Keithley 2281S-20-6 Precision DC Supply

Key Features:

• Simulate a real battery output up to 6A sourcing current (charging) and 1A sinking current (discharging)
• Generate battery models automatically by recording a battery's characteristics during a full charging cycle
• Import/export fully customizable battery models using a simple CSV file format
• Test and validate your battery's capacity and Equivalent Series Resistance (ESR)
• Monitor key battery parameters intuitively on graphical user interface

The Series 2281S Battery Simulator and Precision DC Power Supply innovatively integrates battery simulation with the functions of a high-precision power supply and battery testing. It’s 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 2281S-20-6 can output up power to 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 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 to provide an easy-to-navigate user interface that accelerates instrument setup and operation. In addition, built-in plotting functions allow monitoring trends such as drift. These features provide the flexibility required for both benchtop 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

Battery simulation based on a battery model In the battery simulator function of the 2281S, real battery output performance can be simulated based on a selected battery model. State of charge (SOC) and voltage open circuit (Voc) can be set to any state to test the device under specific circumstance. There are two modes from which to choose:

• Static: During the static simulation, Voc and SOC stay the same.
• Dynamic: During the dynamic simulation, Voc and SOC change according to charging and discharging as with a real battery.

Capacity can also be reduced to accelerate the charging and discharging process for better test efficiency
