Modern UPS systems use a center tap, which increases the efficiency of the entire system.
Since the two battery strings are arranged symmetrically, problems with the batteries can be recognized, among other things, by the fact
that the voltage difference in the center tap is ideally 0.0 volts.
So überwacht BACS die Strangspannung bei Mittelabgriff
While the UPS usually does not notice at this ealry point that a general problem could be present, BACS can not only determine what
caused the imbalance on the basis of the individual consideration of each individual battery, but also warn in good time before all the
batteries start charging due to incorrect charging behavior UPS can be affected:
BACS actively intervenes in the charging process and regulates each battery individually, so that the ideal condition of 0.0 volts can
almost be achieved at the center tap.
The result of this is that the drift of the voltage is not just be displayed as a general phenomon, but also the reason be spotted and
investigated by evaluation of the current data situation.
Note:
When using BACS, each battery is looked after individually and any problems are reported - since the quality of the charging current is
checked regardless of the active control and the measurement results, monitoring the string voltage in a UPS with center tap provides
additional protection:
In case of doubt, conclusions can be drawn about the general system status of the UPS itself. Since the individual results can be
evaluated by using the professional analysis software BACS Viewer, all information about UPS and for each individual battery is
available.
