The DVS-21 slide-in module SV01-PL is part of the ProCom SOS Line concept.
Whenever the 48V DC supply voltage for feeding the SOS line is not sufficient due to cable
length, the SV01-PL module is applied. It converts the nominal supply voltage of 48V DC of
the DVS-21 system into either 48V DC or 60V DC or 72V DC and forwards it towards a NSA-
PL module. At the same time, output and input voltage are isolated galvanically. Thus, it for-
wards a transformed supply voltage towards the WPS-PL call stations. Moreover, it provides
continuous short-circuit protection for the NSA-PL module connected.
The output voltage is set up in using the configuration software ICS.
For monitoring both output voltage and output current of the SV01-PL are measured and the
reading is passed to the processor module. There, as option, it can be evaluated. The vari-
ous operational statuses are displayed on the front plate LEDs.
