IU0U automatic charger Use of the IU0U automatic charger

U phase
If the current decreases to 10% of the rated current or if the time limit of 4/8
hours is exceeded, then the charger switches over to economy charging
(13.8 V or 27.6 V) (U phase).
Note
In the case of chargers with double charging or three-fold
charging connection there exists the possibility of charging
batteries separately from each other. The outputs are separated
internally via diodes. The weaker battery is always first set to the
charging level of the stronger battery. The charging characteristic
is the same as described above.
Attention
The maximum battery capacity (see Chapter „Technical data“ on
page 47) should not be exceeded in order not to influence the
functions of the individual charging phases.
Only for units with temperature sensors that are optionally available.
Adapting the charging voltage dependent on the battery temperature. A
temperature sensor can be connected for to provide the optimum charging
functioning. The charging voltages, as can be seen from the diagram, are
raised or dropped dependent on the battery temperature.
