2. DESCRIPTION
2.1 The Titan battery charger
The Titan battery charger is a fully automatic charger for 24V or 48V batteries and is
powered by a mains voltage of 230Vac, 50Hz. It charges the battery according to the IUoUo
characteristic, which is a 3-stage charging characteristic. This characteristic is shown in
illustration 1. While charging, the Titan continuously measures the battery voltage and
current and bases the charging voltage and current on the measured values.
Type Boost voltage Float voltage Minimal
voltage
24V / 80A 28,5 Vdc 26,5 Vdc 25 Vdc
24V / 100A 28,5 Vdc 26,5 Vdc 25 Vdc
24V / 100A 3-Ph 28,5 Vdc 26,5 Vdc 25 Vdc
48V / 50A 57 Vdc 53 Vdc 50 Vdc
Assuming that the battery is discharged, the Titan charger starts charging in the boost-charge
mode. In this mode the battery is charged until the battery voltage reaches the boost voltage.
At this point the battery is charged to approximately 80% of its maximum capacity. This is
the end of the boost-charge mode and the Titan charger automatically switches to the
equalize-charge mode.
During the equalize-charge mode the charging voltage stays the same as the boost voltage but
the charge current slowly decreases. The duration of this mode is pre-selectable to 4, 8 or 12
hours. The standard time of the equalize-mode is 4 hours. After this time the Titan charger
automatically switches into the float-charge mode.
In the float-charge mode the charge voltage changes into the float voltage and the charge
current continues to decrease. This mode lasts for 20 hours.
After the float-charge mode the charger returns to the equalize-charge mode for 30 minutes,
this is to compensate for the normal leakage or self discharge of the battery.

8 Manual Titan
The Titan charger can remain connected to the battery continuously, without gas formation
taking place, caused by overcharging. It is not necessary to disconnect the battery from the
charger during long time storage, for example during the winter storage of a ship. The Titan
charger will keep your battery in optimum condition under all circumstances and will prolong
the lifetime of your battery.
A parallel load connected to the battery can cause a voltage drop. The Titan charger
automatically switches into the boost-charge mode when the battery voltage drops below the
minimal voltage.
The Titan charger is equipped with a separate starter-battery connection to charge an extra
battery, like a starter-battery. You can use this battery for starting machines, like a boat
engine for this application.
The Titan charger has a stabilised output voltage. Therefore the Titan charger can also be
used as a DC power supply in applications where no battery is present.
2.2 The battery
The Titan charger can charge various batteries. The recommended battery capacity is
indicated in the table below:
Type Recommended capacity
24/80 300 - 600 Ah
24/100 500 - 1000 Ah
24/100 3-Ph 500 - 1000 Ah
48/50 200 - 400 Ah
The charge voltages of the Titan charger are factory set. Most battery manufactures
recommend these charging voltages for optimal charging of 24V or 48V lead-acid batteries.
It is possible to charge different types of batteries, like traction batteries. To charge these
batteries the charging voltages of the charger have to be changed. Contact your Victron
Energy dealer or battery dealer for more details about the recommended charging voltages.

Manual Titan 9
2.3 Protection
The battery charger is safe to use due to its robust design and its internal electronic
protection. This chapter describes the various internal electronic protective devices.
Maximum charge current protection
 The battery charger provides a maximum charge current of 50A for the 50A charger,
80A for the 80A charger, or 100A for the 100A charger. This level is electronically
limited and is factory set.
 The maximum output current can also be limited by using an external potentiometer-
panel, the Victron Energy COV panel.
Short circuit protection
 The charger output is protected against short-circuits. The short-circuit current is
electronically limited at 50A, 80A or 100A, according to the model. In this condition the
output voltage approaches 0 Volt. The battery charger resumes normal operation when
the short circuit is removed.
 The short circuit current can also be reduced by the Victron Energy COV panel.
Input protection
 The charger mains-input is protected with a fuse.
 The charger will not be damaged by using input voltage between 0 and 300 Vac.
 The charger will not be damaged by using input voltage frequency between 0 and 65
Hz.
Over voltage protection
 The charger switches off automatically when the battery voltage becomes higher than the
over voltage value. The charger switches back on when the battery voltage becomes less
than the raise value. See the table below.
Model Over voltage value Raise value
24V 35,5 Vdc 33,5 Vdc
48V 68,1 Vdc 64.1 Vdc
 The charger output is protected with a fuse.
Starter battery protection
 The output current of the starter battery output is electronically limited at 4A. The starter
battery output is also protected against wrong connections by means of a 10A fuse.

