FUNCTIONS
• General
D250T is a 24V DC-DC battery charger for a dual battery system with a starter battery and
a service battery. D250T is designed to be used as an onboard charger, for charging and
maintaining a 24-volt service battery from the vehicle alternator when motor is running.
• Charging
D250T uses a 4-step automatic charging algorithm to charge the service battery with up to 10A
when a conventional alternator (constant voltage) is running.
• Starter battery under voltage protection
The charging process is automatically switched off when the engine is not running to prevent
discharge of the starter battery.
• Temperature compensation
The external temperature sensor will adjust the charge voltage according to actual temperature
of the service battery. The charge voltage is reduced at higher temperatures and is increased at
lower temperatures. The temperature sensor should if possible be attached to the Service Battery,
or as close to it as possible. (see figure 4)
• Battery separation
D250T separates the starter battery from the service battery when the engine is not running. The
battery separation protects the starter battery from being discharged, this eliminates the needs for
diodes and VSR relays.
• Service battery temperature protection
The external temperature sensor attached to the service battery is protecting the service battery
from high temperatures by switching off the charging process if the measured temperature rises
too high. The charger will automatically restart when the service battery temperature reduces to a
level level within the specified operating temperature.
• Equalizing the starter battery
In a 24V system, where we have two 12V batteries in series, the voltage in the two batteries can
be unbalanced, especially if there are 12V consumers connected to one of the batteries. When
the service battery is fully charged, the D250T will measure the voltage levels in both 12V starter
batteries. If there is a difference between the voltage in these two batteries, the D250T is will
equalize the voltage levels to increase battery performance and lifetime.
• Protects service battery from overcharging
D250T will not overcharge the service battery. When the service battery is fully charged D250T
will go into pulse charging mode to monitor and maintain the charge status battery. If battery
voltage drops too low the charging process will restart.
• SMARTPASS 120T
Fully compatible with SMARTPASS 120T to provide the ultimate power management solution for
dual battery systems.
• Remote status indicator lamp
There are no LED indicator lamps on the units themselves but there is a status signal lead attached
to the charger. This can be connected to a 24V lamp (Max. 2W) for remote indication of charger
status, in the driver’s cab or other places where indication is needed.

FUNCTIONS
• General
SMARTPASS 120T is a Power Management Solution which distributes, controls and maximizes
available energy from the vehicle alternator to service batteries and other consumers.
SMARTPASS 120T connects the service battery to the alternator/starter battery in order to split
charge and deliver up to 120A continuously to the service battery and parallel consumers.
• Split charging
SMARTPASS 120T connects the service battery to the starter battery when the alternator is
running, or when the starter battery voltage is kept above a set threshold by another power
source, for example an external battery charger.
• Battery separation
SMARTPASS 120T separates the starter battery from the service battery when the engine is not
running. The battery separation protects the starter battery from being discharged, this eliminates
the needs for diodes and VSR relays
• Service Battery guard (Deep discharge protection)
Turns off all the equipment connected to the SMARTPASS 120T consumer output when service
battery voltage is low, this protects the service battery from deep discharge and will extend
battery life. The consumer output will reconnect when service battery voltage has increased back
to a level within specified operating range.
• Critical consumers
If there are some consumers with low power consumption that must be prioritized (critical
consumers), they can be connected directly to battery. This will ensure they are always connected
to the service battery. Please note: by connecting consumers directly to the service battery, the
SMARTPASS 120T can no longer protect against deep discharge.
• Assigning current source priority
When the alternator is running, the SMARTPASS 120T will supply consumers with current directly
from the starter battery (alternator). This feature will maximize the charging efficiency when a
D250T is used in the system as no consumers will take any power from service battery.
• Dynamic overcurrent protection
SMARTPASS 120T can handle temporary inputs and outputs of up to 350A for fast charging. It
has an overcurrent protection and internal temperature monitoring to protect electronic circuits and
keep the electronics within safe operation.
• Smart Alternator
SMARTPASS 120T can also be used when vehicle is equipped with a smart alternator (with
variable charging voltage). This is activated by connecting the red smart alternator cable
according to the instruction in this manual.
• Overvoltage protection
The Alternator input is electronically overvoltage protected. If voltage from alternator is too high
SMARTPASS 120T will turn off the connection to service battery and consumers.
• Service battery temperature protection
SMARTPASS 120T is equipped with a temperature sensor to be attached to the service battery
pack. This protects the battery by switching off the connection between starter battery and service
battery if the service battery temperature is too high, i.e. not allowing charge from the alternator to
the service battery.
• Starter battery trickle charging
When the service battery voltage is higher than the starter battery, the SMARTPASS 120T will
trickle charges the starter battery by periodically connecting the service battery output to the
alternator input. This can be helpful to compensate for the self-discharge of the starter battery. It
is especially useful if another power source is feeding the service battery, for example a battery
charger.
• Compatible with D250T
To get the optimal dual battery management system the SMARTPASS 120T should be combined
with D250T DC-DC charger to get a stable, reliable and optimized charging system. D250T and
SMARTPASS 120T can together charge the service battery and provide the consumers up to
130A of power.
• Overvoltage protection
Alternator input is electronically overvoltage protected. If voltage from the alternator is too high
the SMARTPASS 120T will disconnect the connection to the service battery and consumers.
When voltage is back within the normal range SMARTPASS 120T will automatically open the
connections.

