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 optimize 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 optimize 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 to prevent overcharging of the battery. After a deep discharge, the absorption time is automatically increased to make sure that the battery is completely charged.
• Prevent damage due to excessive gassing: BatterySafe mode. If, 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 rates of voltage increase once the gassing voltage has been reached.
• Less maintenance and aging when the battery is not in use: Storage mode. The storage mode kicks in whenever the battery has not been subjected to discharge for 24 hours. In the storage mode float voltage is reduced to 2.2V/cell (13.2V for 12V battery) to minimize gassing and corrosion of the positive places. 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.
• 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 fluctuation of battery temperature is expected. 
• Battery voltage sense. 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.
• Universal 90-265VAC input voltage range and suitable for DC supply (AC-DC and DC-DC operation). The charger will accept a 90-400VDC supply.
• Computer interface. Every Phoenix charger is ready to communicate with a computer through its RS-485 data port. Together with VEConfigure software, which can be downloaded free of charge and the data link MK3-USB, all parameters of the chargers can be customized.
