The BK Precision 9129B Programmable Triple-Output DC Power Supply, (2)30V/3A, (1)5V/3A, 120VAC Line Input features isolated outputs that can be adjusted independently or combined in series or parallel to output higher voltage or current. 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 can save and recall up to 27 different instrument settings, and 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 9129B via a PC. Alternatively, the 9129B can be controlled, execute test sequences or log measurements using the provided PC software application.
