PTX10003 DC Power Redundancy

To provide power redundancy for the PTX10003, the power supply modules must be connected to an
80 A power source and the input current selector (DIP switch) on the power supply must be set to 80 A.
For the PTX10003-80C, the maximum power budget is 3000 W. For the PTX10003-160C, the maximum
output power budget is 4700 W.
CAUTION:
The PTX10003 DC power supply does not support an 60 A power source in Junos OS Evolved software
release 19.1. When installing the PTX10003 DC power supply, be sure you set the input current selector
to 80 A.

PTX10003 Input DC Voltage Specification

The PTX10003 DC power supply modules operate within the DC input voltage range listed in
Table 20 on page 64.
NOTE: Depending on the available input source, Juniper recommends that the 48-VDC facility DC
source be equipped with a circuit breaker rated at a minimum of 60 A (-48 VDC) or 80 A (-48 VDC),
or as required by local code.
Then...
The power supply limits the output power to 2200 W at 40 V input and linearly
increases the output power if the input voltage increases. The power supply provides
3000 W output power for input voltage greater than 55 V assuming 92% efficiency.
CAUTION: The PTX10003 DC power supply does not support a 60 A power source
in Junos OS Evolved software release 19.1. When installing the PTX10003 DC power
supply, be sure you set the DC input current selector (DIP switch) to 80 A.
The power supply provides 3000 W output power throughout the input voltage range
from 40 VDC to 72 VDC.
