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 maintain the battery voltage at a constant level, the charger can increase
the current in boost mode to the maximum charging current (see Technical Data).
To prevent the device overheating, the max. output current can be automatically limited if
the ambient temperature rises to above 35°C/95°F (power derating).
