Product details

The Mastervolt Mass 24/50-2 (DNV GL) battery charger is engineered for demanding conditions in professional, semi-professional, and recreational environments. This robust charger delivers consistent full output power continuously, even under harsh operating conditions. With a mean time between failures of 180,000 hours at full power during 24/7 operation, it provides a reliable power supply where dependability is essential. The unit features a lightweight, rust-proof anodized aluminum housing with internal component coatings that protect against moisture and condensation, ensuring a long service life. It operates effectively in temperatures up to 40 °C while maintaining full power output. This charger is compatible with all battery types, including completely discharged batteries, and includes a standard temperature sensor. It supports battery capacities from 80 to 1000 Ah or more and provides stable, ripple-free power even without a battery connected. The current control function prevents fuse tripping during voltage drops, and parallel connection is possible for multiple chargers. Certified by DNV GL, RRR, and RMRS, the charger meets CE, ABYC A-31, and IEC60945 standards. GMDSS compatible versions are available for compliance with SOLAS regulations, enabling monitoring of various alarm functions. The MasterBus compatibility allows simple installation with a single-cable connection to MasterBus networks for centralized, local, or remote monitoring, configuration, and operation. Designed to withstand severe vibrations and shock movements, the charger uses high-quality materials manufactured to the highest specifications. The mounting system provides professional installation results with extra solidity. Available accessories include remote control panels compatible with all Mass battery chargers and separate front displays with GMDSS remote control panels for specific models.
