The Keithley 2290E-5 is a single-output 5 kV DC power supply engineered for high-voltage component testing, materials research, insulation validation, and high-energy physics experiments. It delivers precise programmable voltage and current control across a 50 V to 5000 V range with 5 mA maximum output current and 55 W maximum power. The instrument combines low-noise performance—down to 1.0 mVRMS at 1 kV with selectable filtering—with fast transient response and arc/short-circuit protection, making it suitable for applications demanding both accuracy and safety.
