Purpose and operating parameters

The presented alternator is designed to work with Diesel engines, where the demand for electrical energy is higher due to advanced electronics and auxiliary systems. A current output of 200 A at 14 V allows for stable operation of consumers such as engine control units, comfort systems, lighting, safety systems, or additional onboard equipment.

An alternator configured in this way will perform well in vehicles used both in city traffic and on longer routes, where resistance to variable electrical loads and maintaining the proper battery charge level is essential.

Construction and function in the charging system

The alternator from this series belongs to the group of components responsible for continuous generation of electrical energy while the engine is running. In combination with the voltage regulator and the battery, it forms a complete charging system that:

• powers current electrical consumers in the vehicle,
• maintains the proper voltage level in the system,
• is responsible for recharging the battery under various load conditions.

Thanks to appropriately selected parameters, the alternator reduces the risk of voltage drops, flickering lights, or starting problems after a long period of inactivity, which is especially important in vehicles with extensive electronics and additional comfort systems.

Application in Mercedes vehicles with a diesel engine

The alternator is intended for installation in selected Mercedes models from the W207, W212, and W906 series equipped with a diesel engine. The design was developed with the requirements of diesel units in mind, where it is essential to combine adequate current output with mechanical durability and resistance to operating conditions in the engine compartment.

Proper matching of the alternator to a specific vehicle version allows for maintaining the factory parameters of the charging system, which translates into predictable behavior of the electrical system and reduces the risk of improper interaction with control electronics.

Condition, selection, and benefits of use

The offered alternator is a used component, which is a cost-effective service solution for users looking for parts with factory operating characteristics while maintaining reasonable repair costs. Choosing a component from this group allows for compliance with the vehicle manufacturer's requirements and reduces the risk of problems resulting from improperly selected replacements.

Before purchasing, it is recommended to compare the alternator parameters with the vehicle documentation and the existing charging system to ensure proper fitment in terms of engine type, electrical system, and mounting method.
