The TRS/TRSN is a sub-rack unit which provides remote supply to up to 24
remote units, by means of dedicated outputs with short-circuit protection
switches.
It is available in 2 versions. The TRSN version is able to supply 1 A per port
and it can feed all remote units. The TRS version is able to supply 0.5A per
port: it can feed only single and dual band TFAN remote units, as well as the
TFAM20 one.
The TRS/TRSN unit provides DC power supply to the remote units through
standard AWG14/16 copper lines. Maximum allowed distances depend on the
section of these copper lines, on the remote unit current consumption, and on
the voltage range.
