-   5mA maximum current
-   25W maximum power
-   120VAC nominal input voltage
-   Low noise for precision sourcing and sensitive measurements
-   Selectable filters reduce noise to less than 3mVRMS
-   Safety interlock controls high voltage output
-   IEEE-488 programmable
-   Protection module prevents damage to low voltage instrumentation

**Applications**

The Keithley 2290-5 5 kV Power Supply w/120VAC Nominal Input Voltage facilitates high-voltage device and material testing, as well as high-energy physics experimentation. The 2290-5 offers up to 5000V voltage outputs and has a 5mA current capacity; it measures both an output voltage with 1V resolution, and an output current with 1μA resolution. In addition to the voltage and current output displays, a third display shows one of four settings: output voltage, voltage limit, current limit, or current trip. These values can be set precisely with the front panel keypad. The settings can also be programmed over the IEEE-4888 interface, or the output voltage can be set with an analog control voltage.