DEFINITIONS AND DESCRIPTIONS
STARTER BATTERY
A battery intended for the engine’s electric starter motor in automotive applications.
A starter battery should never be deeply discharged.
SERVICE BATTERY
Service battery is an auxiliary battery that will provide power to electrical equipment when the
vehicle motor is not running. This additional battery will prevent the starter battery to be being
drained and protect against a flat battery. Suitable deep cycle batteries should be used.
TEMPERATURE SENSOR
The D250T optimises the charge voltage by increasing the charge voltage at temperatures below
25°C/77°F and reducing it at temperatures higher than 25°C/77°F.
TEMPERATURE COMPENSATED CHARGE VOLTAGE
The charger will adjust the charge voltage according to service battery temperature. This can be
done by attaching the temperature sensor to the starter battery or somewhere close to the battery.
BATTERY TEMPERATURE PROTECTION
Protects the battery by switching off charging if the temperature rises too high.
FUSES
Fuses must be used for overload protection. Mount the fuses as close to each battery as
possible. Please see this instruction manual for recommended fuse sizes - see “CABLE AND FUSE
REQUIREMENTS” table.
WIRING
Please see this instruction manual for recommended cable length and sizes - see “CABLE AND FUSE
REQUIREMENTS” table.
CONSUMERS
Consumers should normally be connected to the consumer output terminal on the SMARTPASS 120T.
If battery voltage reaches a critically low level, the consumer output terminal is deactivated to protect
the service battery from being deeply discharged.
When the vehicle motor is running, non-critical consumers receive current from the alternator instead
of the service battery, for faster charging of the service battery.
If there are some consumers with low power consumption that must be prioritized (critical consu-
mers), they can be connected directly to battery. This will ensure they are always is connected to the
service battery. Please note: by connecting consumers directly to the service battery, the SMARTPASS
120T can no longer protect against deep discharge. A critical consumer could be a ticket system, life
support equipment, communication radio etc.
EQUALIZING (EQU)
In a 24V system where we have two 12V batteries in series the voltage in the two batteries can be
unbalanced, especially if there are 12V consumers connected to one of the batteries. The Equalizing
process is balancing the voltage level in the two batteries and ensures battery performance and
extends battery life.

