3.2.1.3 GNSS splitter
The GNSS splitter (Global Navigation Satellite System) is used for connecting the GNSS
antenna and the allocation and distribution of the received GNSS signal (e.g. GPS, Gal-
ileo or Glonass) to up to two BSCUs. The GNSS splitter is installed in the connection and
control panel.
3.2.2 V
AC
power supply
DIB-R5 flexibleTx can be operated with an input voltage of 90 V
AC
to 250 V
AC
.
The V
AC
power supply consists of the following components:
n
AC Power Distribution Module (APDM)
n
Power Supply Unit (PSU) including Power Supply Module (PSM)
3.2.2.1 AC Power Distribution Module (APDM)
The AC Power Distribution Module (APDM) is used for connecting the power supply and
the power distribution to the backplane and the installed hardware components. The
APDM is used for the V
AC
power supply. The V
AC
input voltage is fed via the Power
Supply Unit (PSU), converted to the required operating voltage, and subsequently distrib-
uted to the backplane and the installed hardware components.
With redundant power supply line, two APDMs are installed (optional). The redundancy
options of the power supply are described in
.
The following figure shows the top view of the APDM. The following table describes it in
detail.
