Mode Description Bulk Charge Delivers maximum current until the battery voltage reaches a pre-set level. Absorption Charge Maintains voltage while gradually reducing current, ensuring full charge without gassing. A 4-hour timer is initiated when output current drops to 70% of rated Amps. Float Charge Maintains a lower voltage to compensate for self-discharge, keeping the battery fully charged indefinitely. An internal temperature sensor provides automatic compensation of the charge voltage at –2 mV/ºC per cell, optimising charging performance across varying temperatures. DIP switches allow users to select specific charge/float voltages tailored for Flooded Lead-acid, Gel, or AGM battery types. With three isolated outputs, this charger can simultaneously charge up to three separate battery banks, each receiving the full rated current, making it highly versatile for complex power systems. Typical Applications Application Description Marine Vessels Ideal for yachts, workboats, and recreational craft, charging engine start, service, and auxiliary battery banks. RV & Campervans Ensures leisure batteries are fully charged when connected to shore power or a generator. Off-Grid Systems Provides reliable AC or DC charging for battery banks in remote cabins or solar installations. Industrial & Backup Power Suitable for maintaining batteries in backup power systems, telecommunications, and industrial equipment. Built-In Protection Functions The Victron Centaur Charger 12V/40A is equipped with integrated protection features to safeguard both the charger and connected batteries. Temperature sensors continuously monitor power components, automatically reducing output current under extreme environmental conditions to ensure operation within specified limits. The robust design, including epoxy powder-coated aluminium cases and acrylic-coated circuit boards, provides excellent resistance against heat, humidity, salt air, and general corrosion.
