Victron Centaur Charger 12/20 (3) 12v 20a battery charger 3 outputs

The Centaur 12/20 (3) from victron Energy (mpn cch012020000) is a high quality battery charger for 12v batteries with 3 charging outputs and 20a maximum charging current, which can be distributed as desired among the 3 outputs. Thanks to its wide input voltage range of 90-265 v ac, the Centaur 12/20 (3) can be used almost anywhere in the world without any special settings. The IUoU charging characteristic with three-stage characteristic ensures gentle charging of your battery(ies). The Centaur is suitable for charging gel, agm and lead acid batteries, where the battery type can be quickly selected via a DIP switch on the housing of the device.

The Centaur battery charger is fully high frequency regulated. The power input is electronically controlled by the power factor in the first power stage. The next stage provides galvanic isolation and ensures perfect DC voltage at the outputs. The electronic components are protected against moisture and dirt by a special coating to ensure the longevity of the device. Three high power batteries can be charged simultaneously with this charger

Centaur 12/20 (3): quality without compromise

An aluminum housing with epoxy powder coating, drip protection against condensation water and stainless steel mounting parts allow the Centaur 12/20 to withstand the toughest demands such as heat, humidity and salty atmospheres. The circuit boards are safely protected against corrosion by an acrylic coating. Temperature sensors ensure that all power components operate within specified limits and, if necessary, the output current is automatically reduced in extreme conditions.

Three-stage charging characteristic with temperature compensation

Centaur initially charges at constant current (bulk) until the charge current has dropped to 70% of the nominal value. This is followed by a fixed four-hour constant voltage phase, at the end of which a trickle charge phase follows. The charging voltage is controlled by the internal temperature sensor (-2mv/°C per cell). The full charge current is distributed over three outputs, each output delivering full power on its own when only one battery is connected

Different battery types can be used on the Centaur 12/20; the default setting refers to gel batteries. Other batteries (lead acid or agm) can be used after appropriate setting on the jog switch (lower left behind the front front panel)
