Picture 5 – 1200 kVA UPSaver, "CB+DSB" configuration
In the "CB+DSB" configuration the battery bank is single for the whole UPSaver system, and
is connected to the I/O module common DC bus. Each power module is connected to the DC
bus via the isolators BCBx, located in the I/O module side distribution columns. Each module
proportionally contributes to the battery charge, which is charged in parallel by all the modules,
providing a fraction of the current. The battery static switch is installed inside the I/O module.
The bypass static switch is distributed, therefore it is provided in each power module. The
pus-buttons SBCBx, which allows the operation of the back-feed contactor and the supply of the
power modules bypass line, are installed in the distribution columns.
