Power POD main features
• hosts the portion of power system able to distribute the power coming from the JB to the
users.
• The users are: 14 floors, and all the local electrical loads located in the Base Power Pod
(BPP), Base Electronic POD (BEP) and base Optical POD (BOP), external
instrumentation included.
• All the distribution lines are remotely switchable except for the local line that feeds the
control system.
• The communication between the local control system and shore is realized through a
FCM board (located in the BEP) via optical fibres.
• The Power Supply System (PSS) board e the Power Control System (PCS) board are
located in the PP.
• The PSS allows voltage conversion from 375 V, delivered by the JB, to low voltages
required by all the electrical loads.
• The PCS allows monitoring and control of: V at the input and I of all the distribution lines,
T and remote switch actuation.
• In case of communication loss between PCS and FCM, the PCS guarantees the output
lines feeding, thanks to a time-out system that automatically actuate all the switches of
these lines.
• The BPP will be oil filled, all the electronics components present inside it withstand oil
bath.

PSS - Power Supply System Board features
The Power supply Board converts the 375V to a series of low
voltages required by the users, its main features are listed below:
• Working environment: oil bath,
• Protection against input transient overvoltage,
• 12V, 5V, 3.3V, 1.8V, 1.2V output voltages,
• Soft start outputs (3.3V, 1.8V, 1.2V),
• Flexible start up output sequencing,
• 375 V input line current and voltage monitoring,
• 5V output line current monitoring,
• 50 W maximum total outputs (included DC/DC conversion
losses),
• Low output voltage ripple,
• 12V isolated power supply for oceanographic instrumentation.

PCS - Power Control System
features
• Working environment: oil bath,
• Working voltage 375V DC, max power 5 kW,
• Distribute power to up to16 output lines,
• Monitoring of input voltage and current of all output lines,
• Monitoring of ambient parameters: temperature,
• Remotely operated switches in all the output lines with a soft start system
(100ms controlled voltage ramp),
• Communication
interface
between
PCS
and
the
system
via
isolated
asynchronous serial RS232,
• Output short circuit protection. In case of an output line fuse blow up, the 375
V return will be opened to completely isolate the output load affected by the fault,
• Time-out system that automatically actuate all the switches of the output lines
in case of communication loss between PCS and the system,
• Output lines current threshold remotely settable,
• Autonomous switch off for over current threshold.
