SELECTION OF THE CHARGING MODE
The battery charger can be set to optimize the charge according to the type of battery used, either liquid, gel, AGM.
The selection of the type of charge is made via the rotary switch placed in the terminal board area, as indicated in fig. 2.
WARNING: check the charge mode. Incorrect selection could cause shorter battery life or lengthen the charging time.

OPERATION
When the battery charger is switched on, it automatically selects the optimum charge mode to best suit the batteries
or load connected. The battery charger has a loading characteristic of the IUoU type.
CHARGING CHARACTERISTICS
Charging occurs in 3 phases:
BULK phase (constant current) - The batteries need more current than the battery charger can supply. Current is
limited to the maximum rated output. The battery charger can enter in this phase during start-up, when the batteries
are low or when a high load is connected.
ABSORPTION phase (constant voltage) - The battery charger charges the batteries at a constant ABSORPTION voltage
and at the current they need. The current needed by the batteries will tend to diminish over time. When the required
current is less than 20% of the maximum output value, the battery charger will change to the FLOAT phase.
FLOAT phase (maintenance) - The battery charger charges the batteries at the constant FLOAT voltage. In this phase,
as the batteries reach maximum capacity, they will tend to absorb current close to zero Ampere. This float phase will
allow the batteries to be on charge without the risk of overloading. The next step to the ABSORPTION phase occurs
when the demand for current goes over 20% of the maximum output value.
