Advanced Multi-Bank Battery Charging for Marine and Off-Grid Systems
The Victron 12V 20A Multi-Bank Centaur 12/20 (3) Uin 90-265VAC/45-65Hz Battery Charger is engineered to deliver reliable, high-performance power management for demanding marine, automotive, and industrial off-grid applications. Designed to overcome the challenges of fluctuating power supplies and harsh environmental conditions, this battery charger helps maintain your battery banks in optimal condition. Whether you are running a 3 bank marine battery charger setup on a yacht or managing an off-grid system in the Australian outback, this unit provides consistent power without the vulnerabilities of standard grade equipment.
True Multi-Bank Charging Capability
Managing multiple battery systems can be complex, but this unit simplifies the process by offering three fully isolated outputs. Unlike many standard chargers that split their total output, each of the three outputs on this unit can supply the full rated charge current. This makes it an exceptional choice for vessels or vehicles that require simultaneous charging of house, starter, and auxiliary batteries, ensuring all systems are ready when you need them.
Universal Input for Total Reliability
One of the standout features of this charger is its truly universal input voltage range. It operates seamlessly across a 90 to 265V AC input voltage range, and can even accept a 90 to 400V DC supply, making it highly adaptable for AC-DC and DC-DC operations. Crucially, it maintains full output power across the entire specified range. This is incredibly beneficial when dealing with unstable shore power or fluctuating generator outputs, reducing the risk of interrupted charging cycles and dropped voltages.
Intelligent Three-Stage Battery Care
Battery longevity is supported through an automatic, three-stage IUoU charging characteristic. The charger begins with a bulk charge phase until the output reduces to 70% of the rated amps, initiating a four-hour absorption timer. Following this, it seamlessly transitions to a float rate to safely maintain the battery bank over long periods. An internal temperature sensor automatically compensates the charge voltage, protecting your batteries from overcharging in extreme heat. Setup is simple, with a manual DIP switch allowing you to select the precise charge and float voltages for flooded lead-acid, gel, or AGM batteries.
Marine-Grade Durability
Built to withstand the rigours of adverse environments, the internal circuitry is housed within a blue epoxy powder-coated aluminium enclosure. Complete with a drip shield and stainless steel fixings, the exterior actively resists heat, humidity, and salt air. Internally, the circuit boards are treated with an acrylic coating for superior corrosion resistance, while temperature sensors and a controlled cooling fan protect the components from overheating.
Key Features
- Three isolated DC outputs capable of simultaneously supplying the full rated charge current
- Universal 90-265V AC and 90-400V DC input compatibility for worldwide operation
