Description
Ten kilovolts sits far beyond an ordinary bench supply. The Keithley 2290-10 high-voltage supply delivers up to 10,000 V from a single output, though at a modest current. Lost in HCM lists it for rental and sale and arranges service on request.
The Keithley 2290-10 high-voltage supply: ten kilovolts, one milliamp
The current ceiling is 1 mA, so this is a voltage source for light loads. That suits high-voltage device testing and research work where the load barely draws current. However, it will not drive a heavy load. Compare your device’s current need with that limit before you ask for a quote.

Control from a rack or a script
GPIB and RS-232 link the high-voltage supply to a computer, and analog control adds a third route. For example, a test program can raise the voltage in steps and log each point. The product photo shows a pair of 2290 series units with red LED readouts and a keypad, so treat it as a series reference.
Respect the voltage
Even at 1 mA, ten thousand volts calls for care. Use cables, connectors and clearances that suit the voltage, and confirm grounding and the safety interlock before you switch an output on. The current Keithley manual covers wiring and safe limits, so read it before you connect anything. The listing for this model does not state an AC input, so ask Lost in HCM which line option the unit carries.
Rent or buy the Keithley 2290-10
A one-off high-voltage study suits a rental. A lab that repeats the same tests every week may prefer to buy the Keithley 2290-10 high-voltage supply. To start, request a quote from Lost in HCM and list your dates, site and accessories. You can also compare other power supplies, read about Keithley on the Tektronix site, or contact SMK Vietnam.
2290-10 questions
Does the 2290-10 have a LAN port?
The listing names GPIB, RS-232 and analog control only. Ask Lost in HCM if you need Ethernet.
How does it compare with the 2290-5?
The 2290-5 lists 5,000 V at 5 mA. It gives up half the voltage in return for five times the current.
What AC input does it need?
The listing does not say. Confirm the line option with Lost in HCM before you plan the installation.
