Principle of Operation of the SBS, Electrical
If the SBS is supplied by connecting the mains or the load voltage,
the corresponding operating status is automatically activated after
3 to 5 seconds.
the corresponding operating status is automatically activated after
3 to 5 seconds.
With mains operation, the DOU displays load voltage and SBS
current. With all other operating statuses, in addition to the load
voltage the corresponding status (ready, blocked, fault) is displayed.

The toggle switch on the DOU serves exclusively to acknowledge
SBS faults.
SBS faults.
The SBS control unit continually monitors the load voltage and, in the
event of a load voltage deviation, initiates switchover of the loads
from the INV/INVs to the SBS without interruption. Then the loads are
automatically switched back to the INV/INVs. The thyristors of the
SBS only quench when the supply of the loads is guaranteed by the
activation of the output contactors of the INV/INVs.

When the SBS is fired, both antiparallel thyristors are triggered over
the whole period ensuring reliable operation of the SBS in the entire
range from inductive to capacitive load.

range from inductive to capacitive load.
The entire control and monitoring process is carried out using a
microprocessor. LEDs and relays show the unit status, whilst the
output voltage and output current are displayed on an LCD. If the
SBS is operated with one or more INVs connected in parallel, a CAN
bus is required between the units for control purposes. An additional
CAN bus allows the unit to be integrated in a power supply system
and connected to a central control and monitoring unit (PSM).
