Precision Measurement, Low Noise, Programmable.
The 2280S-32-6 and 2280S-60-3 Precision Measurement, Low Noise, Programmable DC Power Supplies are much more than just sources of clean power; they are also precision measurement instruments. They can source stable, low noise voltages as well as monitor load currents over a wide dynamic range from amps to nanoamps. The Model 2280S-32-6 can output up to 32 V at up to 6 A; the Model 2280S-60-3 can output up to 60 V at up to 3.2 A.
DMM-Quality Low Current Measurements with High Resolution
Unlike conventional power supplies, these Series 2280S supplies can also make measurements with up to 6-1/2 digits of resolution. Voltage output measurements can be resolved down to 100 μV. These supplies measure load currents from 100 nA to amps and can resolve down to 10 nA. Four load current measurement ranges (10 A, 1 A, 100 mA, and 10 mA) support measuring a device's full load current, standby mode current, and small sleep mode currents with DMM-quality accuracy. The high resolution allows characterizing small changes in load currents with confidence. It also makes it possible to make a broad range of measurements on a single range with excellent accuracy across both low and high current values.

Both supplies use linear regulation to ensure low output noise and superior load current measurement sensitivity. A high resolution color Thin Film Transistor (TFT) screen displays an icon-based main menu and a wide range of information on measurements. Soft-key buttons and a navigation wheel combine with the TFT display to provide an easy-to-navigate user interface that speeds instrument setup and operation. In addition, built-in plotting functions allow monitoring trends such as drift. These supplies provide the flexibility required for both benchtop and automated test system applications. For example, they provide a list mode, triggers, and other speed optimization functions to minimize test time in automated testing applications. Whether your test requirements are uncomplicated or complex, the Series 2280S supplies provide a simple way to set up all the required parameters.
Measure Rapidly Changing Loads
To monitor fast-changing and pulse-like load currents properly, Series 2280S supplies offer the speed necessary to capture load changes that occur at intervals as short as 140μs. This capability allows designers and manufacturers of portable, battery-operated devices to monitor load currents easily in all of a device's operating modes so they can determine the device's total power consumption.
This high speed measurement capability allows measuring each state of a power-up load sequence and a power-down sequence. Measurements can be made as fast as 2500 readings per second, making it possible to characterize and test the current draw at each of the start-up states.
Perform Semi-Automated Testing Right on Your Bench
Test your design over its operating voltage range automatically or study how it responds to DC output changes by using the Series 2280S supplies' built-in List Mode function. Create and save up to 10 lists of sequenced voltage levels with up to 99 distinct voltages in each list. The duration of each voltage level can be set as short as 1ms or as long as 60s. Create simple linear ramps or any custom configuration from either the front panel or an interface bus. A single trigger will automatically execute the list once or multiple times.
Automate a test quickly and easily with KickStart software
Set up an automated test for the Series 2280S supplies in four simple steps, without writing a line of code, with the KickStart start-up software. KickStart provides both graph and spreadsheet displays. The saved data can be exported to data analysis programs or used in a screen shot of the plot for reproduction in test reports. Up to 15,000 data points can be stored. Free download from Keithley.
