Victron Centaur Charger 12/20 analogue battery charger 20A 12V

Victron Centaur Charger for 12 V Batteries

The new Centaur battery charger range from Victron Energy has been designed for worldwide use.
Compliance with general requirements and input/output specifications are the main features of this new product range, which was designed by the renowned Dutch manufacturer. It was designed to meet both the requirements of the CE marking for Europe and the UL marking for the United States.
The Centaur range automatically accepts an input range from 90 to 265 VAC 50/60 Hz. This means that the devices can be used anywhere in the world.

Unlike other devices that have a universal input power, the Centaur range maintains the full output power within the specified range.
The Centaur model also works at an input power of 90-400 VDC. This makes it a DC-DC charger, perfectly suited for an electronic diesel system. Among other things, the model features a fully automatic three-stage charging profile, which ensures that the batteries are fully charged every time, as well as three separate charging outputs for equipment with multiple batteries, making it suitable for most typical installations.

Resilient device, quality without compromise
The aluminum enclosure with epoxy powder coating, drip protection against condensation and stainless steel mounting hardware withstand the harshest requirements such as heat, moisture and saline atmospheres.
The circuit boards are securely protected against corrosion by an acrylic coating. Temperature sensors ensure that all power components operate within specified limits and, if necessary, automatically reduce the output current under extreme conditions.

Universal 90 to 265 Volt input
All models operate without special settings in a voltage range of 90 V to 265 V at both 50 Hz and 60 Hz. This makes worldwide use possible, regardless of the voltage and frequency range of the local grid.

Three outputs, each with full output current
Three separate outputs for the simultaneous charging of three battery sets. Each output delivers the full current.

Three-stage charging profile with temperature compensation
Centaur initially charges at constant current (bulk) until the charging current has dropped to 70% of the rated value
Then follows a preset four-hour constant voltage phase, after which a maintenance charging phase follows. The charging voltage is regulated via the internal temperature sensor (-2mV/°C per cell).
With a DIP switch, the optimal charging voltage values can be set for the respective battery types (e.g. wet lead-acid battery, gel battery or AGM battery).
