It delivers a total charging current of 50 A at 28.5 V, with two separate battery outputs, including a secondary 3 A output dedicated to small battery banks such as starter batteries.\n\u003c\/p\u003e\n\u003ch3\u003eDesign and performance\u003c\/h3\u003e\n\u003cp\u003e\n    This charger operates on a nominal input voltage of 230 V (range 180–265 V) at 50\/60 Hz. It uses an automatic 3-step+ IUoUo charging characteristic suitable for Gel, AGM, flooded, and Lithium Ion batteries, capable of charging even fully discharged batteries. Charging voltages are 28.5 V in Bulk and Absorption, with a 4-hour absorption time. Float voltages are 26.5 V for flooded batteries and 27.6 V for Gel\/AGM batteries. It is recommended for battery banks of 100 to 500 Ah but can adapt to capacities from 80 to 1000 Ah and beyond. The power supply mode allows it to provide stable, ripple-free power even without batteries, which is essential for sensitive equipment.\n\u003c\/p\u003e\n\u003ch3\u003eReliability and system integration\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eMass 24\/50-2 230V\u003c\/strong\u003e features a lightweight stainless steel and anodized aluminum construction, with internally coated components for protection against moisture, condensation, and corrosion. It is designed to withstand vibration and shock, ensuring a long service life. It operates at full power up to 40°C or 45°C. A temperature sensor is included to optimize charging based on battery temperature. The current control function reduces charger power to prevent fuse blowouts in case of voltage drop. Multiple chargers can be connected in parallel to increase charging capacity. MasterBus compatibility enables monitoring, configuration, and centralized control via a single cable. The charger is also compliant with GMDSS (Global Maritime Distress and Safety System) and SOLAS regulations, featuring galvanic isolation, enabling real-time monitoring of essential alarm functions for marine safety. Its MTBF (Mean Time Between Failures) is 180,000 hours at full load, or 280,000 hours according to some sources. It is certified DNV GL, CE, ABYC A-31, and IEC60945, ensuring compliance with international safety and quality standards for marine and industrial applications.\u003c\/p\u003e","brand":"Mastervolt","offers":[{"title":"Default Title","offer_id":56136965718356,"sku":"40020506","price":1203.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/family-42020506-40020506-1.jpg?v=1781647448","url":"https:\/\/skysat.fr\/en-gb\/products\/mastervolt-mass-24-50-2-230v-dnv-gl-battery-charger","provider":"Skysat","version":"1.0","type":"link"}
