Balmar 9648100K8IG 48V 100A High-Output Marine Alternator with K8 Pulley Isolated Ground

The Balmar 96-Series alternator establishes a new standard for emerging 48V battery banks and inverter systems, delivering 4.8 kW of charging power at 100 amps. This isolated ground model features a large-frame design engineered specifically for mid-duty cycle marine applications where high-power 48V charging is essential.

Key Features:

• 100 amp output at 48 volts providing 4.8 kW of charging power
• J-180 4-inch dual foot saddle mounting configuration, typical for Caterpillar, Cummins, Detroit Diesel and John Deere engines
• Isolated ground design for enhanced electrical system protection
• K8 pulley configuration included
• Low RPM cut-in at 2,200 RPM, making more power at lower engine speeds
• High reliability bearings, robust rectifier diodes and improved heat-sinking capabilities
• Sealed heavy-duty radial bearings (front and rear), ventilated cast aluminum construction
• Weight: 19.8 pounds

When paired with the Balmar MC-620 regulator, this alternator combines the advantages of Balmar's legendary multi-stage regulation capability in a 48V charging system. 48V systems offer much more efficient components such as chargers and inverters, manageable cable sizes, and higher output alternators in reasonable package sizes. Lithium batteries can be charged at very high rates, making 48V systems cost-effective for high-power applications.

Important: This alternator must be used exclusively with the MC-620-H regulator with a 12V supply to the regulator. Isolated ground alternator installations require a dedicated cable connecting the alternator ground terminal to system ground.
