More Protection, More Convenience — For Less
It’s often difficult to find a power supply that is just right for your test
requirements and your budget. Whether you’re manufacturing consumer
products, testing electronic components, or simply looking for reliable, affordable
power, Agilent’s family of basic power supplies now includes single output,
non-programmable models in the 90 W to 150 W power range. With capabilities
typically found only in programmable supplies, you get excellent value along
with great efficiency in your work. As a result, you can minimize setup time and
measurement errors and maximize device reliability. You’ll get the right power
with a difference — backed by stringent safety certifications and Agilent quality
standards — at an affordable price.
The Agilent U8000 Series offers 90 W to 150 W single output, non-programmable
DC power supplies that include features typically found only in costly
programmable supplies. The U8000 Series delivers excellent value by providing
reliable DC power, efficient setup capabilities, and important security features
that let you address a variety of applications in electronics manufacturing and
educational settings.
Power That’s Suitable for Your Application
The U8000 Series with power ranging from 90 W to 150 W provides performance
that is suitable for electronics manufacturing for computers and peripherals,
communication systems and peripherals, aircraft/avionics systems, electronic
components, and more. The U8000 Series complements the Agilent E3600 DC
power supplies family to provide a wider range of power source alternatives.
Work Efficiently with
Great Features and
Solid Performance —
Within Budget
Differentiated features typically found
only in programmable power supplies
The U8000 Series offers fully
integrated over voltage protection
(OVP) and over current protection
(OCP) to prevent damage to the
device-under-test (DUT). Using the
capability to save and recall three
memory states, you can minimize
errors and reduce set-up time. The
U8000 Series also provides security
features such as keypad lock to
prevent measurement errors due
to accidental front panel usage.
When the keypad lock is activated,
the knob and all the buttons on the
front panel are disabled except the
keypad lock button. The physical lock
mechanism found at the rear panel
of the power supply provides secure
instrument storage. The LCD display
with backlight on/off options enables
brighter display for data viewing (see
Figure 2).
Get That Something
Extra: Safety and
The U8000 Series has been stringently
tested according to various industrial
safety standards: CSA (for US and
CA regulatory requirements), C-tick
(Australia), and CE (Europe). The
U8000 Series is fully integrated with
OVP and OCP in order to prevent
damage to the DUT. The security
features offered in the U8000 Series
prevent measurement errors and also
ensure safety storage of the power
supply. Security features such as
keypad locking capability preclude
accidental front panel usage while
the physical lock mechanism provides
secure instrument storage.
Front Panel Operation
An easy-to-use rotary knob and
self-guiding keypads allow you to set
the output at your desired resolution
without any effort. Also, both voltage
and current levels can be set to a
maximum resolution of 10 mV/10 mA
from the front panel. In addition, you
can save and recall for up to three
operating states that are stored in the
internal non-volatile memory.
Easy-to-use control functions:
• Enabling or disabling OVP and
• Setting the OVP and OCP trip
• Clearing OVP and OCP conditions
• Setting and displaying the voltage
and current limit values
• Operating state storage/recall
• Resetting the power supply to
power-on state
• Calibrating the power supply
• Enabling or disabling the output

Solid, reliable performance in its
The U8000 Series provides excellent
load and line regulation (Constant
Voltage, CV: < 0.01% +2 mV; Constant
Current, CC: < 0.02% +2 mA) to
ensure stable output even when the
load changes. With the fast 50 µsec
transient response, test times and
manufacturing cost are significantly
reduced. The U8000 Series comes with
low output noise of 1 mVrms, 3 mArms
from 20 Hz to 20 MHz, providing clean
output and minimizing the interference
in the DUT.
