Victron Energy Centaur Charger 12/40 (3) – CCH012040000

The Centaur charger 12/40 features auto-ranging input covering 90-265VAC 50/60Hz input meaning they can be used anywhere in the world.

Crucially, and unlike many other products that state universal input, the Centaur charger range will maintain full output power within the entire specified range. Other features include fully automatic three stage charge characteristic that ensures batteries are fully charged every time and three isolated charge outputs for multi battery configurations to suit the majority of typical installations.

Features of the Centaur Charger 12/40

Quality without compromise

Aluminium epoxy powder coated cases with drip shield and stainless steel fixings withstand the rigors of an adverse environment: heat, humidity and salt air. Circuit boards are protected with an acrylic coating for maximum corrosion resistance. Temperature sensors ensure that power components will always operate within specified limits, if needed by automatic reduction of output current under extreme environmental conditions.

Universal 90-265V AC input voltage range and also suitable for DC supply (AC-DC and DC-DC operation)

All models will operate without any adjustment needed over a 90 to 265 Volt input voltage range, whether 50 Hz or 60 Hz.

The chargers also accept a 90-400 V DC supply.

Three outputs that each can supply the full output current

The Centaur charger has three isolated outputs to simultaneously charge 3 battery banks. Each output is capable to supply the full rated current.

Three-stage charging, with temperature compensation

The Centaur 12/40 Charger charges at bulk rate until the output has reduced to 70% of the rated Amps, at which a 4 hour timer begins. After the timed period the charger switches to float rate. An internal temperature sensor is used to compensate the charge voltage with “ 2 mV/ºC (“ 1 mV/ºF) per cell. A DIP switch is available to select the optimum charge/float voltages for Flooded Lead-acid, Gel or AGM batteries.