10 Manual Titan
Temperature protection
 The internal temperature of the charger is measured continuously. However, due to a
high ambient temperature outside the cabinet the temperature within the battery
charger can rise. When the external temperature of the battery charger becomes higher
than 40°C, the output current decreases and the Failure led flashes.
 Before the internal temperature becomes too high due to extreme conditions the
charger switches off and the Failure led illuminates continuously. The charger
resumes operation when the internal temperature is restored within limits.
Voltage sense protection
 When the voltage sense facility is used the charger automatically decreases the output
voltage when the voltage loss over the battery cables is more than 2 Volt in total.
Battery watchdog timer
 The charger is equipped with a battery watchdog timer. This timer measures the
duration of the boost mode. The moment the boost mode lasts longer than 10 hours,
the charger will switch to float mode. The charging voltage will then become the float
voltage. In this way it is prevented that a defective battery is needlessly charged with a
high charging voltage.

Manual Titan 11
3. DIRECTIONS FOR USE
3.1 Installation
Find a dry and well-ventilated area to mount the Titan charger and battery. Keep the distance
between the charger and the battery less than 6 meters.
The charger may be wall or floor mounted. Mounting on a wall improves the air circulation
within the charger cabinet and will prolong the lifetime of the battery charger.
The holes for the mains cable, the battery connections, the remote connections and the earth
connection are located at the bottom of the battery charger housing, see illustration 2.
Connecting earth
Connect the earth screw to a real earth-point. Connections to earth have to be according to
applicable safety standards.
 On a ship: Connect the earth screw to the earth plate or to the hull of the ship.
 On land: Connect the earth screw to the earth of the mains.
 Mobile applications (a vehicle, a car or a caravan): Connect the earth screw to the frame
of the vehicle.
Connecting the battery
The connections between the Titan charger and the battery are essential for a good operation
of the charger. Therefore the battery connections need tightening well. It is important to use
short and thick battery cables to minimise the voltage losses in the cable. Cable resistance
decreases accordingly as the cables become shorter and thicker. Therefore it is not
recommended to use cables longer than 6 meters. The table below shows the recommended
cable core thickness.
Type core diameter of cables until 1,5m core diameter of cables between 1,5m and 6m
24/80 16 mm225 mm2
24/100 35 mm250 mm2

3.2 Operation
Located on the front of the Titan charger are an on/off switch and three rows of leds, as
shown in illustration 5.
The battery charger can be switched on and off with the on/off switch.
The “output voltage” leds indicate the output voltage value.
The “output current” leds indicate the output current value.
The other leds indicates the state of the charger.
The operation sequence:
Switching the charger on with the on/off switch results in the following:
 The “on” led will flash for about 2 seconds. In these first 2 seconds the charger reads all
input signals and calculates the necessary output voltage. After 2 seconds the charger
will switch on and the “on” led illuminates.
 According to the condition of the battery the charger will start in the boost-charge mode
or at float-charge mode. If the battery is not full the “boost” led illuminates and the
charger will start boost-charging the battery.
 A dip switch can be used to set the charger so that it will always start charging in the
boost mode, irrespective of the condition of the battery.
 When the battery voltage has reached the boost voltage the charger will change into the
equalize-charge mode and the “equalize” led illuminates. This mode will last for a pre-
selectable time of 4, 8 or 12 hours.
 After this time the charger will enter the float-charge mode and the “float” led will
illuminate.

4.1 Permanent boost-charge
In some cases, for example when the battery is almost empty, it is recommended to permanent
boost-charge the battery for 10 hours. Do not permanently boost-charge sealed lead-acid
batteries. Contact your Victron Energy dealer or battery dealer for more information on
charging the battery.
To set the charger into the permanent boost-charge mode :
 Place the DIP switch number 8 “R boost” to the left. In this mode the
battery is being charged to the boost voltage.
 Do not permanent boost-charge the battery for longer than 10 hours
as this can cause long term gas formation in the battery and will
damage the battery.
 While a battery is being boost-charged, check the water level of the
battery frequently and if necessary add distilled water to the battery.
4.2 Adjusting the charge voltage
The battery charger has a factory set float and boost voltage. The boost-voltage is always
higher than the float-voltage. These charging voltages are the recommended values from
almost every battery manufacturer. Before adjusting the charge voltage disconnect the
temperature sensor and/or the voltage sense wires.
To change the float-voltage:
 Remove all batteries and other users that are connected to the output of
the battery charger.
 Plug the AC plug into the mains and switch on the charger.
 Place DIP-switches 7 “Eq2” and 6 “Eq1” to the left position, this will
reduce the equalize time to 0 hours. The charger switches into the
float-charge mode.
 Place DIP-switch 4 “fine” to the left position in order to accurately
adjust the output voltage.
 Measure the float-voltage on the charger output by using a precision
voltage meter.
 Adjust the float-voltage by turning the “V float” potentiometer until the
recommended voltage is reached.
 Correct the equalize time by moving DIP-switch 7 “Eq2” and 6 “Eq1”.
 Place DIP-switch 4 “fine” to the right position. In this position the
output voltage is less sensitive to influence of temperature.
