LED display
The unit is built with LED display for showing charger status:
REVERSE –
RED LED – alligator clamps are connected in reverse polarity.
FAULT -
RED LED – Battery Fault.
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.
3 x 7 Segment LED Main display
– Indicating charging current, battery voltage and
charging %
Memory Function
If black out or the AC plug is disconnected from the mains supply, the battery charger will turn
to memory mode and “- - -” illuminates on LED display. The charging mode and status will be
recorded in the charger’s memory. Once power is resumed, MB-3623 will resume the charging
process at the previous mode.
Remark:
-
Memory function works on the condition that unit is connected with a
battery which is at or over 6V.
-
If prolonged black out is expected, please disconnect the unit from both mains
and battery to reset the memory function.
NOTE:
The memory function consumes power from battery and may run it flat.
Temperature Compensation
A sensor will automatically adjust the charging voltage if the temperature deviates between –
20°C to +50°C. At a high temperature environment, MB-3623 lowers 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 alligator clamps of the
unit can be lower than the charger output voltage. A special circuitry inside will monitor the
true input voltage to the battery and adjust the output voltage accordingly. This will maximize
the charging efficiency.
Reverse-polarity protection
This unit offers reverse-polarity protection, the RED “REVERSE” LED will illuminate, the buzzer
will warn the user and the charging process will not start. If this happens, unplug immediately
from mains, connect the red alligator clip to positive (+) battery post, and black alligator clip
to negative (-) post, then plug into the mains power and the charging process will start.
