TPRN models
A brief description of all the available TPRN sub-racks is reported hereinafter.
Passive sub-rack (TPRN04)
• TPRN04 is a passive sub-rack. It does not provide power supply to any
inserted module, and therefore it is designed to host passive modules
only. It can be useful in a multi-sub-rack system, in case the customer
decides to put all the active modules in an active sub-rack, to be chosen
among the following ones.
220 Vac powered sub-racks (TPRN14 / TPRN24)
• TPRN14 is an active sub-rack designed to be fed through 220 Vac
universal mains. Both the connector for 220Vac power supply and the
communication ports are placed on the sub-rack rear. The 220 Vac power
supply is not redundant (ie, no spare adapter is provided).
• TPRN24 is an active sub-rack designed to be fed through 220 Vac
universal mains. Both the connector for 220Vac power and the
communication ports are placed on the sub-rack rear, and the 220 Vac
power supply is redundant: i.e., a spare adapter guarantees the correct
system operations even in case the main 220Vac adapter has a
breakdown.
-48Vdc powered sub-rack (TPRN34)
• TPRN34 is an active sub-rack designed to be fed through –48 Vdc
negative supply. Both the connector for -48Vdc power supply and the
communication ports are placed on the sub-rack rear.
TPRN power supply
All the TPRN models refer to one of the following power supplies.
Universal mains
(85 to 264Vac, 50/60Hz).
This connector is mounted on the TPRN back
panel either for the redundant version or the
simple one. A ground terminal and a couple
of fuses are also included. Fuses have to be
replaced in case they fail (when it happens
the supervision system detects the failure).
