Mastervolt Alpha Pro III Advanced 3-Step Charge Regulator with Extended 13′ Harness
The Mastervolt Alpha Pro III Advanced 3-Step Charge Regulator is a universal regulator for N-type alternators. It transforms every alternator into a fully temp controlled 3-step charger, no with a longer harness with alternator temperature sensor included.
The propulsion engine of your boat or vehicles may be used to quickly charge your service batteries, either while cruising or taking a break. The advanced and powerful Alpha Pro III ensures fast and safe charging, protecting both the engine and the batteries. Building on 10 years of experience, the Mastervolt Alpha Pro III Advanced 3-Step Charge Regulator features a modernized look, higher power and improved ease of use.
The Mastervolt Alpha Pro III Advanced 3-Step Charge Regulator measures the temperature and the voltage of your batteries to prevent overcharging, keeping them in perfect condition. It also monitors the engine load, thus 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.
Pull the max out of your alternator
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)
Super charge your system
For super fast charging at low RPM, Mastervolt recommends to combine the Mastervolt Alpha Pro III Advanced 3-Step Charge Regulator (45513040) 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 400 A!

Benefits of a Mastervolt Charge Regulator
The Alpha Pro charge regulator maximizes the output of Mastervolt Alpha alternators or any other alternator by regulating the alternator in a way that the batteries receive the optimum charge. The proven 3-step+ charge method used by all Mastervolt battery chargers guarantees fast and safe charging of your batteries.
The Alpha Pro helps to cut emissions by requiring less run time because it maximizes the power from any alternator. A battery can be charged quickly even at very low RPM, especially when connected to an Alpha series alternator. By connecting the Alpha Alternator to a Battery Mate or battery isolator, several battery banks can be charged simultaneously.
Does your tachometer sometimes indicate zero while the engine is running? The ‘keep alive’ function of the Alpha Pro gets rid of this problem forever.
