•
FAULT - RED LED – Battery Fault.
•
POWER - YELLOW LED – The charger is connected to mains power.
•
CHARGING – AMBER LED – The charger is charging to the battery.
•
FULL - GREEN LED – The battery is fully charged and the charger is in maintenance
mode.
Temperature Compensation
A sensor will automatically adjust the charging voltage if the temperature deviates from
– 20°C to +45°C. A high temperature environment will lower the voltage and freezing
condition is handled by higher voltage. A low temperature heightens the output voltage,
and hot condition is handled by lower voltage.
A temperature sensor has been built in the
housing of the cable connector to maximize the
accuracy of this feature. The temperature is
best measured on or very close to the
battery.
Voltage compensation
Because of some voltage drop in the cables, the actual voltage at the clamps of the
battery can be lower than the charger output voltage. A special circuitry inside the unit
will monitor the true input voltage to the battery and adjust the output voltage of the
unit accordingly. This will maximize the charging efficiency.
Reverse-polarity protection
This unit offers reverse-polarity protection, the RED "REVERSE" LED will illuminate and
the charging process will not start. If this happens, unplug immediately from mains,
connect the red crocodile clip to positive (+) battery post, and black crocodile clip to
negative (-) post, then plug into the mains power and the charging process will start.
Short-circuit protection
Should you accidentally touch the crocodile clips together whilst the mains power is on,
the unit will not perform charging. Unplug from mains, disconnect and start the process
again being careful not to touch the clips together.
Cable connector
The DFC900 has two options for
connecting the unit to the
battery. Via the intelligent cable
connector you can select witch connection you want to use:
•
Crocodile clamps for easy and flexible use.
•
O-ring connectors for permanent fixation on your battery.
Hanging clip
The DFC900 is supplied with a (removable) steel hanging clip.
With this clip it is easy to hang the charger somewhere in
your car or garage during charging or for storage.
