PTX10003 AC/HVDC Power Supply Description | 50

PTX10003 DC Power Supply Description | 59
The PTX10003 is powered by 3000-W redundant AC/HDVC or DC power supplies that are pre-installed
at the factory. The PTX10003-160C is powered by four power supplies for 2+2 redundancy. The
PTX10003-80C is powered by two power supplies for 1 + 1 redundancy. The power supplies are
hot-removable and hot-insertable. If one power supply fails, you can replace it without powering off or
disrupting the routing function. The other power supply balances the electrical load without interruption.
Each power supply has two outputs: 12 V and 12 V standby. Two counter-rotating fans in each power
supply provide front to back cooling. The input voltages are as follows:
AC input voltage range: 200—277 V/50—60 Hz
DC input voltage range: —40 VDC Min, —72 VDC maximum
CAUTION:
PTX10003 AC/HVDC Power Supply Description
The input power to the AC/HVDC power supplies can be AC power or HVDC power. The power supplies
automatically detect whether there is AC or HVDC input voltage and manage the power accordingly. AC
power can be 180—305 VAC input voltage and HVDC power can be 190—400 VDC input voltage. Each
3000- W AC/HVDC power supply module has a single AC or HVDC input and provides 12 V power to
the system.
Figure 16 on page 51 shows the location of the AC/HVDC power supplies on the PTX10003-160C FRU
panel, and Figure 17 on page 51
FRU panel.
Do not mix AC/HVDC and DC power supplies in the same chassis.
