amperage diodes and extra-large sealed bearings ensure dependability and long alternator life. Included in the 95-Series alternator family are: 150-amp/12-volt; 165-amp/12-volt; 210-amp/12-volt; and 140-amp/24-volt models. All models meet U.S. Coast Guard Title 33 standards for ignition protection.
