Products with 3-Phase Inputs
Some of the higher power products
exceed the capability of a single
phase line. Agilent offers several
power products which require
3-phase inputs, including the
5kW 668XA and 6.6 kW 669XA
dc source family. For 3-phase
power distribution up to the
building, there are two different
distribution systems in wide use:
delta, predominantly used in the
US; and wye predominantly used
in Europe. However, for service
inside the building, the 5 wire wye
is the predominant configuration.
Products which are delta loads,
are compatible with either delta
or wye.
As shown in table 4, the delta has
only three current carrying con-
ductors; there is no neutral. The
wye configuration has four current
carrying conductors. In general,
the neutral should carry no signifi-
cant current. None of the Agilent
power products use the neutral
connection found on wye systems.
Do not connect the neutral to
ground.
In selecting the correct operating
voltage for 3-phase products you
need to distinguish between the
line-to-line and the line-to-neutral
voltages. The line-to-line voltage is
the square root of 3 x the line-to-
neutral voltage. It is the line-to-line
voltage that is used to specify the
input voltage to be applied to
Agilent power products. For exam-
ple, common 3-phase voltages and
available options are shown in
table 4.
