Description

Mastervolt Alpha Pro III 45513000 is an advanced 3-step charge regulator for standard and high performance alternators. Applications range from improving the performance of a standard alternator in a boat, to generator replacement, when combined with a high performance alternator.

The propulsion engine of your boat may be used to quickly charge your service batteries, either while cruising or taking a break. The Mastervolt Alpha Pro III ensures safe and fast charging, protecting both the batteries and the engine. From 10 years of experience, the Alpha Pro III brings higher power and improved ease of use, along with a modern look.

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

Pull the max out of your alternator
The alternator that comes with the engine is not optimally suited for charging service batteries; instead it is 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 (not allowed on Euro 5/6 engines) optimizes the charging process, protecting against over-heating, over-charging and extends the lifetime of your batteries.

Super charge your system
Mastervolt recommends to combine the Alpha Pro III with a high performance alternator such as the reliable Mastervolt Alpha series for superfast charging at low RPM. 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.

Alpha Pro III: Fast charging, anytime, anywhere.
