4-stage charging:
Bulk
Entered when charger is started. Constant current is applied until nominal battery v oltage is reached, depending on temperature and input
v oltage, af ter which constant power is applied up to the point where excessiv e gassing is starting (14.4V resp. 28.8V, temperature-
compensated).
Battery Safe
The applied v oltage to the battery is raised gradually until the set Absorption v oltage is reached. The Battery Saf e Mode is part of the
calculated absorption time.
Absorption
The absorption period is dependent on the bulk period. The maximum absorption time is the set Maximum Absorption time.
Float
Float v oltage is applied to keep the battery f ully charged
Storage
Af ter one day of f loat charge the output v oltage is reduced to storage lev el. This is 13,2V resp. 26,4V (f or 12V and 24V charger). This will
limit water loss to a minimum when the battery is stored f or the winter season.
Af ter an adjustable time (def ault = 7 day s) the charger will enter Repeated Absorption mode f or an adjustable time (def ault = one hour) to 'ref resh'
the battery .
