Zeus A4000-24V Low Turn On (LTO) Alternator - Housing: 4" J180 Saddle

Coolest operating temperatures for increased performance, durability, and service life. Runs 8 - 20% cooler than incumbent alternators.Engineered for high energy production.Suitable for marine, RV, military, and commercial applications.High-density, ultra-efficient stator winding produces maximum energy output.Rapidly charges large battery banks.Optimized for performance at idle speeds.Reduces the need for a generator by creating additional power with your engine.Dual fans provide more efficient cooling, which enables higher sustained output and increases the durability and lifespan of the unit.SAE J1171 Certified.Turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier.This alternator continuously generates over 1.4kW (51 amps) at just under 1,500 RPM and almost 2.4kW (87 amps) at 2,000 alternator RPM.Maximum output: 3,960 watts (144 amps).Sustained cruising output: 3,575 watts (130 amps). Sustained idle output: 2,970 watts (108 amps).Pulley: 49mm K6 (6 groove).24 volt.Housing: 4" J180 Saddle.Applications: Replaces most Volvo Penta alternators using a 4" J180 saddle style mount. Also used on many larger industrial-based engines.External only.Ground type: Isolated ground.
