Linear DC power supply from RIGOL provides low current measurements and improved output speed

28 September 2022

RIGOL Technologies has unveiled the DP2000 as part of its next generation of programmable linear DC power supplies. This completely new benchtop power supply features three fully isolated channels with automatic internal series and parallel connections and an intuitive 4.3 inch touch screen. The DP2000 delivers high resolution for measuring low-range currents down to 1 µA, a high-speed sampling mode, an arbitrary output mode with a 1 ms dwell time, and low output noise and ripple less than 350 µVrms.

The DP2000 will auto range between an Amps range with 1 mA resolution and the new 10 mA range with resolution down to 1 µA. These low current measurements are critical for low power devices includingSource: RIGOL TechnologiesSource: RIGOL Technologies internet of things and wearable technology.

The new DP2000 power supply complements these measurement capabilities with a high-speed arbitrary output function. This arbitrary mode is made of up to 512 arbitrary points with dwell time down to 1 millisecond and the ability to edit waveforms including sine waves, square waves, ramps, pulses or stair step functions. Users can also create their own arbitrary function to emulate the power expected in their test to diagnose power management errors and issues.

The DP2000’s three channels are rated for 32 V/3 A, 32 V/3 A and 6 V/5 A (with an option for 10 Amps on channel 3) for a total power of 222 W. The power supply has front and rear output terminals, two or four-wire remote sensing for improved accuracy, current measurement auto-ranging, and over voltage, over current and over temperature protection. Connection options include LAN, USB, RS232, GBIP (option) and digital I/O.
