Fig. 9 Example of the charge voltage behaviour with the LAS 1218-2 battery charger
I Main charge with maximum 18 A charging current, electronically limi-
ted, up to final charging voltage. Start of charge also for totally discharged batteries.
Uo Automatic changeover to full charge with constant 14.3 V. The duration
of the full charge phase depends on the type of battery and is configured on the device: Lead-acid batteries, 4 hour, lead-gel batteries, 16
hours.
U Automatic changeover to trickle charge with constant 13.8V. In the
trickle charge phase, the voltage at the output of the charging module
is constant. The battery is now fully, or virtually fully, charged.
Start of a new charging cycle by switching over to main charge, if the battery
voltage falls below 13.8 V for more than 5 seconds when loaded. Start of
charge also for totally discharged batteries.
For mains operation, the starter battery is also charged (with maximum
charge current of 3A). The final charge voltage is 14.1 V.
Output current 18 A, connection of a battery not required
Output voltage 14.3V/13.8V,
suitable for 12V consumers, smoothed DC voltage
