Couple of years back I needed a lab power supply and I bought one, which supports computer control. RND Lab 320-KA3005P is the model. Nothing fancy, but does its job. It came with software for computer control. I immediately recognized LabVIEW controls and looked for LabVIEW driver, but couldn’t find one. I decided to write one myself. The instructions manual was not bad and provided most of the commands. For some I had to search for manual of other similar power supplies. It turned out that there are multiple companies, which use the same commands (perhaps same firmware and maybe even same hardware made in the same factory).
