BATTERY TYPE SELECTION
The battery charger can be set to optimize the charge according to the type of battery used.
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: select the battery type only when the battery charger is switched off.
FIG.2
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 procedure takes place 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 or
to a lower value if factors which determine a power reduction of the device are present. The battery charger can enter
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 supplying the current needed when the
current requested is greater than the transition threshold between ABSORPTION and FLOAT and less than the maximum
output value or at a lower value if factors which determine a power reduction of the device are present.
FLOAT phase (maintenance)
The battery charger charges the batteries at constant FLOAT voltage when the current required is less than the transition
threshold between ABSORPTION and FLOAT. In this phase, as the batteries reach maximum capacity, they will tend to
absorb increasingly low current. This float phase will allow the batteries to be on charge without risking overload.
