Keithley 2290-5 - 5 kV Power Supply, 120 VAC Nominal Input Voltage, 5mA

Keithley 2290-5 High Voltage Power Supplies facilitate high voltage device and material testing, as well as high energy physics experimentation. The 2290-5 5kV Power Supply provides voltage outputs up to 5000 V. The 2290-5 has a 5 mA current capacity. These supplies measure both output voltage with 1V resolution and output current with 1 μA 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.

Low Noise Ensures Accurate Low Level Measurements

Low output noise is essential when using sensitive measurement instruments to make leakage current or high resistivity measurements. The maximum output ripple of the 2290-5 is 100 mVRMS. Two selectable, internal filters on the 2290-5 reduce the maximum output ripple to only 3 mVRMS. Extremely low noise from both power supplies enables sensitive measurement instruments to make accurate current measurements down to picoamp levels.
 

Typical Applications

• High voltage device breakdown testing
• High voltage component testing
• Insulation testing
• High voltage resistivity measurements
• High energy physics research

When low voltage measurement instrumentation is used in the high voltage circuit, the protection module safely clamps the voltage across the instrument to a maximum value of 200V even when a device under test (DUT) breaks down. Thus, a Keithley 2290-5 Power Supply, 2290-PM-200 Protection Module, and Keithley accessories provide all the elements for building a safe, high voltage test environment.

Make Precise Current Measurements Lower Than 1 μA

Use a sensitive Keithley measurement instrument, such as a Keithley SourceMeter^® SMU instrument, to measure current drawn by the device under test (DUT) that is below the sensitivity of the Keithley 2290-5 Power Supplies. Keithley SourceMeter SMU instruments can provide sensitivity as low as 0.1fA. The following diagram shows how the 2290-PM-200 Protection Module protects the low voltage SourceMeter SMU instrument from high voltages when the DUT breaks down. The leakage current of the Protection Module limits the measurement resolution to picoamp levels, which is five decades more sensitive than the current measurement resolution of the Keithley 2290-5 Power Supplies. Keithley can provide a complete high voltage test capability with the most current measurement sensitivity available anywhere.
 

Easily Automate a High Voltage Test System

The Keithley 2290-5 IEEE-488 interface allows the creation of an automated high voltage test system. Software drivers are supplied to simplify and accelerate test system development. This further enhances safety as the high voltage can be controlled from a remote location.
