Family of affordable, autoranging
system DC power supplies
The Agilent Technologies N8900
Series provides 5, 10, and 15 kW
autoranging, single-output program-
mable DC power for ATE applications
that require just the right amount of
performance at just the right price.
The N8900 Series power supplies’
autoranging output characteristic
enables unprecedented flexibility by
offering a wide range of voltage and
current combinations at full power.
Power supplies with “rectangular,”
or traditional, output characteris-
tics provide full power at only one
voltage and current combination.
Just one N8900 does the job of
multiple power supplies. It’s like
having many power supplies in one!
The N8900 Series provides stable
output power, built-in voltage
and current measurements, and
autoranging output voltage and
current from 80 to 1500 V and 10
to 510 A. These supplies offer many
system-ready features like multiple
standard I/O interfaces to simplify
and accelerate test-system develop-
ment and compact 3U design to
save rack space.
