Technical Data
Power supply
AC voltage 230 V / 50 Hz, single-phase
Range approx. 195 V – 250 V / 50 – 60 Hz
Output current (charging current battery)
Charging current max. 30 A, arithmetic mean value, electroni-
cally controlled according to the IUoU charging reference line
Output voltage
DC voltage 12 V
Charging process
Automatic
Automatic switching (main charging process)
OFF at a battery voltage of 14.4 V, charging current < 27 A
Automatic switching (afterloading phase)
10 hours constant 14.4 V for gel batteries / AGM
4 hours constant 14.4 V for liquid electrolyte batteries
Automatic switching (trickle charging)
Trickle charging constant 13.8 V
Temperature-dependent control (optional)
The values of the automatic switching device refer to a battery
temperature of 20 °C. If a temperature sensor is used with the
battery, these values will vary in accordance with the battery
temperature.
High temperature –> reduction of the threshold values
Lower temperature –> higher threshold values

Rectification
Check all connections from
the automatic charger to
the battery, ensure that they
are connected to the right
terminals. Unplug the cold
device plug on the device
then plug in again. Check all
fuses and the mains supply
connection.
The device is too warm, en-
sure better ventilation of the
device.
