Charging Characteristics - Quick SBC 600FR Benutzerhandbuch

Once the equipment has been wired up, switch on the supply.
When power is delivered, all the indicator lights on the front control panel will come on, for a short time.
The battery changer will then switch over to the charge mode as required, by the batteries (or by the load)
connected.
The battery charger provides a IUoU charge. The SBC chargers can also be used as power supplies, i.e. when the
batteries are disconnected.
It is advisable to use this operating mode only when necessary, i.e., not as a standard use.
In any case, avoid connecting high inductive loads (i.e. high powered motors) with the batteries disconnected, as
this may cause, even if rare, severe damage.

CHARGING CHARACTERISTICS

The charge takes place through three stages:
Constant-current stage. The batteries need more current than that supplied by the
battery charger. The current is limited to the maximum output rating.
BULK
The charger may come into this stage during the switching on, when the batteries are flat or
high loads are connected.
Constant-voltage stage. The charger charges the batteries at a constant voltage of
14.1V (14.4V Gel) or 28.2V (28.8V Gel) for the 24V models, providing the currents needed.
ABSORPTION
The need of the current to the battery will trend downwards with the time going.
When the output current will be less than 18% of the maximum output rated current, the
equipment will turn to FLOAT.
Maintaince state of charging. The charger charges the batteries at a constant voltage of
13.5V (13.8V Gel) or 27.0V (27.6V Gel) for the 24V models. During this stage, the batteries,
when fully charged, will tend to absorb currents of nearly zero ampere.
FLOAT
This allows the charger to maintain the batteries charged at all times without overloads.
Turn from FLOAT to ABSORPTION takes place when the currents required exceed the
maximum output rating of the charger by 18%.
