The full story
psu-top is a terminal tool, built by Claude Code, that monitors and controls SCPI bench power supplies in the style of htop. Its maker wanted to watch current draw remotely while working on low-power hardware.
It was written for and tested on the Kiprim DC310S, a rebranded OWON SPE3103, over USB serial. Rolling strip charts autoscale so small currents stay visible, and keys set voltage and current or toggle the output, with values clamped to 0-30 V and 0-10 A.
It finds the supply by sending an identification query to every serial port, so the README advises naming the port when other instruments share the bench. It is on pip under the MIT licence.
