It runs from an AC input between 120 and 240V, so it works on UK, EU and North American supplies without switching.\u003c\/p\u003e\u003ch2\u003eMarine battery charger with three outputs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e20A main output plus two 4A auxiliary outputs, so three battery banks can charge at the same time.\u003c\/li\u003e\n\u003cli\u003eAutomatic four-stage charging: bulk, absorption, float and storage, suited to gel, AGM and flooded lead-acid batteries.\u003c\/li\u003e\n\u003cli\u003eAdaptive absorption time based on how long the bulk stage took, rather than a fixed period.\u003c\/li\u003e\n\u003cli\u003eStorage mode drops the float voltage after 24 hours to reduce corrosion and water loss during long idle periods.\u003c\/li\u003e\n\u003cli\u003eTemperature-compensated charging available with an optional sensor.\u003c\/li\u003e\n\u003cli\u003eSealed, vibration-resistant build with protection against reverse polarity, short circuit, overheating and high AC voltage.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTransformer-based design\u003c\/h2\u003e\u003cp\u003eCentaur chargers use a transformer rather than high-frequency switching, which makes them tolerant of voltage spikes and a noisy AC supply. That suits marinas, generator-fed sites and other locations where mains quality varies.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eFits vessels with separate main and auxiliary battery banks, motorhomes and coaches with leisure and starter batteries on one charger, and standby systems with multiple lead-acid banks. Also works well on narrowboats and static caravans left connected for long periods, thanks to the storage mode.\u003c\/p\u003e\u003ch2\u003eSpecification highlights\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOutput voltage: 12V\u003c\/li\u003e\n\u003cli\u003eMain output current: 20A\u003c\/li\u003e\n\u003cli\u003eAuxiliary output current: 4A + 4A\u003c\/li\u003e\n\u003cli\u003eAC input voltage: 120 to 240V AC\u003c\/li\u003e\n\u003cli\u003eWeight: 4.3 kg\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFit by a qualified electrician or competent marine or vehicle electrician, with the AC supply correctly fused and DC cabling rated for the run length and battery configuration.
