This alternator comes equipped with a single-groove pulley featuring an outside diameter (OD) of 82mm—a design specifically optimized for a particular power transmission ratio. Its rotational direction is configured for clockwise (CW) operation; this directional design is typically engineered to ensure optimal mechanical compatibility with specific passenger car or light commercial vehicle engines, thereby guaranteeing OE-level standards for belt tension and transmission smoothness.
Electrical Specifications and Professional Compatibility: This product delivers an output of 50A at 12V, making it ideally suited for light-duty diesel or gasoline-powered systems with moderate electrical loads. Utilizing an IR/EF (Internal Regulator/External Fan) architecture, it integrates voltage regulation functionality within a compact housing; furthermore, it employs an external fan to facilitate forced-convection cooling, thereby ensuring the reliability of the rectifier diodes even within the high-temperature environment of an engine compartment.
