FEATURES
Automatic and Intelligent 4-Stage Charging Curve
The DFC530N is controlled by a 12-bit AD microprocessor with 4-stage charging characteristic
for charging batteries automobiles, motorcycles, snow mobiles, tractors, personal watercraft,
boats etc.
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 charger will begin the Soft Start stage. Charging starts with reduced current
until 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 DFC530N 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 the current reached the minimum level.
Float: Maintenance charging at constant voltage, keeping the batteries at 100% charge.
•
Normal charging mode is time-limited (max 10 days) while Float mode chargers
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 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
