The MA series lead-acid battery charger is professional design according
to the power battery of electric vehicles equipment. It uses the
advanced soft switch technology, with small size, high conversion
efficiency, running full loading for a long time, stable output current,
high reliability, long service life, easy operation,etc. With
short-circuited protection, low-voltage protection, over-heated
protection. The long delay digital counter can ensure the battery from
the constant voltage to the float charge reliably every time.
Specification
Four-phase charging mode
Pre-charge
mode: In order to protect the battery and extend its life, the
battery's internal resistance is too large or voltage is too low because
the discharged time is too long or it is not used for a long time, the
charger will supply low output current for the battery automatically.
When voltage of the battery rises to the given voltage value, the charge
mode will turn to constant current charge mode automatically.
Constant current mode: The charger supply constant charge current for the battery.
Constant
voltage mode: Using the pulse width modulation(PWM) tech to control the
charging current and output voltage of the charger which ensure the
battery is fully charged and avoids over charging.
Floating
charge mode: When the voltage of the battery is approaching the value
of the constant voltage mode, and the current cut down to the given
current gradually, that means the battery power is full, then the pilot
lamp will turn green and the fan will stop working. The charger will
turn the mode into floating charge mode automatically. At this moment,
the battery can be stopped charging or keep on floating charge for half
an hour
