BK Precision 9129B – Triple Output Programmable DC Power Supply
Displays voltage and current settings for all three channels simultaneously
Three independent and electrically isolated outputs
Low noise, linear regulation
Fully programmable channels with output On/Off control
Store and recall up to 27 instrument settings
The BK 9129B is a fully Programmable Triple Output DC Power Supply delivering 0-30V/ 0-3A on channels 1 and 2 and 0-5V/0-3A on channel 3. Each output can be adjusted independently and they can be connected (CH1 and CH2) in series or parallel to produce higher voltages or currents. The front panel keys and the encoder knob provide efficient options to adjust the voltage and current of any of the three outputs, enable or disable parallel, series or tracking mode, store and recall operating states and enable/disable individual outputs.

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.

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.
Combined parallel mode
Channels 1 and 2 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.
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.
Bipolar output configuration
The independent and isolated outputs can be used to create positive and negative outputs between channels 1 and 2.

This feature is useful for powering bipolar circuits and devices.
