High-output marine alternator delivering powerful charging for large battery systems
This high-output marine alternator is engineered to deliver reliable charging performance for demanding onboard electrical systems. Designed for marine, RV, and commercial applications, it provides up to 275 A of charging capacity to rapidly replenish large battery banks while maintaining stable performance across varying engine speeds. The large-frame design incorporates external voltage regulation capability, an isolated ground configuration, and efficient thermal management to support sustained high-current output. Featuring a side battery post connection, DF315 saddle mounting configuration, and a 49 mm K6 serpentine pulley, it is optimised for installations requiring robust power generation and compatibility with advanced battery technologies including lithium systems.
Key Features
- High 275 A Charging Output: Provides powerful charging capacity to rapidly replenish large battery banks and support high electrical loads on marine vessels and mobile power systems.
- Externally Regulated Design: Supports use with an external voltage regulator, enabling precise charging control and optimisation for various battery chemistries including lithium.
- DF315 Saddle Mount Configuration: Designed with a 3.15-inch DF315 saddle mount for compatibility with many marine engine installations.
- Side Battery Post Connection: M8 threaded side-mounted battery post provides a secure electrical connection and flexible installation routing.
- 49 mm K6 Serpentine Pulley: Six-groove serpentine pulley ensures reliable belt engagement and efficient power transfer for high-output charging.
- Large-Frame High-Efficiency Construction: Utilises a heavy-duty large frame with high-density stator design to maximise energy production and durability.
- Optimised Thermal Management: Advanced cooling design helps maintain lower operating temperatures for consistent high-current output.
- High Idle Charging Capability: Engineered to produce strong charging performance even at lower engine speeds, ensuring batteries continue charging during idle operation.
Reliable high-capacity charging performance helps support modern onboard electrical systems while reducing the need for additional generator power.
