Charging Characteristics - Quick SBC 300 ADV PLUS FR Manual Del Usuario

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 batteries or
load connected. The battery charger has a loading characteristic of the IU o U 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 disconnected as it you
could cause damage to the equipment.

CHARGING CHARACTERISTICS

Charging occurs in 3 phases:
BULK PHASE (constant current)
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)
SORPTION 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)
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.

HALF-POWER MODE
If the supply voltage of the equipment drops under 97 Vac the battery charger will activate the "half
power" mode. In this mode the battery charger can supply, a maximum value half of the maximum no-
minal 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 generator or from a dock outlet with limited power
output.
The half power mode can be activated manually by using the remote LCD terminal (optional).
-
The batteries need more current than the battery charger can supply.
