A microprocessor senses the condition of the battery and controls the regulator to provide the
right current and voltage to the battery (charging characteristic). This will give the best effect
on charging and give the longest life to battery.
Charging characteristic:
Soft Start:
Initial battery test to determine battery condition. If the battery is severely
discharged, the charger will begin the Soft Start stage. Charging starts with reduced
current until the battery voltage reaches a normal condition for charge.
Bulk
: Major charging stage where the battery receives the majority of its charge. During
this stage, the battery brought to 75 - 80% of its charger. The charger delivers maximum
current until the terminal voltage has risen to the full charge level for normal battery.
Absorption:
Completes the charge up to virtually 100% at a constant voltage. The
current tapers off after reaching the minimum level.
Float:
Maintenance charging at the constant voltage, keeping the batteries at 100%
charge. Normal charging mode is time-limited (max 10 days) while the Float mode charges
indefinitely without damaging the battery.
LED display
The unit is built-in with LED display for showing charger status:
REVERSE –
RED LED – DC clamps are connected in reverse polarity.
FAULT -
RED LED – Battery Fault.
POWER
- YELLOW LED – the charger is connected to the 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 the 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 the higher voltage. A low temperature heightens the output voltage, and hot
condition is handled by the lower voltage.
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
