Technical data subject to change

The 9129B is an economical triple output linear

programmable DC power supply featuring

isolated outputs that can be adjusted

independently or combined in series or parallel

to output higher voltage or current. Additionally,

this supply 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 27 different instrument

settings can be saved and recalled. The power-on

state of the outputs can also be configured.

Features

■ Three independent and electrically isolated

outputs

■ Displays voltage and current settings for all

three channels simultaneously

■ Low noise, linear regulation

■ 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 27 instrument settings

■ Communicate via USB interface supporting

SCPI commands using the included USB to

TTL serial adapter

■ 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

Output Rating

Voltage

0 - 30 V (CH1 & CH2)

0 - 5 V (CH3)

Current 0-3 A (CH1, CH2 & CH3)

The USB to TTL interface supporting SCPI

commands can be used to remotely control the

power supply via a PC. Alternatively, users can

control the 9129B, 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.

This power supply is suitable for a wide range of

applications including education, service and

electronic design.
