About Power Supplies
A power supply is an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.

The 360W versions can output current of 36A, 13.5A, 4.5A, or 1.44A; the 720W models can output 72A, 27A, 9A, or 2.88A; and the 1080W instruments can output 108A, 40.5A, 13.5A or 4.32A.
Keithley 2280S-32-6 192W DC Power Supply
192 Watts, 32V Maximum Voltage
Series 2280S supplies deliver up to 192W of low output noise power and superior load current measurement sensitivity. Built-in plotting functions allow monitoring trends such as drift.
Keithley 2280S-60-3 192W DC Power Supply
192 Watts, 60V Maximum Voltage
Series 2280S supplies deliver up to 192W of low output noise power and superior load current measurement sensitivity. Built-in plotting functions allow monitoring trends such as drift.
Keithley 2281S-20-6 20V Battery Simulator
1 Output, 20 V Maximum Voltage
The 2281S-20-6 Dynamic Battery Simulator 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.
Keithley 2290 5,000V/10,000V High Voltage Power Supply Series
Single Out, 5,000V or 10,000V High Voltage Power Supplies
Series 2290 High Voltage Power Supplies are ideal for high voltage device and material testing, as well as high energy physics experiments. Choose the Model 2290-5 Power Supply for voltage outputs up to 5000V or the Model 2290-10 Power Supply for up to 10,000V.
Keithley 2300 Battery Simulating DC Power Supply Series
Single & Dual Outputs, Programmable Output Resistance
Testing portable, battery-operated devices under real-word conditions demands a DC power supply that can simulate a battery’s performance over a wide range of conditions. Series 2300 battery simulating power supplies can simulate both a battery's output resistance and output voltage response.
