Triple Output Programmable DC Power Supply

Model 9129B

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.

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.
