Description
A high-voltage supply only helps if it runs from the power your site has. The Keithley 2290E-5 high-voltage supply lists a nominal 240 VAC input, 5,000 V and 5 mA from one output. Lost in HCM lists it for rental and sale and arranges service on request.
Match the Keithley 2290E-5 high-voltage supply to your mains
A 240 VAC input sits closer to Vietnamese factory mains than the 120 VAC input of the 2290-5. Still, the listing says nominal, so ask Lost in HCM about voltage tolerance and the power cord. So that one question can save a day of setup, and it costs nothing to ask.

Where a 5 kV, 5 mA source fits
Research benches, device characterization and high-voltage device testing all call for a source like this. With the Keithley 2290E-5 high-voltage supply, a GPIB link lets a test program set the output, and the analog control input gives a second way in. In the product photo, red LED displays show voltage and current while a keypad handles manual entry. The photo shows a pair of 2290 series units, so read it as a series reference.
Before you request a quote
State your site mains, the cable run, your fixture design and the computer that will command the supply. Then Lost in HCM can also check the unit and any accessories against your plan. Also confirm grounding and the safety interlock, and follow the current Keithley manual for safe limits.
Rent or buy the 2290E-5
A short high-voltage project fits a rental. However, a permanent test station suits a purchase of the Keithley 2290E-5 high-voltage supply. In both cases, request a quote from Lost in HCM. You can also see more power supplies, read the Tektronix pages for Keithley, or contact SMK Vietnam.
2290E-5 questions
What input voltage does the 2290E-5 list?
It lists a nominal 240 VAC.
How does it differ from the 2290-5?
The listings give the same 5,000 V and 5 mA. The nominal AC input differs: 240 VAC here against 120 VAC. Ask Lost in HCM about anything else.
Which connections let a test computer command the 2290E-5?
GPIB does. The analog control input offers another route if your setup drives it that way.
