Automatic voltage compensation
The charger compensates for voltage drop over the DC cabling by slightly increasing output voltage when the DC current increases. 

Adaptive 5-stage charge algorithm: bulk – absorption – recondition – float – storage
The Phoenix Smart Charger features our well-known ‘adaptive’ battery management system that can be preset to suit different types of batteries. The ‘adaptive’ feature will automatically optimise the charge 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 will be fully charged.

Preventing damage due to excessive gassing: the BatterySafe mode
If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, the charger will prevent damage due to excessive gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached 

Less maintenance and aging when the battery is not in use: the Storage Mode
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 a 12 V 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.

Also charges Li-ion (LiFePO₄) batteries
Charger on-off control can be implemented by connecting a relay or open collector optocoupler output from a Li-ion BMS to the remote on-off port.
Alternatively full control of voltage and current can be achieved with Bluetooth.

Fully programmable charge algorithm
The charge algorithm can be programmed with help of Bluetooth or the VE.Direct interface.
Three preprogrammed algorithms can be selected with the mode button.

Remote on-off
The remote on/off consists of two terminals: Remote H and Remote L.
A remote on/off switch or relay contact can be connected between H and L.
Alternatively, terminal H can be pulled high, or terminal L can be pulled low.

VE.Direct interface
For a wired data connection to a Color Control panel, PC or other devices.

Programmable relay
Can be programmed using the VE.Direct interface or a Bluetooth enabled device to trip on an alarm or other events.
