Description

The Mastervolt Mass 24/25-2 is a 24V, 25A battery charger designed for the toughest professional, semi-professional and recreational conditions. Its lightweight stainless steel and anodised aluminium casing, combined with a protective coating on the internal components, guards against damp and condensation to ensure a long service life in demanding marine settings. The charger is insensitive to electromagnetic interference from nearby equipment and provides a stable, ripple free supply that remains reliable even when no batteries are connected.

Suitable for every battery type, it charges flat batteries and applies an automatic IUoUo 3-step+ characteristic optimised for Gel, AGM, wet and Lithium Ion banks. A temperature sensor is included as standard and the unit delivers full power at ambient temperatures up to 40 degrees C. A second 3A output keeps a starter or auxiliary battery charged. The Mass 24/25-2 is also DNV GL certified and available in a GMDSS version.

Full MasterBus compatibility lets the charger join a wider Mastervolt network over a single cable for central, local or remote monitoring and control. Multiple units can be switched in parallel, and the Current Control function prevents fuses from blowing when the input voltage falls.
