Keithley 2280S-60-3 – Precision Measurement DC Power Supply, 60 V, 3.2 A

Measure Rapidly Changing Loads

To monitor fast-changing and pulse-like load currents properly, 2280S-60-3 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 powerdown 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 startup states.

View and Control Every Parameter of the Supply for Maximum Performance

The bright, 4.3-inch TFT display shows voltage and current readings, the source settings and many additional settings in large, easy-to-read characters. The iconbased main menu provides all the functions users can control and program for fast access to source setup, measurement setup, display formats, trigger options, and system settings. Menus are short, and the menu options you need are easy to find and clearly described, so that you can set up test parameters quickly by using the navigation wheel, keypad, or soft-keys. Many set-up parameters, such as for voltage and current settings, can be entered directly from the home screen; less complex tests don’t even require accessing the main menu to make adjustments. Whether your test’s requirements are uncomplicated or complex, the 2280S-60-3 supplies provide a simple way to set up all the required parameters.

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-60-3 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.

Controlled Rise and Fall Times Protect Devices Under Test

Are you working on a device or a system with a high inrush current? 2280S-60-3 supplies allow programming the voltage output’s rise time to slow the voltage ramp and avoid voltage overshoot, which could potentially damage the DUT. The voltage fall time can also be controlled to prevent a fast ramp down of the output voltage. Voltage rise and fall times can be set as slow as 10 V/s or as fast as 100V/s. Small voltage transitions can be programmed to rise and fall as fast as 1000 V/s.

Trend Analysis and Load Current Characterization

Use the built-in graphing function to monitor the stability of the load current or capture and display a dynamic load current. Or, use it to view a start-up or turn-off load current. 2280S-60-3 supplies can take measurements quickly and store up to 2,500 measurement points. In addition to displaying a voltage or current waveform or both, they can compute statistics on the stored data. Statistical calculation options include average, maximum, minimum, peak-peak, and standard deviation. All the information you need is accessible through a few display menus.

Automate a test quickly and easily with KickStart software

Set up an automated test for the 2280S-60-3 supplies in four simple steps with the KickStart start-up software. Once the program is open, perform these steps: create a test file, select the 2280S-60-3 power supply, select the power supply application, and enter the test parameters. Run the test, and get results without having to write a line of code. KickStart provides both graph and spreadsheet displays. Data is saved to the test file, and the data can be exported to data analysis programs. Or take a screen shot of the plot for reproduction in test reports. Up to 15,000 data points can be stored. KickStart may be all the software you ever need.
