Linear DC power supply provides low current measurements

RIGOL Technologies has released its next generation of Programmable Linear DC Power Supplies, the DP2000. This new benchtop power supply features three fully isolated channels with automatic internal series, parallel connections, and an intuitive 4.3" touch screen. The device provides high resolution for measuring low-range currents down to 1µA, a high-speed sampling mode, an arbitrary output mode with a 1ms dwell time, and low output noise and ripple <350µVrms.

The device will auto range between an amps range with 1mA resolution and the new 10mA range with resolution down to 1µA. These low current measurements are crucial for low-power devices, including IoT and wearable technology.

This new power supply complements these measurement abilities with a high-speed arbitrary output function. This arbitrary mode comprises up to 512 arbitrary points with dwell time down to 1 millisecond and the capability to edit waveforms, including sine waves, square waves, pulses, ramps, 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 represents RIGOL's next generation of Linear Power Supplies and moves us into a wide range of new and exciting application spaces, including low power IoT devices and wearables, automotive, manufacturing and ATE testing," stated Chris Armstrong, director of Product Marketing for RIGOL USA. "We anticipate the feature set and price point of the DP2000 will compare very favourably with the market-leading power supplies while delivering exceptional accuracy and resolution."

The device's three channels are rated for 32V/3A, 32V/3A and 6V/5A (with an option for 10A on channel 3) for a total power of 222W. 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 incorporate LAN, USB, RS232, GBIP (option) and digital I/O.
