Using the rectifier function of the automatic charger

7 Using the rectifier function of the
automatic charger
The IU0U automatic charger can be used as a 12-V power supply unit, pro-
vided the maximum power consumption (8 A) of the consumers does not ex-
ceed the rated power of the IU0U automatic charger (Fig. 4 A, Page 4). It
is recommended to connect the battery as well (Fig. 4 B, Page 4). The con-
sumers should be connected directly to the battery. This applies in particular
to consumers with high peak currents (e.g. high start-up currents).
Caution!
In parallel operation (consumers and battery), the maximum con-
sumer current must be lower than the rated current of the IU0U au-
tomatic charger, since otherwise the battery will discharge.
8 Charging process of the automatic
charger
I phase (Fig. 5 A, Page 4)
The empty battery is charged with constant current of 8 A at the beginning of
the charging process. The green "Charging" LED goes on.
U0 phase (Fig. 5 B, Page 4)
The phase of constant charging voltage with decreasing charging current be-
gins once the charging voltage is at approximately 14.4 V.
U phase, (Fig. 5 C, Page 4)
The IU0U automatic charger switches to the lower retention voltage of 13.6 V
if the charging current falls below 1 A or the maximum charging time
(15 hours) is exceeded. The battery is fully charged, the green LED goes out.
