Waeco PerfectCharge IU152A Installation And Operating Manual page 52

Using the IU0U automatic charger
U Phase
If the current falls to 10% of the rated current or if the time limit of 8/16 hours
is exceeded, the charger switches to trickle charge (13.8 V or 27.6 V)
(U phase).
NOTE
I
The chargers with two or three charging connections enable batter-
ies to be charged separately. The outputs are separated internally
via diodes. The charge level of the weaker battery is always
brought to the level of the stronger battery first. The charging char-
acteristics are as described above.
NOTICE!
A
The maximum battery capacity (see "Technical data" on page 55)
must not be exceeded since that would affect the individual charg-
ing phases.
Devices with temperature sensors (accessory)
The charging voltage is adjusted according to the battery temperature. A
temperature sensor can be connected for an optimum charging function. The
charging voltage is increased or reduced according to the battery tempera-
ture (see diagram):
16/32 V
15/30 V
14/28 V
13/26 V
12/24 V
