NOTE
If a battery sensor (accessory) is connected, the device adjusts the
voltage according to the measured values.
For this purpose the battery sensor has to be configured with DSP-EM.
The battery is charging with IU0U characteristics (fig. g).
1: I phase (bulk)
At the beginning of the charging process, the flat battery is charged with a constant
current (100 % charge current) until the battery voltage reaches the charging end
voltage. The charging current decreases when the battery has reached this charging
level.
2: U0 phase (absorption)
Now the two-stage absorption charging process (U0-Phase) begins, where the
charge voltage and duration depend on the size and type of the battery. The voltage
remains constant until the minimum charging current (6 % of the set current) or the
maximum charging time (10 hours) is reached.
3: U Phase (floating)
The U phase serves to maintain the battery capacity (100 %).
If DC loads are connected, they are powered by the device. Only if the power
required exceeds the capacity of the device is this surplus power provided by the
battery. The battery is then discharged until the device re-enters the I phase and
charges the battery.
