Delivering a substantial \u003cstrong\u003e100A charge current\u003c\/strong\u003e for 24V battery banks, this unit is purpose-built for commercial marine vessels, mobile service vehicles, and critical off-grid infrastructure where electrical reliability is paramount.\u003c\/p\u003e\u003cp\u003eUnlike standard consumer chargers that often struggle in high-ambient temperatures or corrosive conditions, the Mass series is designed to deliver full rated output in temperatures up to 40°C. It is compatible with every battery chemistry, including Lithium-ion, Gel, AGM, and flooded lead-acid, and features specialized circuitry capable of safely recovering completely flat batteries.\u003c\/p\u003e\u003ch3\u003eEngineered for Harsh Environments\u003c\/h3\u003e\u003cp\u003eEquipment installed in engine rooms, coastal facilities, and mobile plant compartments faces constant exposure to moisture, vibration, and heat. The Mass 24\/100 mitigates the risk of premature failure through a lightweight yet robust chassis constructed from stainless steel and anodised aluminium. Internally, vital electronic components receive a protective conformal coating to prevent short circuits and corrosion caused by dampness or condensation.\u003c\/p\u003e\u003cp\u003eInstallation is straightforward and secure, utilizing heavy-duty side-mount flanges and protected bottom cable glands for clean wiring entry. An integrated front-facing LED status display and manual rocker switch allow for immediate local monitoring and control.\u003c\/p\u003e\u003ch3\u003eClean Power and Intelligent System Protection\u003c\/h3\u003e\u003cp\u003eBeyond simple battery charging, the Mastervolt Mass 24\/100 functions as a highly stable, ripple-free 24V DC power supply even without a battery connected. This allows system integrators and technicians to safely power sensitive DC loads, navigation equipment, and communication arrays directly from the mains without introducing electrical noise or electromagnetic interference.\u003c\/p\u003e\u003cp\u003eTo protect upstream AC infrastructure, the integrated Current Control function automatically reduces the charging current if the incoming AC voltage drops, effectively preventing shore power or generator fuse breakdown. For large-scale energy storage systems exceeding 1000Ah, multiple Mass chargers can be switched in parallel to increase total amperage capacity and provide critical system redundancy.\u003c\/p\u003e\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Output in High Heat:\u003c\/strong\u003e Delivers continuous 100A charging performance in ambient temperatures up to 40°C without thermal derating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Battery Compatibility:\u003c\/strong\u003e Precisely charges Gel, AGM, flooded, and Lithium-ion batteries, including deeply discharged units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandalone Power Supply Mode:\u003c\/strong\u003e Provides a stable, ripple-free 24V DC output for running sensitive electronics without a battery inline.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine and Industrial Compliance:\u003c\/strong\u003e Certified to DNV GL, RRR, and RMRS standards, with connections adhering to CE, ABYC A-31, and IEC 60945 guidelines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive AC Fuse Protection:\u003c\/strong\u003e Built-in Current Control automatically scales back power draw during AC voltage drops to prevent nuisance tripping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental Resilience:\u003c\/strong\u003e Anodised aluminium housing and coated internal electronics resist salt mist, condensation, and electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Thermal Management:\u003c\/strong\u003e Includes a standard temperature sensor to optimize charge voltages based on battery temperature, extending cell lifespan.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eUpgrade Your 24V Power Infrastructure\u003c\/h3\u003e\u003cp\u003eEquip your vessel, commercial fleet, or off-grid installation with a charging solution built for continuous duty.
