OWON SPE3103 software
Remote control and data logging for the OWON SPE3103 power supply, on Windows, Linux and macOS - with the same panel BenchMesh uses for every power supply.
Awaiting confirmation
Status
Very likely. Support for the OWON SPE3103 was written from OWON’s programming manual and follows the same engine as the bench-tested instruments, but nobody has confirmed it on a real SPE3103 yet. If you own one, connecting it once and reporting the result moves it to Community-confirmed.

Have one on your bench?
Connect it, press Detect, try the controls - then tell us how it went. Every confirmation moves a model from “Awaiting” to “Community-confirmed” for everyone.
Questions
- Does BenchMesh work with the OWON SPE3103?
- Very likely. Support for the OWON SPE3103 was written from OWON’s programming manual and follows the same engine as the bench-tested instruments, but nobody has confirmed it on a real SPE3103 yet. If you own one, connecting it once and reporting the result moves it to Community-confirmed.
- How do I connect the SPE3103 to my PC?
- Over USB-serial / RS-232. 115200 baud, 8N1. Plug in the USB cable (or a USB-RS-232 adapter); BenchMesh finds the port. Then press Detect in BenchMesh: it identifies the power supply by its reply and adds it to the bench.
- What can I control on the SPE3103?
- Power supply: set current, current limit, output, remote, voltage, voltage limit; read cc, cv, fail, iout, ocp, otp, output, ovp.
- Can I log SPE3103 measurements to CSV?
- Yes. Right-click any reading to add it to a recording; every instrument on the bench is sampled on one shared timeline and exported as one CSV.
- Is BenchMesh free?
- Yes. BenchMesh is free and open source, for Windows, Linux and macOS, and works offline.