INSTALLATION EXAMPLES
PREREQUISITES
A dual battery system, where the D250T
charges a service battery from the vehicle
alternator when the motor is running.
Use this installation when the priority is to charge
and maintain the service battery with the opti-
mum charge voltage, and when there are no, or
minor, parallel consumers that need power when
the vehicle is running. Parallel loads will reduce
available charge current and extend charging
times. If you are charging parallel consumers,
we recommend you also install a SMARTPASS
120T. See installation example #3.
Use this installation when:
– Priority to charge the service battery with
optimum voltage.
– No or minor parallel consumers
to Service battery.
– Service battery capacity up to approx.
150Ah, for larger batteries the charging time
will be too long.
1. Small service battery
PREREQUISITES
SMARTPASS 120T connects the service battery
with the alternator/starter battery in order to split
charge and supply up to 120A continuously to
the service battery and parallel consumers.
Use this installation when the priority is to
manage larger consumers parallel to the service
battery that require power when the vehicle is
running.
One basic condition required for this installation
is that the alternator can deliver sufficient voltage
to supply equipment and split charge the service
battery. If the alternator is not able to provide
enough voltage to fully charge the battery, the
SMARTPASS 120T will not either. In this case,
we recommend that you also install the D250T
DC/DC charger.
Connect the cabling from the starter and service
batteries respectively to the SMARTPASS 120T
and not to the D250T.
Use this installation when:
– Large electrical consumers parallel
to service battery.
– Alternator able to provide the desired voltage
– Power management is priority.
– Larger service battery capacity up to 800 Ah.

PREREQUISITES
A dual battery system where the D250T,
together with SMARTPASS 120T, will charge
the service battery when the vehicle motor is
running. and It will also manage available
power from the alternator to both the service
battery and parallel consumers.
This installation will give a system that both can
manage large parallel loads and at the same
time charge maintain the service battery, with
the optimum voltage for a 24V dual battery
system. The battery charging will be more
efficient and shorter as we are getting access to
a higher current initially, parallel consumers will
be powered directly from alternator.
Use this installation when:
– Large electrical consumers parallel to service
battery need power when the motor is
running.
– Need onboard charging and maintenance of
the service battery.
– Large service battery capacity (up to 800 Ah).
– A safe and reliable onboard charging and
power management system is required.
An AC/DC battery charger can be connected to
the service battery as complement to D250T and
SMARTPASS 120T. This can be useful if:
• Power from the alternator, when the engine
is running, is not enough to fully charge the
service battery. Additional charge is needed
to fill the battery up to 100%.
• Maintenance charging of the service battery
(and starter battery) during long time storage
of vehicle. The AC/DC charger will ensure
that the batteries are fully charged when the
vehicle should be used again.
• You will have access to AC power at your
destination. The AC/DC charger will charge
the battery and act as power supply for
connected consumers.
• Select the size of AC/DC battery charger
suitable for the size of the battery and all
consumers that are active whilst charging. For
example: A 10A charger will not charge a
battery at all if you have a 10A light turned
on.
Tips: If the starter battery needs charging, it
is possible to connect the AC/DC charger
to the starter battery and the D250T and
SMARTPASS120T will charge and maintain to
the service battery in at the same time.

CHARGING PROGRAM D250T
The D250T will charge the service battery in 4 steps - Bulk, Absorption, Float and Pulse. The last step,
Pulse maintenance, means that the D250T monitors state of charge of the service battery, keeping
the battery fully charged without risk of overcharging. During this step, the D250T will also monitor
state of charger of the starter battery set, sending out voltage to each battery separately to equalize
the two 12V batteries – this will significantly extend battery life. Equalization ends when the service
battery needs charging or when the two batteries in the starter battery set have the same voltage.
STEP 1 BULK
Charging with maximum current until approximately 80% battery capacity.
STEP 2 ABSORPTION
Charging with declining current to maximize up to 100% battery capacity.
STEP 3 FLOAT
Maintaining the battery voltage at maximum level by providing a constant voltage charge.
STEP 4 PULSE
Maintaining the battery at 95–100% capacity. The charger monitors the battery voltage and
gives a pulse when necessary to keep the battery fully charged.
