multI-raIl pOwer supply unIt
A 1U multi-rail power supply unit is
used to power the analog compo-
nents in the system. These supplies
can be parallelled together. A typi-
cal system would have one of these
multi-rail power supply units, plus a
second unit acting as a “hot spare”
providing redundancy, in case the
other units fail.
Mounting
This unit should be secured into the front
of the bay by the two standard fixing
holes in each of the two 1 U front angles.
The unit should always be mounted in a
horizontal position. In many installations
the unit should be installed so that
mechanical support is provided to the rear.
Fan Cooling
The multi-rail power supply unit is fan
cooled but uses a very low noise fan,
drawing air from side to side through
the PSU instead of in from the front, to
minimise noise. Should any of the fans
slow down or stop, or any voltage rail fall
outside specified limits, a PSU Fail signal
will be sent to the console and PC to warn
the operator of a problem.

Power Monitoring & Distribution
These units are monitored via the bulk
power supply and distribution unit.
Should a fault occur, the hot spare
would automatically take over from the
primary unit, the PSU Fail Indicator on the
Broadcast Facilities panel would begin to
flash and a message would be sent to the
control surface via AWACS.
