Keithley 2281S-20-6

Precision DC Supply and Battery Simulator, 20V, 6A


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, generate a battery model based on the battery charging process, and simulate a battery based on the battery model. The 2281S-20-6 can output voltage and current up to 20V and 6A and sink current up to 1A.


  • Simulate a battery's output during the charge and discharge cycles

  • Create, edit, import, and export battery models

  • Build a library of battery models automatically based on measurement results using battery test mode

  • Display the real-time change of the state of charge (SOC), open circuit voltage (Voc), and terminal voltage (Vt) for the simulated battery

  • Compute battery capacity in amp-hour and equivalent series resistance (ESR)

  • Program the battery SOC, Voc, capacity, and resistance

  • Provide two modes of simulation — dynamic and static

  • Monitor charge/discharge current and voltage

  • Output up to 120W of low noise, linear regulated power

  • Monitor load currents from 100nA to 6A with high accuracy

  • Measure voltage and current with 6½-digit resolution

  • Sink current up to 1A and source current up to 6A

  • Built-in graphing simplifies analyzing trends or displaying voltage or current waveforms

  • High resolution TFT display and soft-key/icon-based user interface simplify power supply operation

  • Digital I/O for direct communication with other devices and instruments

  • GPIB, USB, and LAN interfaces

  • Emulation of front panel display and controls via your web browser simplifies automated control and monitoring
