Description

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. 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.

Features

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 fig. 2 below)

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 fig. 2 below).

Less maintenance and ageing when the battery is not in use: the Storage mode (see fig. 1 & 2 below)

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 12 V battery) to minimize 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.

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.

Universal 90-265 VAC input voltage range and also suitable for DC supply (AC-DC and DC-DC operation)

The chargers will accept a 90-400 V DC supply.

Computer interface

Every Phoenix Charger is ready to communicate with a computer through its RS-485 data port.
