Keysight U8030 Series

Triple-Output DC Power Supplies

Data Sheet

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.

Introduction

Unrivalled performance—

with low output noise and

excellent load regulation

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).

Added safety features—

with OVP, OCP and

physical lock mechanism

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.

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 but-

ton allows multiple outputs to be con-

trolled 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.
