Mastervolt Mass Battery Charger with 230V Input (24V / 100A)

The Mastervolt Mass 24/100 is a 24V, 100A battery charger built for the toughest professional, semi-professional and recreational conditions. With a quoted MTBF of 180,000 hours at full capacity under 24/7 use, it is engineered for round-the-clock reliability. Its lightweight stainless steel and anodised aluminium casing, together with a protective coating on the internal components, resists damp and condensation for a long service life in demanding marine environments. The charger is insensitive to electromagnetic interference from surrounding equipment and supplies stable, ripple free power that stays reliable even with no batteries connected.

Suitable for every battery type, it charges flat batteries and applies an automatic IUoUo 3-step+ characteristic tuned for Gel, AGM, wet and Lithium Ion banks. A temperature sensor is supplied as standard and the unit gives full power at ambient temperatures up to 40 degrees C, feeding a single battery output for banks from 200 to 1000 Ah. The Mass 24/100 is DNV GL certified, holds a Lloyds approval extension, and a GMDSS version is available.

Full MasterBus compatibility lets the charger integrate into 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.
