The temperature correction of the end-of-charge voltages is --20 mV per de-
grees of temperature increase (in relation to 25
C) or +20 mV per degrees
of temperature decrease (compensation range 0 to 45
C U
max
14.9V; the
upper voltage limit at 14.9V is in consideration of the maximum input voltage
of consumers connected).
IMain charge with maximum 18 A charging current, electronically limited, up
to end-of-charge voltage. Start of charge also for completely discharged bat-
teries.
Automatic switchover to full charge with constant charge voltage (see table
above). The duration of the full charge phase is based on the battery type
and is set on the device.
Automatic switchover to trickle charging with constant voltage. In the trickle
charge phase, a constant voltage is applied to the charger module output.
The battery is now fully, or virtually fully, charged.
If the charger remains continually connected to the mains after the 3rd
phase is reached (U, trickle charging) without the battery being loaded ap-
preciably, the charger switches to standby mode after several days. Refresh
cycles are run continually.
For mains operation, the starter battery is also charged (with a maximum
charge current of about 2.5A).
Output current 18 A, connection of a battery not required
Output voltage 12.65V,
suitable for 12V consumers, smoothed DC voltage
