PROUSER DFC150 Bedienungsanleitung Seite 3

•
Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with a lead-acid battery.
•
A lead-acid battery can produces a short-circuit current high enough to weld a ring or
the like to metal, causing severe burns.

FEATURES
Automatic and Intelligent 4-Stage Charging Curve
The DFC150 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 DFC150 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.
