Required minimum voltage of the battery - this
defines the voltage limit which must be
exceeded by the battery before starting to
charge [1].

The lower limit is dynamic and depends on the
configured values I
tri
and I
re
.
The possible maximum to reach depends on the
power class of the device (see data sheet). [2]
ATTENTION: The current limit has to be
checked and if necessary adapted to the
connected equipment (e.g. charging cable and
clamps)
I

[1 ... 20] A; Limiting value from which the DBL
switches to trickle charge.
I

Recharge current
[0.5 … 30] A; Threshold (Delta-Value) above I
tri
,
from which on the DBL switches back to
CHARGEMODE.
