Mastervolt Alpha Pro III 45513000 - Optimized Power Management System

The Mastervolt Alpha Pro III is an advanced 3-step charge regulator designed for standard and high-performance alternators. It is perfect for boats or vehicles where the propulsion engine can be used to charge service batteries while cruising or taking a break. The Alpha Pro III ensures fast and safe charging, protecting both the engine and the batteries. It features a modernized look, higher power, and improved ease of use, building on 10 years of experience.

Features:

• Transforms every alternator into a full temperature-controlled 3-step charger.
• Reduces run time, saves fuel, reduces noise and emissions.
• Protects from overcharging and extends battery life.
• Balances engine load, reducing RPM variations.
• Compatible with standard and high-performance alternators, including 200A and 400A models.
• Integrated 'keep alive' feature for reliable tachometer readings.
• Suitable for every battery type, including Lithium Ion.
• Suitable for 12V and 24V system voltages.
• Masterbus compatible: simplifies wiring, saves space and weight, and creates optimal cooperation between Mastervolt products.

The Alpha Pro III measures the temperature and voltage of your batteries to prevent overcharging, keeping them in perfect condition. It also monitors the engine load, reducing sound variations, wear and tear. The smart 'keep alive' feature solves a common problem causing unreliable tachometer readings. Via MasterBus, it communicates RPM, alternator status and charge status to create intelligent power systems.

The alternator that comes with the engine is not optimally suited for charging service batteries. Designed for low cost and short charge cycles, it charges at a slow pace and is easily overheated. Replacing the standard regulator with the Alpha Pro III optimizes this charging process, protects against overheating and overcharging and extends the lifetime of your batteries. (Not allowed on Euro 5/6 engines)

For super-fast charging at low RPM, Mastervolt recommends combining the Alpha Pro III with a high-performance alternator such as the reputable Alpha series. With 20 amps of field current capability, the Alpha Pro is the only 3-step regulator in the market capable of controlling alternators with outputs up to 400A!

Applications:

Applications range from improving the performance of a standard alternator in a vehicle or boat to generator replacement when combined with a high-performance alternator.
