Technical data subject to change

The 9130B Series triple output linear

programmable DC power supplies feature isolated

outputs that can be adjusted independently or

combined in series or parallel to output higher

voltage or current. Additionally, these supplies

can operate in tracking mode with

user-configurable ratios between channels.

The front panel keys and rotary knob with

convenient cursors let users quickly set voltage

and current values. Up to 36 different instrument

settings can be saved and recalled. The power-on

state of the outputs can also be configured.

For remote control, the standard USB (USBTMC-

compliant), RS232, and GPIB interfaces

Features

■Three independent and electrically isolated

outputs

■Displays voltage and current settings for all

three channels simultaneously

■Low noise, linear regulation

■High programming and readback resolution of

1 mV / 1 mA

■Series and parallel modes combine channels to

increase the output voltage or current

■Tracking mode allows users to set up channels

to maintain a programmed ratio

■Fully programmable channels with Output

On/Off control

■Store and recall up to 36 instrument settings

■Remote sense

■Timer-controlled output function adjustable

from 0.1 – 99999.9 s

■Standard USB (USBTMC-compliant), RS232,

and GPIB interfaces supporting SCPI

commands for remote control

■NI certified LabVIEW driver and softpanel for

remote control, test sequence generation, and

datalogging available

■Overvoltage (OVP) and overtemperature (OTP)

protection including keylock function

■Compact 19” half-rack form factor allows for

side-by-side rack mounting of two units

supporting SCPI commands can be used to

remotely control the power supplies via a PC.

Alternatively, users can control the power supply,

execute test sequences or log measurements

using the provided PC software application. This

software also integrates with Data Dashboard for

LabVIEW apps enabling iOS, Android, or

Windows 8 compatible tablets or smartphones to

remotely monitor select measurement indicators.

These power supplies are suitable for a wide

range of applications including production

testing, telecommunications, R&D, electronic

service, and labs.

9130B Series

Flexible operation

Combined series mode

Channels 1 and 2 can be wired in series to

increase the voltage. Selecting Series Combined

Mode provides convenient metering of the

channels connected in series.

Test system integration

These power supplies offer standard USB, RS-232, and GPIB interfaces to facilitate test system

development and integration. The 9130B Series supports SCPI-compliant protocols and come with

LabVIEW™ drivers.

Application software

PC software is provided for front panel emulation, generating and executing test sequences or logging

measurement data without the need to write source code.

■ Remote monitoring on iOS, Android, or Windows 8 compatible tablets or smartphones via NI Data

Dashboard for LabVIEW apps.

■ Log voltage, current, and power values of each channel as well as timestamp, CV/CC mode, and output

status.

■ Quickly develop a custom dashboard with indicators, charts, or gauges to monitor your power supply.

■ Create an unlimited number of external list files to be executed from PC memory. Save and recall list

files to/from the PC.

Channels 1 and 2, 2 and 3, or All channels can

be wired in parallel to increase the current.

Selecting Parallel Combined Mode provides

convenient metering of the channels connected

in parallel.

Tracking mode

Tracking mode can be used to simplify

adjustments across multiple channels by

maintaining a user-defined ratio between outputs.

Tracking mode can be set on channels 1 and 2, 2

and 3, or All channels.
