Welcome
Thank you for choosing a Keithley Instruments product. The 2281S Precision DC Power Supply and
Battery Simulator is a high-sensitivity, low-noise, programmable instrument that sources stable,
low-noise voltage and can monitor load currents over a wide dynamic range, from amperes to
nanoamperes.
In addition to serving as a power supply, it can conduct battery testing by charging and discharging
the battery under test and creating a model for the battery. The 2281S can also simulate batteries to
facilitate tests conducted on the products supplied by batteries.
The high-resolution, 4.3-inch TFT color display presents numerous parameters that describe the state
of the instrument to enable you to get the most information from your measurements.
Extended warranty
Additional years of warranty coverage are available on many products. These valuable contracts
protect you from unbudgeted service expenses and provide additional years of protection at a fraction
of the price of a repair. Extended warranties are available on new and existing products. Contact your
local Keithley Instruments office, sales partner, or distributor for details.
