48 Volt, 100 Amp Alternator (4.8kW), K8 Pulley J-180 4" Dual Foot Mounting - Standard/Case Ground

The Balmar 96-48-100-K8 is a 100-amp, 48-volt marine alternator that delivers 4.8 kW of charging power, part of the 96-Series that Balmar built for the growing number of 48-volt battery banks and inverter systems. A 48-volt architecture allows more efficient chargers and inverters, smaller cable sizes and high alternator output in a sensible package, and it suits lithium banks that accept very high charge rates. With a turn-on threshold near 2,250 RPM, the 96-Series begins making power early in the rev range, limiting the need for complex pulley schemes or over-throttling the engine at idle. The 96-48-100-K8 has a large-case, positive field excitation design with dual internal cooling fans, sealed heavy-duty bearings and a ventilated cast-aluminium case with a clear-anodised finish. It mounts on a 4 inch dual-foot saddle in the J-180 style and drives a K8 serpentine pulley, handling up to 11 horsepower of power take-off. This version uses a case-ground termination. It operates exclusively with the Balmar MC-620 multi-stage regulator, which itself requires a 12-volt supply and cannot be powered from the 48-volt source; the alternator will not run without it. For lithium charging the MC-620 disables output at or below 0 C, using the MC-TS-A and MC-TS-B temperature sensors.
