FEATURES
Automatic and Intelligent 9-Stage Charging Curve
PSD008 is controlled by a microprocessor with 9-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.
Battery Test and Precharge (Stage 1)
: Check the battery voltage to make sure battery
connections are good and the battery is in a stable condition before beginning the charge
process.
Desulphation (Stage 2):
Pulsing current and voltage, removes sulfate from the lead plates
of the battery restoring the battery capacity.
Soft Start (Stage 3):
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 (Stage 4):
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.
Adsorption (Stage 5):
Completes the charge up to virtually 100% at a constant voltage.
The current tapers off after the current reached the minimum level.
Recondition (Stage 6):
In “Recondition” mode, the battery is charged by higher voltage
to recondition the sulfate of the battery to save battery life.
Analysis (Stage 7):
Tests if the battery can hold charge. Batteries that can not hold charge
may need to be replaced.
Float (Stage 8):
Low constant voltage, minimal charge current, battery is fully charged.
Pulse (Stage 9):
Maintaining the battery at 95-100% capacity. The charger monitors the
battery voltage and gives a pulse when necessary to keep the battery fully charged.
