NEW MASTERVOLT ALPHA PRO III REGULATOR TRANSFORMS ANY ALTERNATOR INTO AN A BATTERY CHARGER

NEW MASTERVOLT ALPHA PRO III REGULATOR TRANSFORMS ANY ALTERNATOR INTO AN A BATTERY CHARGER

Not all boat engine alternators have been optimized for efficient battery charging, but the new Alpha Pro III regulator will change all that. Compatible with any alternator or battery type, it will greatly boost your boat’s charging ability.

Mastervolt, the Dutch based leader in off-grid electrical systems, is proud to announce the arrival of the Alpha Pro III, an advanced, temperature-controlled regulator that will greatly enhance the efficiency of any type of marine alternator. The new regulator not only provides a three-step charging process, the most efficient and safest regime available, it also monitors the engine load to help reduce engine noise, and wear and tear on the alternator’s components.

The Alpha Pro III is an intelligent regulator, and if required can communicate with the rest of the electrical system via the MasterBus data cable. The electronics provides a smart ‘keep alive’ feature ensures reliable tachometer readings. Using MasterBus, the regulator communicates RPM, alternator status and charge status to the rest of the electrical system, all of which can be automated or controlled via an EasyView 5 touch screen.

Maximise your alternator

Many boats are fitted with a standard alternator, a low-cost unit that will only charge the batteries relatively slowly. They can also easily overheat, which further impairs charging efficiency. By replacing the standard regulator with an Alpha Pro III, a boat owner will access a much faster charge cycle along with protection for the batteries against overheating and overcharging. Combined with the three-step charging process, these safeguards will greatly extend the lifespan of the battery bank.

Even greater efficiency

To really pull in the amps, even at low RPM, Mastervolt suggests combining the Alpha Pro III with a high-performance regulator such as the proven Alpha series, some of which can output up to 400 A. The Alpha Pro III is the only three-step regulator on the market capable of handling these high output loads.

Designed for easy installation, the Alpha Pro III is the distillation of 20 years of Mastervolt’s experience in providing fast, reliable charging that protects your batteries whilst maximizing their efficiency and lifespan.
