Keysight U8030 Series
Triple-Output DC Power Supplies

Data Sheet

Introduction
Higher Power. Better Reliability. Unrivalled Performance.
Keysight Technologies, Inc. extends its family of basic DC power supplies to include a one of a kind power
supply that offers up to 375 W power at three outputs. Equipped with output sequencing capability, it allows
you to generate output sequences even with minimal programming skills. Each power supply is also built
with excellent load regulation and clean output noise for continued stability. With these and many other
features, you get a solid and reliable triple-output power supply at an unsurpassed performance.
The U8030 series offers two models — the U8031A and U8032A, each with different voltage and current
ratings to cater to your needs. Both models are well-regulated compact bench-tops with total output of
375 W, making it an ideal power source alternative in electronics manufacturing, research and development
as well as education sector.

Generate power supply output sequences —
No extensive programming skills necessary
The output sequencing capability is carefully thought out for your convenience and ease when operating.
Designed to perform automation function, our U8030 series is well-suited even for those with minimal
programming skills. With easy-to-use knob and intuitive keypads, you can now set your desired output
sequences for margin test, burn-in test and other general purpose tasks in an industrial setting.

Key Features
–– Provides total power of 375 W for three outputs
–– Output sequencing capability
–– Excellent load and line regulation (CV: < 0.01% + 2 mV; CC: < 0.02% + 2 mA) ensures stable output
–– Provides clean output with ≤ 1 mVrms (0.5 mVrms typical) noise
–– Fast < 50 µs transient response for stable testing
–– Dual display shows both voltage and current reading
–– Over-voltage and over-current protection
–– Security features: keypad lock and physical lock mechanism

Unrivalled performance— with
low output noise and excellent
load regulation

Added safety features—
with OVP, OCP and
physical lock mechanism

The U8030 series provides excellent
load and line regulation (CV: < 0.01%
+ 2 mV; CC: < 0.02% + 2 mA) to
ensure stable output even when load
changes. This is crucial especially
when dealing with noise-sensitive
circuits that demand clean power. At
a wide bandwidth of 20 Hz to 20 MHz,
our bench power supplies continue
to provide clean output at the lowest
Vrms ≤ 1 mVrms (0.5 mVrms typical),
leaving your signals uncontaminated
and ensuring minimal interference to
your Device-Under-Test (DUT).

Safety is an important consideration
when dealing with power. Users may
not only want to protect themselves
from exposure to current, but also
the additional costs incurred to their
investment (DUT). Our U8030 series
power supplies are integrated with
an array of security features such as
over-voltage (OVP) and over-current
(OCP) protection to mitigate these
risks.

intuitive keypads

Figure 2. Backlight on/off feature with dual reading
(voltage and current) on an LCD display

Additionally, security features such
as keypad locking capability prevents
accidental front panel usage while
physical lock mechanism which is strategically located at the rear of the unit
provides secure instrument storage.

Differentiated features—
allowing you to work better
Both models of the U8030 series
come with a set of features to suit
your needs while remaining easy to
use. The LCD screen displays both
voltage and current readings in a
one-view panel while the all ON/
OFF button allows multiple outputs
to be controlled simultaneously.
Additionally, the auto-track feature
simplifies setup between output 1
and output 2. With these, you get
a solid bench power supply plus a
set of convenient and easy to use
features.
