The input supply range for the PIDU Plus is 90V-264V AC, 47-63Hz. Mains connection
to the PIDU Plus is made using a standard “figure of eight” mains lead as shown in
Figure 6.

Redundancy and alternative powering configurations
The PTP 600 Series can be powered from an external DC source and can be provided
with power supply redundancy as follows:
• External DC supply only (Figure 1-8): This config
uration is for use where there is
no mains supply.
• External DC supply and AC supply (Figure 1-9): Thi
s configuration provides
redundancy through the use of mains and DC supply.
• External DC supply and redundant AC Supply (Figure 1-10): Th
is configuration
guards against mains failure and failure of the DC output of single PTP
300/500/600 PIDU Plus.
NOTE
The use of DC supplies of less than 55v will reduce the usable distance
between the PIDU Plus and ODU (Figure 1-7).
