Boost mode
If the battery voltage drops while power is being supplied externally because more power
is needed (e.g. because additional consumer loads are switched on), the device goes
into boost mode.
Important! To keep the battery voltage at a constant level, the charger can increase the
current to the set external supply current. In prolonged periods of high current demand,
the charger will automatically decrease the current once the maximum operating tempe-
rature is reached.
