Applications
In this overview the three main applications are shown with their options.
Technical Informations
The DBM20A provides a
3 to 4 step charging
programm
:
1. Step:
Bulk
The Bulk step is the first step of
charging. In this step the battery is
charged with a constant maximal charge
current until chosen charge voltage is
reached.
2. Step:
Absorption
As soon as the chosen voltage is
reached on the battery, the next step
starts. While the absorption the most energy is charged into the battery. Here the charging
current gets lower and lower while keeping the voltage constantly on chosen level.
3. Step:
Optional
Equalize
After current drops under 3 amps the optional equalize starts (only when configured and
only once in a month at most). In this step the charger boosts the voltage for an additional
0.6V on the battery for a certain period. This forces the sulphation to be reversed which
helps the battery to last longer and in a better state (
CAUTION
: not all the battery types are
made for this step or need it. Instructions and specifications provided by the battery
manufacturer must be considered!)
4. Step:
Float
As the current drops below 3 amps in the absorption step, respectively equalize is finished,
the float step starts. As the charge procedure is finished at this point the charge voltage is
reduced to 13.7V to counterbalance the self-discharge of the battery without overcharging
it.
