The Keithley 2281S-20-6 single channel, Precision DC Supply and Battery Simulator innovatively integrates the functions of high-precision power supply, battery test, and battery simulation. The Keithley 2281S 20 6  is able to analyze the DC consumption of a device under test, test a battery and generate a battery model based on battery charging process, and simulate a battery based on the battery model. The Keithley 2281S-20-6 can output up power to 20 V and 6 A, and sink current up to 1 A. The 2281S use linear regulation to ensure low output noise and superior load current measurement sensitivity. A high resolution color Thin Film Transistor (TFT) screen displays a wide range of information on measurements. Soft-key buttons and a navigation wheel combine with the TFT display provide an easy-to-navigate user interface that speeds instrument setup and operation. As well, it has built-in plotting functions that allow monitoring trends such as drift. These features provide the flexibility required for both benchtop and automated test system applications.

Futhermore, the Keithley 2281S-20-6 provide a list mode, triggers, and other speed optimization functions to minimize test time in automated testing applications. A choice of front or rear panel terminals provides enhanced connection flexibility. For maximum voltage accuracy, 4-wire remote sensing ensures that the output voltage programmed is actually the level applied to the load. Additionally, the sense lines are monitored in order to detect any breaks in them. These features ensure any production problems can be quickly identified and corrected. Series 2280S supplies can be controlled via their built-in GPIB, USB, or LAN interfaces. The USB interface is test and measurement system (TMC) compliant. The LXI Core compliant LAN interface supports controlling and monitoring the Keithley 2281S-20-6 supply remotely, so test engineers can always access the power supply and view measurements, even if they're located on a different continent than their test systems. Measuring a battery during charging/discharging process In the Keithley 2281S battery test function, you can conduct a charging/discharging test on a battery. Charging current ranges from 0 to 6 A, and the maximum discharging current is 1 A. During the charging, you can set the sampling interval for the internal 6.5 digits multi-meter to sample the charging current and voltage continuously. Then the capacity of the battery is integrally computed, also the ESR will be computed. All the test result are saved in the internal memory.
