It is suited to marine, vehicle, and off-grid installations where multiple battery banks need simultaneous, controlled charging from a single unit. The wide 120-240V AC input range makes it compatible with both UK and international mains supplies.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e40A total output across three independent outputs, allowing simultaneous charging of a main battery bank and two auxiliary banks.\u003c\/li\u003e\n  \u003cli\u003eWide AC input voltage range of 120-240V, suitable for UK, European and North American mains supplies.\u003c\/li\u003e\n  \u003cli\u003eFour-stage adaptive charging algorithm (bulk, absorption, float, storage) adjusts automatically to battery condition.\u003c\/li\u003e\n  \u003cli\u003eCompatible with a wide range of battery chemistries including flooded, gel, and AGM lead-acid batteries.\u003c\/li\u003e\n  \u003cli\u003eTemperature-compensated charging via optional sensor input, protecting batteries in environments with significant temperature variation.\u003c\/li\u003e\n  \u003cli\u003eMicroprocessor-controlled with built-in protection against overcharge, short circuit, reverse polarity and high temperature.\u003c\/li\u003e\n  \u003cli\u003eCompact, wall-mountable enclosure with a weight of 6.4kg, suitable for permanent installation in confined spaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Centaur 12\/40(3) uses a four-stage adaptive charging process. During bulk charge, the full 40A output is applied to bring the battery up to voltage quickly. The absorption stage then holds voltage constant while current tapers, ensuring a full charge without gassing. Float and storage modes maintain the battery at safe resting voltages for extended periods, making the charger suitable for standby and seasonal applications.\u003c\/p\u003e\n\n\u003cp\u003eThe three-output design is a practical feature for installations with separate battery banks, such as a starter battery, a domestic service bank, and a bow thruster or generator start battery on a vessel. Each output is independently managed, so the charger prioritises the bank with the greatest demand without overcharging the others. This removes the need for battery-to-battery chargers or split charge relays in many installations.\u003c\/p\u003e\n\n\u003cp\u003eThe 120-240V AC input is handled automatically, with no manual switching required. This makes the unit straightforward to use in mixed-voltage environments or when equipment moves between regions. All Centaur chargers are built to Victron's standard for continuous-duty operation, meaning they are rated for permanent connection rather than occasional top-up use.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CCH012040000\u003c\/li\u003e\n  \u003cli\u003eOutput voltage: 12V\u003c\/li\u003e\n  \u003cli\u003eOutput current: 40A (three outputs)\u003c\/li\u003e\n  \u003cli\u003eAC input voltage: 120-240V\u003c\/li\u003e\n  \u003cli\u003eWeight: 6.4kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076021490\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMarine vessels with separate starter, domestic and auxiliary battery banks.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes and coaches requiring simultaneous charging of chassis and habitation batteries.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins and outbuildings with mains or generator power available for periodic battery charging.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicles with multiple 12V battery systems.\u003c\/li\u003e\n  \u003cli\u003eStandby power installations where batteries must be maintained at full charge over extended periods.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eVictron Centaur Charger 12\/40(3) 120-240V unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eInstallation should be carried out by a qualified electrician or marine electrical engineer. The unit must be connected to a correctly fused and earthed AC supply in accordance with local wiring regulations. In the UK, mains connections must comply with BS 7671. Battery cabling should be sized appropriately for the 40A output current and kept as short as practicable to minimise voltage drop. If the optional temperature sensor is used, it should be attached directly to the battery casing of the main bank. Do not install in locations exposed to direct water ingress or where ventilation is restricted.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60227834052942,"sku":"CCH012040000","price":368.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_CCH012040000_-_Centaur_Charger_12-40_3_120-240V.webp?v=1785164990","url":"https:\/\/voltaconsolar.com\/products\/victron-centaur-charger-12-40-3-120-240v","provider":"VoltaconSolar","version":"1.0","type":"link"}
