Mass 24/25-2 DNV certified
Install Mastervolt Mass battery chargers and rest assured that your batteries are always quickly and completely charged, whether you are at home, on the road or at sea with low shore power or limited supply.
Designed for larger, more professional systems with larger battery capacities, the basic technology consists of high-frequency electronics with no heavy or noisy transformers. Thanks to the intelligent cooling concept, the Mass battery charger offers maximum performance, even in the hottest engine room. Besides the fast and complete charging of two batteries (recommended) this charger also functions as a supply unit when the input is low, automatically making up the full capacity in the 24 V circuit. Mastervolt’s 3-step+ charging method guarantees optimum efficiency, meaning your batteries will perform better and last much longer. Its direct current outlet is so clean that the battery charger itself can be used as direct power source, even without a battery.
The high-frequency switch mode technology, in which advanced microprocessors combine a myriad of functions, causes an extremely accurate charge characteristic. Furthermore, this Mass battery charger has an unique memory function which prevents the charger starting a new 3-step+ charge cycle if the supply voltage is interrupted. The model is equipped with an LED status indicator displaying the stage of the 3-step charge cycle while several remote panels are available as option for even more convenience. All in all it gives you the power to be independent!
