Victron Phoenix Charger 12/30 (2+1) 120-20V

Description

Victron Phoenix Charger 12/30 (2+1) 120-20V

Adaptive 4-stage charge characteristic: bulk - absorption - float - storage. Two full rated outputs and one 4 Amp output. Universal input 90-265V, 50/60Hz. The Phoenix charger features a microprocessor controlled adaptive battery management system that can be pre-set to suit different types of batteries. The adaptive feature will automatically optimise the charge process relative to the way the battery is being used.

Adaptive 4-stage charge characteristic: bulk - absorption - float - storage 

The Phoenix charger features a microprocessor controlled adaptive battery management system that can be preset to suit different types of batteries. The adaptive feature will automatically optimise the process relative to the way the battery is being used.

The right amount of charge: variable absorption time:
When only shallow discharges occur (a yacht connected to shore power for example) the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged.

Preventing damage due to excessive gassing: the BatterySafe mode: (see figure 2 in specs).
If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, the Phoenix charger will prevent damage due to excessive gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached (see the charge curve between 14,4 V and 15,0 V in figure 2 in specs).

Less maintenance and aging when the battery is not in use: the Storage mode (see figure 1 & 2 in specs).
The storage mode kicks in whenever the battery has not been subjected to discharge during 24 hours. In the storage mode float voltage is reduced to 2.2 V/cell (13.2 V for 12V battery) to minimise gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to _equalize_ the battery. This feature prevents stratification of the electrolyte and sulphation, a major cause of early battery failure.

Three outputs to charge 3 battery banks: 
The Phoenix chargers feature 3 isolated outputs, of which 2 can carry the full output current. The third output, limited to approximately 4A and with a slightly lower output voltage, is intended to top up a starter battery.

To increase battery life: temperature compensation:
Every Phoenix charger comes with a battery temperature sensor. When connected, charge voltage will automatically decrease with increasing battery temperature. This feature is especially recommended for sealed batteries and/or when important fluctuations of battery temperature are expected.

Battery voltage sense: 
In order to compensate for voltage loss due to cable resistance, Phoenix chargers are provided with a voltage sense facility so that the battery always receives the correct charge voltage.
