The DSE9120 is a 7.3 Amp battery
charger suitable for 12 Volt leadacid batteries. The DSE9240 is a
3.5 Amp battery charger suitable
for 24 Volt lead-acid batteries.
Both chargers are designed to
be permanently connected to
automotive batteries, keeping
them charged to their maximum
capacity. The chargers can also
be used to supply a standing load
that is attached to a battery. To
improve reliability the chargers
do not include any moving parts.
The technology inside the
chargers has been designed to
avoid overcharging and
overloading.
The chargers will also continue
to operate during cranking and
running and have the ability to
accept multiple AC voltage
connections.

FEATURES
• Lightweight
• Compact design
• Can remain operational during
engine cranking and running
• Suitable for connection to a wide
range of AC voltages between
100V and 240V, 50Hz or 60Hz
• No moving parts
• Switch mode design
• Overload & short circuit protection
• LED charging indicator
• Convection cooling
• Minimum 80% efficiency
throughout full operating range

OPERATION
The charger has been designed to
supply current to a battery until the
battery terminal voltage is equal to
the set float voltage. After this it will
change to a trickle charge current.
When the battery voltage falls, due
to a load being applied and the
battery being discharged, the charger
will supply current to restore the
voltage of the battery to the float
voltage.
