Series 2281S Battery Simulator and Precision DC Bench Power Supply

The Keithley 2281S Battery Simulator and Precision DC Power Supply combines a high-performance programmable power supply with real-time battery simulation, allowing you to test devices as if they were connected to a real battery. With up to 120W output, it accurately simulates charge/discharge behavior, tracks state-of-charge (SOC), and supports detailed battery model creation.Featuring 6½-digit precision and ultra-low output noise, the 2281S is ideal for benchtop R&D and automated test setups where accuracy and repeatability are essential.

The 2281S-20-6 Dynamic Battery Simulator and Precision DC Bench Power Supply with TFT LCD display uses a model to emulate the response of a battery over its discharge cycle. Since the model can be based on the average current of the product that the battery will power, you can estimate battery life and analyze product performance over the life of the battery. It comes with 5 built-in battery models ready to be used.
