3.3. Battery selection
The charge algorithm of the charger must fit the battery type connected to the charger. The following table shows all the
predefined battery types available in the charge algorithm selection menu.

3.4. Power supply mode
The charger can be set to operate as a DC power supply.
In this mode, the charger functions as a constant voltage source:
1. an adjustable output voltage of 8.0 to 15.9 V (12 V type) resp. 16.0 to 31.8 Volt (24 V type)
2. a maximum output current of 60A (12 V type) resp. 30A (24 V type).
3.5. Temperature compensation (dV/dT)
The temperature sensor should be connected to the plus or negative pole of the battery.
The temperature compensation is a fixed setting, see table and fig 7, and applies to all charge states.
The temperature sensor must be installed when:
- ambient temperature of the battery is expected to regularly be lower than 15 °C or to regularly exceed 30 °C
- charge current exceeds 15 A per 100 Ah battery capacity
Temperature compensation is not required for Li-Ion batteries.
3.6. Power Control – maximum use of limited shore current
A maximum mains current can be set in order to avoid interruption of an external fuse in the mains supply.
