Victron Phoenix Charger 12/50 (2+1) 120-240V Battery Charger 50A 12V

Phoenix 12/50 Battery Charger by Victron: 50A Charging Current for 12V Batteries

Adaptive four-stage charging characteristic:
Constant current ("bulk") phase, constant voltage ("absorption") phase, float voltage ("float") phase, storage voltage ("storage") phase

The microprocessor-controlled 'adaptive' battery management system of the Phoenix charger can be adapted to different battery types. 'Adaptive' means that the charging characteristic is automatically adjusted to the type of battery usage.

The right amount of charge: adjusted constant voltage time
For low battery discharge (e.g. a yacht connected to shore power), a short constant voltage phase is chosen to avoid overcharging.
After a deep discharge, the constant voltage phase is automatically extended to ensure that the battery is fully charged.

Prevention of damage due to excessive gas evolution: the battery protection mode
To shorten the charging time, the highest possible charging current together with a high constant voltage was selected. However, to prevent excessive gas evolution towards the end of the constant current phase, the Phoenix charger limits the rate of voltage increase after the gassing voltage has been reached.

Less maintenance and aging during battery idle: the storage mode
The storage mode is activated whenever no discharge has occurred within 24 hours.
In storage mode, the float charge voltage is then lowered to 2.2 V/cell (13.2 V for a 12 V battery) to minimize gassing and corrosion of the positive plates.
Once a week, the voltage is raised to the level of the gassing voltage. This achieves a kind of equalization charge that prevents electrolyte stratification and sulfation - the two main reasons for premature battery failure.

To extend battery life: Temperature compensation
A temperature sensor is included with every Phoenix charger. The temperature sensor ensures a decreasing charging voltage as battery temperature increases.
This is particularly important for gel batteries or if constantly high temperature fluctuations are expected.

Battery voltage sensor
To compensate for voltage losses due to cable resistance, the Phoenix charger has a voltage sensor in the charging circuit, so that the battery always receives the correct charging current.

Universal 90-265 V AC input voltage range:
also suitable for DC power supply (AC-DC and DC-DC operation).
The chargers accept a 90-400 V DC power supply.

Computer interface
Each Phoenix charger can exchange information with a computer via its RS-485 data port.
Together with the VEConfigure software, which can be downloaded free of charge from the website www.victronenergy.com, and with the Data Link MK1b (additional accessory), all parameters of the charger can be individually adjusted.
