TrustedTM Power Distribution Unit 15-Way Fused-T8293
GENERAL ASSEMBLY
DESCRIPTION
The Trusted
Unit 15-way Fused provides 15
dual redundant fused power
outputs from dual redundant 24V
dc or 48V dc incoming power
feeders. The Unit is designed to
be mounted on a DIN rail.
On-board monitoring circuits
provide local LED indication of
individual fuse failure (red LED).
A common fuse failure alarm
signal is provided by the Unit via
a volt-free relay contact output.
Two 24V dc or 48V dc (link
selectable) supplies, are
distributed through 30 fuses,
arranged in two banks of 15
fuses. The outputs are fed via 15
terminal blocks labelled T1 to T7,
and T11 to T18.
TM
Power Distribution
Each supply shares a common
0V reference.
A volt-free relay contact provides
the fuse failure common alarm
signal (contact open for fuse
failure) for connection to external
alarm monitoring circuits.
FEATURES
Fifteen ‘dual’ 24V dc or 48V
dc, 3A fuse protected
outputs – suitable for direct
connection to Trusted
