The DP2031 is a three-output isolated linear supply that doubles as a precision current meter. Two channels give 32 V/3 A and the third gives 6 V/5 A (10 A with RIGOL's high-range option), 222 W in total, and a low current range resolves down to 1 µA so you can measure the sleep current of a battery-powered device on the same instrument that powers it.
It switches between low and high current ranges automatically, logs data and analyzes energy consumption, and offers 2- or 4-wire remote sense with front and rear terminals. A 4.3-inch color touch screen, USB, LAN, RS-232 and digital I/O, timed and arbitrary output of up to 512 points, and under 350 µVrms ripple complete it. Choose it over the DP900 when low-current measurement matters.
