Main Supply
9.3.1
32" Sets
The 32" sets in this chassis can come with a buy-in supply
unit:PLCD170PS09B.
When defective, a new panel must be ordered and the
defective panel must be sent for repair, unless the main fuse of
the panel is broken. Always replace a defective fuse with one
with the correct specifications! This part is available in the
regular market.
Refer to the Spare Parts list for the order number of the supply
unit.
PLCD170PS09B
The supply unit delivers the following voltages to the chassis:
•
24 V
inv

DC output protections - Short Circuit Protection
The 3.3 V standby power circuit has short circuit protection with
an auto restart function and an over voltage protection which
operates within a range of 120 to 140% of the nominal value.
In case a short-circuit situation occurs at the 12 V, 12 V
B
or
24 V
A
output the over voltage protection operates within a
range of 120 to 140% of the nominal value.
In case a short-circuit situation occurs at one of the + 12 V
A
or
- 12 V
A
outputs, the over voltage protection intervenes at a
maximum value of 19 V.
In case a short-circuit situation occurs at the 24 V
INV
output, the
supply unit will auto-recover when the fault condition is
removed. It operates within a range of 120 to 140% of the
nominal value.
