Keithley 2281S-20-6

Keithley 2281S-20-6 Programmable Power Supply

(1 Ch, 0V, 20V, 0A, 6A)

The Keithley series 2281S Battery Simulator and Precision DC Power Supply combines battery simulation with the functions of a high-precision power supply. The 2281S-20-6 can analyze the DC current consumption of a device under test and generate a battery model based on a battery charging process, and simulate a battery based on a battery model. The 2281S-20-6 can output 120W with 20V and 6A, and sink current up to 1A.

The 2281S uses linear regulation to ensure low-output noise and superior load current measurement sensitivity. A high resolution colour 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 to provide an easy-to-navigate user interface for fast setup and operation.

In addition, built-in plotting functions allow monitoring trends such as drift. These features provide the flexibility required for both bench-top and automated test system applications. In addition, the 2281S provides a list mode, triggers, and other speed optimization functions to minimize test time in automated testing applications.
