5. The PS24DSOxxxx power supply unit.
The PS24DSOxxxx power supply is the main component of the DSO power supply system supplying power
to the controller and routers of the DSO system during normal operation (mains supply operation) and performs
advanced battery charger functions.
Due to its modularity, the power supply can be configured in one of several possible variants, differing in
power, the number of outputs for audio amplifiers, and the number of battery strings. Depending on the design
requirements the power supply can have a power of 320 - 1000W and work with batteries with a capacity of up to
460Ah.
In addition, each power supply unit is equipped with an additional Ethernet module with a 10Base-
T/100Base-TX interface to connect to the Internet. Such a configuration enables the remote monitoring of the Voice
Alarm System over the Internet from anywhere.
Choosing the right power supply configuration taking into account all the requirements is done
automatically using the "CONFI-DSO" support program.
5.1. Block diagram.
The power supply unit is based on the high performance AC / DC inverter with an integrated power factor
correction PFC. The used microprocessor system is responsible for the complete diagnostics of parameters of the
PSU and batteries. The figure below shows a block diagram of the power supply along with the selected functional
blocks. The power supply unit is additionally equipped with the Ethernet communication module allowing remote
monitoring of system parameters.
