The DP900 is a three-output linear supply with all three channels electrically isolated from each other, which makes floating, stacked and ground-referenced rails simple to set up. Two channels give 32 V/3 A and the third 6 V/3 A, up to 210 W total (DP932E: 30 V/3 A, 198 W), and CH1/CH2 can be combined in series or parallel internally.

A 4.3-inch color touch screen, USB, LAN and digital I/O, timed and arbitrary output (up to 512 points), data logging, and under 350 µVrms of ripple make it a modern replacement for older three-output supplies. The DP932U adds front-panel safety sockets for classrooms; the DP932E is the value version.
