2. Technical description.

2.1. General description.

19" DSO-PRA RACK cabinet is designed for installation of PRAESENSA voice alarm system devices by

Bosch.

Devices of DSO system are placed in 19" RACK cabinet together with appropriate battery banks.

Power supply from power grid can be supplied to cabinet in form of 1-phase or 3-phase connection, which

depends on total power consumed by DSOdevices.

CONFI DSO PRAESENSA program is designed for proper and fast configuration of DSO cabinet; based on

implemented design parameters, program selects a complete power supply system taking into account required
backup time.

2.2. Electrical scheme.

Figure 1 shows an exemplary wiring diagram inside a DSO cabinet for a 3-phase 230 V / 400 V AC

connection.

PRA-MPS3

– multi-functional power supply

PRA-SCL

– system driver
