Soft start
tests the battery condition. Severely discharged batteries need the soft start step. The
charging starts with a reduced current until the voltage reaches 10V.
Bulk
is the main step where most of the charge is returned (60-80%). The charger delivers maximum
current until the terminal voltage has risen to the set level of 14,2V for Normal battery selection and
14.0V for Gel battery selection.
Absorption
completes the charge up to virtually 100% at a constant voltage. The current tapers off
after the current reached the minimum level.
Float is maintenance charge at constant voltage, keeping the batteries at 100% charge. Normal
charging mode is time-limited (max. 10 days) while Supply mode goes on indefinite without damaging
the battery.
SPECIAL FEATURES
Temperature Control Fan
To protect the charger from overheating, a fan is included for heat dispensation. Also to
increase the life span of the fan, a sensor will control the on off the fan, where the fan
will not use when the HFC is not in a hot condition.
Temperature Compensation
A sensor will automatically adjust the charging voltage if the temperature deviates
between -20ºC to +50ºC. At a high temperature environment the unit lowered the output
voltage and at a freezing condition, the unit will adjust a higher output 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 the true input voltage to the battery and adjust the output voltage of the
unit accordingly. This will maximize the charging efficiency.
Buzzer Warning
A built in buzzer will help to warn the user when connect the clamps to the battery
wrongly.
