Serial Interface Operation
voltage command
Use this command to retrieve the input voltage to the rPDU. The command response is specific to a single rPDU
and varies depending on whether the rPDU is a single-phase or three-phase model (see Table 16).
NOTE:
Voltage command query options cannot be used for single-phase rPDUs. However, query options can be used
with voltage command for three-phase rPDUs.

Description
XN
RMS voltage between X and N
L1 Line to Neutral on a Wye-configured rPDU
YN
RMS voltage between Y and N
L2 Line to Neutral on a Wye-configured rPDU
ZN
RMS voltage between Z and N
L3 Line to Neutral on a Wye-configured rPDU
XZ
RMS voltage between X and Z
L1 Phase to Phase on a Delta-configured rPDU
XY
RMS voltage between X and Y
L2 Phase to Phase on a Delta-configured rPDU
YZ
RMS voltage between Y and Z
L3 Phase to Phase on a Delta-configured rPDU
1
Line-to-Neutral voltage will not be reported on a Delta-configured rPDU
2
Line-to-Line voltage will not be reported on a Wye-configured rPDU
Usage
rPDU>voltage [summary] [XN|YN|ZN|XZ|XY|YZ]]
where:
[summary] = Retrieves a summary of voltage per phase for all three phases
[XN|YN|ZN|XZ|XY|YZ] = Phase line (see Table 16)
Retrieve the present input voltage for rPDU phase lines
rPDU> voltage
