OPERATION
When the battery charger is switched on for a short period, all the LEDS on the front panel will light
up. After that the battery charger will place itself in the optimum charging mode to best suit the bat-
teries or load connected. The battery charger has a loading characteristic of the IUoU type.
The SBC battery chargers can also be used as a power supply, that is, with batteries disconnected.
We suggest you use the battery charger in this mode only occasionally and not for ordinary use.
However, avoid connecting high inductive loads (e.g. high powered motors) with the batteries discon-
nected as it you could cause damage to the equipment, even if rare to happen.
CHARGING CHARACTERISTICS
Charging occurs in 3 phases:
BULK phase (constant current) - The batteries need more current than the battery charger can sup-
ply. Current is limited to the maximum rated output. 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 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 charger will change to the FLOAT phase.
FLOAT phase (maintenance) - The battery charger charges the batteries at the constant FLOAT volt-
age. 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 overload-
ing. The next step to the ABSORPTION phase occurs when the demand for current goes over 20% of
the maximum output value.

HALF-POWER MODE
If the supply voltage of the equipment drops under 195 Vac (or 97 Vac for the Full Range models) the
battery charger will activate the "half power" mode. In this mode the battery charger can supply, a
maximum value half of the maximum nominal output current. In this way you can reduce the current
absorption from the AC supply. This feature is useful when the battery charger is supplied via a gen-
erator or from a dock outlet with limited power output.
The half power mode can be activated manually by using the signal found in the signal control con-
nector.
