Its robust design is certified for shock and vibration resistance, making it the premier choice for commercial shipping, naval vessels, and any application where system failure is not an option.

This advanced battery charger is more than just a power source; it´s the heart of a sophisticated energy system. With its integrated MasterBus, CZone, and NMEA 2000 compatibility, it allows for seamless communication, monitoring, and control of your entire onboard power network from a single display. The Mass 48/25-2 can function as a standalone power supply even without batteries connected, providing stable and clean DC power for critical equipment. Its intelligent 3-step+ charging algorithm ensures the fastest and safest charge for all battery chemistries, including Gel, AGM, wet-cell, and modern Lithium-Ion, maximizing their performance and lifespan.

Key Benefits:

* Built for the Toughest Conditions: Designed for extreme environments with a lightweight, corrosion-resistant anodized aluminum casing and internal components coated to prevent damage from moisture or condensation. Certified by DNV, Lloyd´s, and other maritime authorities.
* Intelligent and Fast Charging: The proven 3-step+ charging process automatically adjusts for optimal bulk, absorption, and float phases. The included temperature sensor provides real-time compensation, preventing over or undercharging and significantly extending battery life.
* Complete System Integration: Full MasterBus compatibility enables you to build a fully integrated power system. Monitor charge status, adjust settings, and receive alarms on a central MasterView panel or connect to other CZone and NMEA 2000 networks.
* Versatile Power Solution: Capable of charging two separate battery banks and can also be used as a direct DC power supply. The current control function allows you to manage AC input power, preventing tripped breakers when on limited shore power.
* Global Compatibility: With automatic voltage sensing, the charger accepts a wide input range of 90-265V AC at 50/60Hz, allowing for reliable operation anywhere in the world.
